tps % fluctuating

Recommended Posts

I have just finished the install of a silver extreme on a 2jz-gte and the tps on pc link seems very eratic. I set tps and it seems to fluctuate between 0% and 7% with the throttle closed I have tried adjusting it and re setting it but it still fluctuates also when u open the throttle slowley it dosnt seem to be smooth on the graph engine runs fine but trying to get all the little things sorted before the dyno. maybe worn tps?

Hi Matt

All the fault codes can be found in the Help file of PC link. (it is a rather long list)

Check the ground and power supplies to the TPS are stable. If either of these change then it will effect the TPS reading.
