[Solved] Astra H 1.6 XER: Camshaft Phase Sensors Issues, Error Codes, Loss of Power, and Resistance Values

Hello everyone. I have astre h 1.6 xer and I have such a problem with sensors. I will say in short two original ones, the mechanic bought new counterfeits and the case looks like that after driving about 30 sometimes only 100 km the car loses power and you can hear the buzzing sound as if the exhaust is leaking and the computer shows an error from the suction side sensor. I bought a used original But there is a problem immediately after starting the car, I even tempted to start a new Continental company and there is a problem with the exhaust although I started working for a while But not the first time. Despite this, the car behaves best on the original, except that it is so raining and you have to stop for a minimum of 10 minutes and works again. I have no more strength. I measured the resistance on the middle and right pins and on those that work is about 15 and on this new and used is 0.27 and probably 0.26 so the difference is huge. Can anyone know what the measurements should be. I have no more strength and the sensors are not cheap. Thanks in advance. Greetings.

And you measured what voltage the sensor gets? And sometimes the installation or ECU is not pounded because these ECUs like to sit down https://www.elektroda.pl/rtvforum/topic3356182.html

Buddy, we start the sensor diagnosis by checking its power supply and output signal.

Yes Yes. The voltage was measured on two plugs from the suction and exhaust and it looks like the middle is the mass and on the right is + 5v and on the left is also 5v (exactly 5.02 va on the right probably 5.03v if it matters), so the sensors get electricity. At this time I ride the original ones and on the way to work (about 10 km), I don't feel anything, everything is okay, even if it gives a bit of "pots". The sensor makes itself felt after larger episodes and the car with the key always lights up (not the check engine, though he blinked once but only once).

First change the oil, then check the condition of the chain whether the belt is there or not. Stretched. Seals in the phasers on the camshaft wheels can be removed. WHAT mistake does it fail?

I suspect that it will end on a run down camshaft if the shaft sensor was damaged, you would not start the car again after switching off the engine.

What exactly is the error description?
It is best to connect an oscilloscope and compare it with the signal on the shaft.
Then it will be known if the sensor signal is strange or timing fault.

Thanks for the answers. I changed the valve a year ago, I change the oil every 15,000. Earlier, the mechanic recommended 10w40 to me, but recently, as I mentioned, I flooded it like in the valvoline 5w30 service book. Sometimes I have a car that does not start the first time and I can hold the starter for 5 minutes and the second time like a child right away. It seems to me that the computer cannot load something and that is why it happens. Errors that shows me has these sensors that I use now are: P0340-04 and only this and when I was playing and I installed other sensors I had errors: P0014-66, P0365-04 and also P0340-04 except that the errors immediately after starting the car I got it and not like in the case that only after some distance. Yes, I think about replacing the shaft sensor, maybe it's his fault? But it does not allow me to sleep why the new sensors and the original used (I do not know if it is working properly) is a different resistance than in the case of the non-original and operating until. I don't have an oscilloscope. I only saw that using the LED diode you can check if it works. I will try to get the diode on days and check.

P0340-04 Intake Camshaft position sensor circuit open (bank 1)
P0014-66 Exhaust camshaft phasing mechanical reference position range / performance
P0365-04 Camshaft position sensor circuit no signal

I am sorry for mistakes in English But in such I have an opcom

Now you crash camshaft sensor error. Check if it gets voltage from the computer 5v power supply. How is it you need to connect a two-channel oscilloscope and compare the signal waveform with the waveform of the shaft sensor. How will they run apart you have the cause in the timing. Unless you do not get any signal from the timing sensor is then the sensor to be dumped.

This error you have says that the motor controller does not see the sensor so it can be: damaged installation between the sensor and engine controller, damaged sensor, damaged motor controller.
Check the installations by unplugging the battery and then the engine control unit and check these three wires under light bulb loading. It is best to check the sensor with an oscilloscope when a problem occurs or buy the original (from the same company as it was in the original). Continental does not make sensors, I would not consider it a decent sensor.

Yesterday I did a route of about 200 km and everything worked. For now, the car is used for commuting. In 20 days I go on vacation so I will have a little time to drive to an electrician. Thank you so much for the answers. I will write what and how it comes out. greetings

Hello after a really long break. I'm going back to the topic again. Well, I replaced the ECU and tried again with sensors; also original but used and in various combinations and the problem has not changed. For some time everything has returned to normal and I recently noticed the error ECN059761 (from the thermostat), I bought it some time ago but I do not have time to replace it and today standing with the engine running I heard the fan turned on and I checked the temperature with curiosity and the display showed 105 degrees, i.e. the thermostat has reached a high temperature. When I started the engine again I had a problem with the sensors and when the temperature dropped, everything returned to normal (temp 68-72 degrees with the thermostat on). I have no more strength for him. I am still asking for help. Thank you I wish you a successful New Year's Eve!

Don't do anything like it rides.

I would like to leave it this way, but I don't like it when something is wrong.

Hello again after a long absence, I found a person who has the same engine and after translating immediately show two errors regarding the intake and exhaust sensor. The computer does not want to accept the original ones and mine does not work until the engine reaches temperature. I have no idea what this is about. Mine also work with him. The timing was checked again and the rollers were not changed. All is well. All in all, if it wasn't for it, my cold ones would not be functional.

Damaged driver then

Welcome back. Today I checked with a diode whether the sensors are working. I checked both original and original both work. Then I checked the car and it turned out that the original ones do not work and the original ones do not give a signal. So I come to the conclusion that maybe the distance between the sensor and the shaft is too great. Some time ago I checked and it seems to be ok. I attach a picture. Now my question is whether and how the roller can "push" more to the right one and the other, and why could it come to the fact that it just stepped back? Thanks in advance.

It is not possible. What is the gap on the original and what on the replacements?

Hello one last time surely. I was able to solve the problem. There was too much "crescent" distance from the sensor (you can see in the photo that there is a trace). I don't know why they changed their place. With a screwdriver and a hammer, I brought them closer to the sensors and, like a hand, turned away. No mistakes. The car smokes after the first one. The engine is totally quieter and the car has regained acceleration. Thank you so much for helping everyone. I hope that this topic will be useful to someone someday. Best wishes.

Problem solved - I'm closing
