3 weeks after engine rebuild. Pass smog test. Next day, friday the 13th, service light comes on. Next day, check codes at autozone. Codes are tps and circuit heater{both banks}. Start motor after codes read. No service light. Are there any truth to these codes?? They have not come on since. So my next question is; does tps just stop working, or does it slowly die? Whats the difference on prices? What the one that everyone goes to?? No code, no worry??

 

It's a Land Rover. All codes come back eventually lol

 

Maybe check the connection is good, trace the wires back, but it may be starting to go.

 

TPS don't usually fail, CPS much more common. Codes will come back.

 

I know. I'm living a lie.
