Ok, ran the ECU diagnosis this morning, and just want to clarify before I go changing out parts all willy-nilly.

1. Code 13 - CHTS. I will replace soon.

2. Code 23 - Throttle Valve Switch/Idle Switch. I have my idle turned almost all the way up to keep the car from stalling at startup, but that shouldn't throw the code 23. Does Throttle Valve Switch mean the same as TPS? Can it be adjusted, or should I replace?

3. Code 41 - Fuel Temp Sensor. Where is this located? Is it the sensor included with the FPR? I've already replaced the FPR (which comes with a sensor attached). Looks like the previous owner jerry-rigged the wire going to that sensor with longer wire, a crimped barrel connector for the wire and a spade connector to the sensor.

Thanks in advance for the responses.

Thanks much. That's where the shoddy wire extension was done by the mechanic. I'll re-do it in the morning if I can find a spade connector in my toolbox, tomorrow evening if not.

Any ideas on the Throttle Valve Switch? same as TPS?
