astra h help

[Jack 666]

Hi, Can anyone help me with this fault on a 2009 Vauxhall astra H.1.7ctdi diesel When scanned with opcom I get the fault crankshaft sensor out of range. the sensor has been replaced and the wiring to the ECU has been checked and found to be ok. The vehicle will not start and when live data is monitored tacho reads revs but cam sensor does not read anything, this has been replaced as well. When I unplug crankshaft sensor the camshaft sensor reads ok. This has got me puzzled so any help here would be appreciated. Thanks Jack.
Sorry I forgot to put fault code. The code is P0335 (28).
I have checked timing belt and timing and this appears to be ok.
Thanks for your quick response.

have you checked the engine phase?

The exact error code would have helped. As our colleague alexbroccoli said, was the distribution (timing belt) checked? With the ignition on, if you read the errors stored in the ECU, do you find any faulty sensor between the two, or only after you try to start the engine?
Also pay close attention to the ECU, they have problems with infiltrated water.
The two sensors are interchangeable, if I remember correctly.

Thanks for your answer.What is engine phase

[Jack 666]

Hi thanks for information It has a Bosch ecu and I have tried replacement, same fault code.
Timing has been checked as well.
engine does not start and fault codes can be cleared, but upon cranking engine fault re appears.

If the ECU is BOSCH, then the engine is the old one, Z17DTH or Z17DTL, in which case the sensors are not interchangeable. I thought it was Z17DTJ or Z17DTR.
In your case, we are dealing with another kind of crankshaft sensor.
I tend to think that the problem can be shielding the wires from the sensor to the ECU.
Check the ground wire between the engine block and the body, the integrity of the wires from the sensor to the ECU and their shield (it is very important).
The contacts in the sensor socket can be checked by measuring the resistance of the sensor, directly in the ECU socket, we should measure 880 Ohms.
If the ECU and the sensor have been replaced with some that are definitely ok, then this could be the cause. (and maybe an inspection of the teeth on the flywheel.

Would like to back up every which way above member Sabotage has said

1) how long you had this car
2) what happens - went to shop, came out shop nil poi?
3) any other recent work done

"​Sabotage" ? Heh...

Solved at last, the problem was crankshaft timing wheel it had a missing tooth. I dont know how this could have happened as this vehicle was driving and just stopped. We decided as this was quite an old van it did not deserve an entire removal and strip down of the engine due to the amount of time that would be involved. our solution was to mount a new sensor wheel and sensor on the front pulley. I have enclosed photographs of the modification. The van is up and running well. Thanks for all your replies, I hope this can be of benefit to anyone else with this problem.DSCF0971.JPGDSCF0972.JPGDSCF0974.JPGDSCF0975.JPGDSCF0976.JPG

Thats well awesome can you explain more in detail for us leechers how you got new pick up
in correct place and where pick up wheel purchase from?

thanks

[Jack 666]

To get pickup in correct place we turned engine by hand until we could see the trigger point by looking through the hole in the engine block where the original sensor would go. We used one of those inspection cameras with the flexible optical cable. We then decided where to mount sensor and aligned the trigger point and marked everything before drilling pulley and spacer. Sorry I dont know who can supply the timing wheel , We purchased a second hand crankshaft from ebay just to get timing wheel. Perhaps trying Isuzu or Opel parts supplier might help. Cheers Jack.
