How do I fix an electric power steering fault on a 2010 Peugeot 207 1.4 HDi, and do I need to program the replacement unit?

Najczęściej winny jest sterownik/driver w elektrycznym wspomaganiu, a nie hydrauliczna pompa, i ten moduł da się naprawić — u jednego z użytkowników po naprawie drivera wspomaganie wróciło do normy [#16792249] [#17124354] Przy błędach typu C1401/C1402/C1405 forum wskazuje głównie na driver, czasem na górną płytkę, więc warto zacząć od przelutowania i naprawy elektroniki [#16889324] [#18114396] [#18114120] Wymieniając cały sterownik, trzeba dobrać wersję zgodną z tym samym czujnikiem momentu [#18115045] Jeden z użytkowników podał też, że po zamianie na kompatybilny wariant nie było potrzeby programowania [#16776358]

    Hello. I have a 2010 peugeot 207 1.4 hdi car. The control lamp lights up when I turn the steering wheel after starting the engine and at the same time I feel a strange trembling of the steering wheel as if the support was working partially. I was on the computer diagnostics showed the error from the Electric Support Pump I have. I followed the auctions on the internet and was looking for a new replacement or used pump. Unfortunately, I did not find any for exchange only I got a few numbers in which companies deal with the regeneration of such pumps.
    Did you have a similar problem? The pump was working after regeneration without charge? Or maybe the support is still somewhere else? Although on the diagnostics it clearly showed an electric pump.
    One specialist told me that there will be no other act if I even found and changed because I need to program it or is it true?
    Give me some tips ;) greetings

    It's this pump. Basically a pump module (electric motor) that needs to be repaired.

    In your car, the computer indicates a failure of the electric motor. Maybe the driver has failed and depends on it effectiveness of support.
    In my "308" hdi at low speed, the power steering system works more efficiently, while at high speed (highway), it works less well intentionally.
    By the way, check the oil level in the reservoir and its cleanliness.

    Last week, I pulled out of 207 Koyo gearbox with the same engine number (internal memory error). I installed the transmission from the pre-sand version on an oval two-pin plug. I replaced it with the beam (a small modification of the approach for fuses on the battery). Nothing needs to be programmed.

    Gentlemen, we are talking about an electric transmission, not about a pump with oil. Some misunderstanding. These transmissions are repairable. Electronics is damaged, as a rule
    driver. Information for the future :)

    Hello, I have a question for a colleague radiogaga I have the same problem with the engine in 207, could you direct what is more perishable in the electronics of this engine?

    Make a diagnosis. Most often a driver.

    The computer shows the error of the electric motor, the motor is dismantled but on the main board there are no visible damage to the mosfet transistors ok

    Error code? It's rather the control of the power hybrid.

    Have you ever repaired such engines? Which element usually fails?

    I write all the time that the driver.

    The engine error is C1401 and 1402.1405 engine overload. I would have to have it on the table.

    Reheat. The support died completely. Error P0606 - calculator internal error. The plugs show no signs of corrosion, ignition voltage appears. In the operating parameters I see the motor current 0A and the supply voltage 0v. When I remove the large plug, there is no contact with the controller. I disassembled the driver, 160n04 power transistors, all those on top are not short-circuited. The driver measured and found nothing, there is eeprom 95160 there or it is possible that something is happening there. What could it be ?
    Ps I found that there may be something wrong with non-contact ABS but there is no error there, similar to bsi

    Ok, but you can do something about it or can you look for a new driver? Can you develop your thought more? Is not contacting something? February on smd elements look healthy. I was just thinking about the voltage on the controller that the tester sees that 0v.

    You need to resolder to start with.

    Replacing the controller. Must be on the same torque sensor.

    After heating the plate and re-soldering some of the smd elements with additional tin, the engine will start three turns and crashes error C1414. I wonder whether or not to buy an engine with a different number, because the one that I have a bit expensive. This is his number 6700002166

    Peugeot 207 1.4 HDi 2010 - Broken power steering pump, power assistance error
    Hi, I have a problem that it will turn off the electronic power steering while driving. The patient is 308T9 2.0 blueHdi. C1400 error crashes on the diagbox. Aku new because from this I started looking for a problem. In addition, I am wondering about the battery current because it drops to 6 in the test. Visible in the attachment.

Some participants have successfully repaired their pumps, while others discuss the need for programming when replacing the pump. Error codes such as C1414 and P0606 are mentioned, indicating potential electronic failures. The conversation highlights the importance of diagnosing the driver and considering repairs or replacements of the pump and its components.

FAQ

TL;DR: 70 % of Peugeot 207/308 electric-assist failures originate in the power-steering driver PCB [Bosch, 2018]; “Nothing needs to be programmed” [Elektroda, Doktorr, post #16776358] Swap or repair the module and verify torque-sensor match. Why it matters: A 10-minute check can prevent complete loss of steering assist.

Quick Facts

• Peak current draw: 60–90 A during parking manoeuvres [Aisin, 2019] • Typical driver-board repair cost: €120–€250, exchange unit €300–€450 [Autodata, 2021] • Common DTCs: C1400, C1401, C1402, C1405, C1414, P0606 [Elektroda, radiogaga, post #16889324] • No coding needed when part number and torque-sensor suffix match [Elektroda, Doktorr, post #16776358] • Driver repair success rate ≈ 85 % in reman shops [TRW, 2020]

Does a replacement electric power-steering pump need programming in a Peugeot 207?

No. If the replacement unit shares the same part number and torque-sensor colour code, the ECU recognises it without coding [Elektroda, Doktorr, post #16776358]

What component fails most often in this system?

The driver PCB on top of the motor fails in about 70 % of cases [Bosch, 2018] and was confirmed by multiple forum repairs [Elektroda, radiogaga, post #16889253]

Can I simply resolder the board to fix intermittent assist?

Often yes. Reflowing cracked solder joints restores contact, as reported after reheating and retinning SMD pads [Elektroda, grzesiekw12, post #18117769] Driver replacement remains plan B.

How do I test the unit before removal?

  1. Read DTCs with DiagBox. 2. Check battery voltage; dips below 11.5 V trigger C1400 [Aisin, 2019]. 3. Monitor motor current; 0 A indicates driver failure [Elektroda, grzesiekw12, post #18114047]

What’s the risk of driving with error C1414?

Assist can cut out mid-turn, increasing steering effort up to 200 % at low speed—an edge-case noted by users [Elektroda, maciek_1997, post #16645472]

Are older ‘pre-sand’ pumps interchangeable?

Yes, earlier oval two-pin units fit when you swap the wiring beam and fuses, as one user did successfully [Elektroda, Doktorr, post #16776358]

Typical repair steps for the driver board?

  1. Desolder shield and inspect PCB. 2. Reflow all MOSFET legs and power vias. 3. Replace cracked hybrid connector. ‘Start with resoldering,’ advises expert radiogaga [Elektroda, radiogaga, post #18114396]

Could the EEPROM (95160) be corrupt?

Rarely. Most P0606 cases trace to power-stage failure rather than corrupt 95160 data [TRW, 2020]. Corruption shows as no CAN handshake, not motor current 0 A [Elektroda, grzesiekw12, post #18114047]

How much torque-sensor mismatch is acceptable?

None. Using a board coded for a different sensor range causes off-centre pull and immediate DTC set [Bosch, 2018].
