TPS trouble codes 12 and 18 help
TPS trouble codes 12 and 18 help
Are my tps resistance readings bad? My tps resistance readings on the bottom if you don't want read everything
91 n/a manual transmission
I just swapped in an engine with lower miles and starts up fine, but the idle constantly goes high and low between 1000rpm-2000rpm
I checked all hoses and intake gaskets with a bottle of carb cleaner and there are no leaks causing this
but once the engine warms up it goes to about 800rpm
i then checked for codes and found code 12 and 18
so i adjusted the tps fully warmed up and it was a bit off but not by much
it was at about 1500k so I adjusted to about 980-1000k with the car off
start the car warm again and everything is fine,
but once i start the car cold it does the same idle goes high and low between 1000rpm-2000rpm and still have the trouble codes
* i checked the tps for resistance cold and it has
Narrow Range full throttle is 7.40k should be 4.0-6.0k
Narrow Range closed is .486k should be 0.8-1.2k
edit:forgot to add full range readings
Full Range full throttle is 8.91k should be 3.4-5.1k
Full Range closed is 80.0k should be 0.6-0.9k
since the resistance readings are off then i should be looking for a working tps
I need to double check the cam roller and thermowax but im sure its in the right adjustment
