Just replaced the TPS and set up as described here on the forum.

 

I was getting eratic gear changes on the auto box, high idle etc.

 

Power light for auto box staying on now after flashing to say that I have a fault stored in the ECU? Cannot get the light off by using centre console switch????

 

ECU code is code 3 - TPS sensor???????

FAO Andy....

 

Reset ECU and connected battery this morning -

 

Started ok as usual with power light out. Ran for approx 30 secs then power light flickering and then on solid.

 

Tryed an auto box diagnostic test and came up fault code 3 TPS again??????

 

Tryed switching using power/hold switch and it then goes out when in hold position. Stays out for a short period then power light back on - even though switch is in normal position???????

 

Any idea were to go from here - ? ECU loom plug check?

 

Pulling whats left of my thinning hair out!!! LOL

 

Cheers,

 

Nigel

Any other members come across this type of problem?

 

Drove car today and the power light is now off but gear changes are too early now and it feels sluggish - shortshifting almost?

 

Checked ecu's,TPS check and set, cleaned as many connectors as possible, checked all fuses in both panels??????

 

Have not a clue what which direction to look in - auto box shifts sweet when you manually shift it???

 

Is this pointing towards auto ecu as mechanically the box seems fine and has been for the past 18 months.

 

HELP! :headvswal

Have you checked the tps readings on a conzult or similar, if the voltage is too high or low that will throw up a fault.

  • Author

I checked and set up the TPS with a multimeter but I suppose it could be reading high or low as the voltage is very small anyway. Maybe the meter is not sensitive or accurate enough at such low voltage??????

 

Would this make my car have these sort of gearbox probs though?

 

Thanks for the reply as they all help...........................hopefully.

 

Nice one.

 

Nigel
