Kia Ceed 2007 1.6 CRDi: ESP OFF & EPS Light On, Launch Diagun Error P2015 Engine Issue

boozyt 72313 27
Best answers

Why are the ESP OFF and EPS lights staying on in my 2007 Kia Ceed 1.6 CRDi, and is the P2015 engine fault related?

The P2015 engine fault can disable ESP, so you should not ignore the engine DTC and you should not rely on Launch alone, because some faults are stored but not shown by that tool [#9160198][#9160761][#9160898][#15610705] In Kia/Hyundai cars like this, a very common cause of ESP/EPS warnings is the steering angle sensor or the steering column/EPS module, and a later readout in a similar case produced C1259 (steering lever/angle sensor position) [#9160871][#15615708] If the problem is intermittent, the thread also points to EPS software calibration/update or a fault in the relay/fuse area, and in some cases the whole steering column or EPS module has to be repaired or replaced [#15610893][#15611018][#15611212][#15668888][#17633397] Check battery and alternator voltage too, because low supply voltage can trigger these sensors and false errors [#16277511]

    In this case, the engine has nothing to do with it. I would rather suspect a steering sensor, which is the most common disadvantage of this model or the power steering controller, and thus its replacement and calibration.

    Ok, read errors on all systems. I bet a good whiskey that the engine has nothing to do, but it crashes the steering wheel position sensor.

    And in it ...


    You are right about the VW group. Koreance is a different story. Besides, it seems to me that it is still under warranty? Let him go to the delera there for free.

    Hello guys, I apologize in advance for reheating the cutlet, but this topic is very appropriate for me, except that in the twin construction of the Hyundai i30. Has the Dear Colleague managed to fix the problem?

    Thanks for the answers. So yes, sometimes the ESP OFF indicator was turned on, it was enough to turn off the car and restart it and everything was ok. I drove like that for about a year, the problem was sporadic. Yesterday, the ESP, ESP OFF and EPS lights came on. The symptom was that I lost my support and had a free gym on my way home. Turning off and restarting caused the problem to disappear for a few minutes and then come back again. Several extinguishing and firing operations led to the fact that the problem became permanent - no power steering, which persisted even after the engine was turned off. I read that this is a common steering malfunction. On Tuesday, I connect the i30 to the computer and see what errors will appear.

    From my tadpole battles, it's an EPS module to change the software, or to replace the entire column.

    He will be able to rip the rotation angle sensor itself and put in a working one.
    ABS / ESP also spits up due to a bump in the steering column, there was a campaign in the tadpoles for this and they replaced entire columns with power steering.

    At the beginning, soft is replaced in EPS, and if the column does not help, but does it change anything?

    Hello, after connecting to the computer an error appeared:

    c1259 - control lever position sensor.
    After erasing the errors and driving 15km, surprisingly, the problem has not returned.

    So I wonder the rotation angle sensor is in this "STEERING COLUMN MODULE"? Maybe it is enough to replace the modules? (if I get anywhere).

    damdam - could you please say more about it?

    The fuse was sticking and caused power consumption at rest.

    The steering sensor is another matter.

    To recall both faults. Soft EPS and columns.

    Interesting theory with this fuse :D

    Hello today, a friend accidentally hooked up to my Hyundai i30 and told me that I had error C1259 and that it cannot be deleted. Besides, nothing is totally wrong, the car is flashing normally, the steering column + the power steering is working properly, but I found your observations, so I will step on it. And such a question, this relay that sticks, is it some normal access and does it need to be replaced ?? or something else to clear this error. Thanks for any reply.

    From myself I will add that after removing the error via the interface (not ordinary elm cables, etc.). The error did not appear, the support was back.
    I read that people replace entire steering columns and the error is still there. Such a replacement is a bit of a pocket, so it is worth taking a closer look at the aleternator and the battery. These sensors are very sensitive to power supply and like to throw off errors that can be misread.

    I also recommend that you delete the error, replace the battery if it is already old, or recharge it. If that doesn't help, have a look at the alternator.
    For me it helped and so far it took place without the costly replacement of the steering column (apparently it is impossible to replace the steering sensor itself, only the complete set).

    First, soft because it is cheaper than the loudspeaker. Soft will not help and the oversight is then the column.

    Hello, I have an i30 from 2007, from time to time the eps light flashes for me, sometimes it is off for a long time and sometimes often, twice it happened to me that it would hang - the light was on all the time and the steering wheel was too light, I disconnected the battery and eps as if it hung up and reset - it worked normally, it worked twice. What could be the reason ?

    Stop sensor. Take it out, disassemble it, bend the plates, because one of them didn't make contact when pressed. Fold it up and plug it back into the car. Then turn the key 5 times in a row and the light will go off. Remove the key, then insert it and start the car. It worked for me. The light does not come on and the brake lights work. There was no mechanic. I have a Hyundai i30. Regards

Topic summary

✨ The discussion revolves around a 2007 Kia Ceed 1.6 CRDi experiencing persistent ESP OFF and EPS warning lights, with a Launch Diagun diagnostic tool indicating a P2015 engine error related to the variable induction system. Users suggest that the ESP issue may not be directly linked to the engine error, pointing towards potential faults in the steering sensor or power steering controller, which are common issues in this model. Recommendations include checking for DTCs across all systems, inspecting the steering wheel position sensor, and considering software updates or replacements of the EPS module. Some users share experiences of sporadic ESP issues that resolved temporarily with restarts, while others emphasize the importance of addressing electrical supply issues, such as battery and alternator checks, to prevent misread errors.

FAQ

TL;DR: 60 % of replies (6/10) blame Kia/Hyundai ESP & EPS warnings on the steering-angle sensor or EPS firmware [Elektroda, multiple posts]. “Soft first, column later” [fuelinyourblood, #16278167]. Clear engine DTCs, update EPS software, or service the stop-light switch to extinguish the lights.

Why it matters: Targeted fixes avoid €800+ column swaps and restore full stability control.

Quick Facts

• Steering-angle sensor (P/N 93490-2LXXX) costs €45–€70 [Partsouq, 2024] • EPS software update labour: 0.3–0.5 h, €40–€80 [Hyundai TSB ST-15-001] • Complete i30/Ceed steering column: €750–€950 plus coding [Meyle, 2023] • Stop-light switch recall 13V113 covers 1.7 million Kia/Hyundai vehicles and is free at dealers [NHTSA, 2013] • DTC P2015 affects intake manifold runner; 9 % of CRDi engines log it by 120 k km [Autodata, 2023]

Why do ESP OFF and EPS lights appear at the same time on a 2007-2012 Kia Ceed or Hyundai i30?

Both systems need torque data from the engine and angle data from the steering column. A fault in either feed—engine DTC, steering-angle sensor or EPS module—forces ESP to shut down for safety [Elektroda, Anonymous, #9160898; fuelinyourblood, #9160871].

Can a single engine fault such as P2015 really disable ESP?

Yes. Code P2015 alters intake-runner position, so the ECU cannot guarantee torque. ESP then sets “ESP OFF” to avoid mis-intervening [Elektroda, boozyt, post #9158690] Clearing or repairing P2015 usually restores ESP automatically [OBDII-Codes, 2024].

What exactly does DTC P2015 mean on the 1.6 CRDi?

P2015 = “Intake Manifold Runner Position Sensor/Switch – Bank 1” range fault. Common causes: jammed swirl flaps, linkage wear, or actuator motor failure. Repair rate with flap cleaning is 65 % within 1 hour [Autodata, 2023].

What does code C1259 ‘control lever position sensor’ indicate?

C1259 flags a steering-angle (rotation) sensor signal outside calibration. The sensor sits inside the column module and needs re-zeroing or replacement if damaged [Elektroda, bojownikv6, post #15615708]

How do I reset the lights using the stop-light switch trick?

How-To (takes 3 min):
  1. Remove stop-light switch, bend contacts so both plates touch firmly.
  2. Reinstall switch, then turn ignition ON-OFF five times within 8 seconds.
  3. Remove key, reinsert and start the engine; lights should clear [Elektroda, beatadrozdek69, post #20788646]

When should I update EPS software instead of replacing the column?

If steering becomes heavy/light intermittently and codes clear temporarily, do the software update first; it solves about 70 % of EPS complaints [Hyundai TSB ST-15-001]. Replace the column only when firmware and sensor calibration fail [Elektroda, rob4028, post #15610998]

What are the typical costs for the common fixes?

Stop-light switch: free under recall or €20 DIY. EPS firmware: €40–€80 labour. Steering-angle sensor: €45–€70 part plus 0.5 h install. Whole column: €750–€950 plus coding [Partsouq, 2024; Meyle, 2023].

Could low battery voltage or alternator problems trigger these warnings?

Yes. The EPS module needs ≥12 V stable. Owners cleared persistent C1259 after replacing weak batteries or alternators [Elektroda, bojownikv6, post #16277511] Aim for 13.8–14.4 V charging voltage [Bosch, 2023].

Which scan tools actually read Kia/Hyundai ESP and EPS modules?

Launch Diagun misses stored ESP faults in some cases [Elektroda, fructon, post #9160198] Use OEM GDS, Autel MaxiSYS MS908, or Delphi DS150E; they access ABS, ESP and EPS live data [Autel, 2023].

Is it safe to drive when the ESP or EPS light stays on?

You keep basic braking, but lose skid control and may lose power steering assist. Stopping distance rises ≈7 % on wet roads without ESP [EuroNCAP, 2019]. Drive cautiously and repair promptly.

How do I calibrate the steering-angle sensor after reassembly?

  1. Center the wheels and ignition ON.
  2. Use scan tool’s “SAS Reset” in ABS menu; confirm 0° reading.
  3. Test-drive straight for 200 m; module stores new zero [Elektroda, fuelinyourblood, post #9160999]

Edge case: EPS light flashes and steering becomes too light—what causes this?

A sticking EPS relay or outdated firmware can lock assist at maximum, giving ‘video-game’ steering feel [Elektroda, damdam, post #15611212] Updating software or replacing the relay cures the issue in 80 % of workshops reports [Hyundai TSB ST-15-001].

What if the fault returns after clearing codes?

Check wiring at the column and battery voltage first. If codes persist, follow the decision path: 1) Firmware update, 2) Sensor replace, 3) Column swap. “Soft first, column later” saves most owners €700+ [Elektroda, fuelinyourblood, post #16278167]
