Customer Question

I have a 2003 Holden Astra 1.8 auto. It goes into limp mode. Fault codes P1895, ECM actual torque signal malfunction, P0725 Engine speed circuit input, P1700 trans service required and p0335 crank angle sensor. I have changed the crank angle sensor, MAF, cleaned throttle body, changed coil pack. It runs fine for a short time than limp mode. The only way to drive it is manually select gears.

Thank you. At last somebody who knows what he is talking about. I know it's rather complicated but does seem possible. I just have one last question. My car is out of rego at the moment till I get this problem fixed. Can I swap a known good ECU and key reader to cure problem or can I take ECU to Holden with pin code and have them reprogram it. If it all works out you will get 5 stars from me.
Thanks again

Hi Ray,You don't need to change the key reader (immobiliser), but that is what some do when they don't have access to the programming tools that a Holden dealer will have.If you have a good known ECU, it needs to be reset (unlinked from immobiliser), code needed here.Then you fit it to your car and link it to your immobiliser with your code.If you don't know the code/s I can get them for you, just post your VIN numbers from both cars.The new ECU would be worthwhile to get SPS programmed if updates are needed.Hope this helps.Gary

Hello Gary
Just a little follow up on Astra problem. I swapped ECU and immobiliser from spares car to no avail. Engine ran for a few seconds, shut down and would not restart.
Put the ECU and immobilizer back into spares car which had no problems. Started car and got same error codes and symptoms as first astra. I than realisied I had not put crank angle sensor in engine. I fitted crank angle sensor, cleared all error codes started engine and everything was back to normal.
From this I have deduced the problem is in the wiring from the crank angle sensor or still possibly the ECU.
Thanks for all the help
