DIAGNOSTIC NOTES
NOTE: Make sure nothing is touching or obstructing the accelerator or brake pedals during the TP SENSOR/IDLE LEARN procedure because
this will prevent the PCM from performing the learn routine.
NOTE: High electrical loads may disable TP SENSOR/IDLE LEARN. Components that may produce a high electrical load are the headlamps,
the rear defogger, high HVAC blower and the cooling fans. If difficulty is encountered learning TP SENSOR/IDLE LEARN values (i.e. Code
P080 remains current), turn "OFF" these high electrical loads. Also, it is important to accelerate the engine above 1000 RPM after turning "OFF"
the above components because the PCM will think it is still under a high electrical load until it checks the system again (when engine rpm exceeds
1000 RPM). Furthermore, since the cooling fans can not be manually controlled, engine coolant temperature must be below 105°C and A/C
refrigerant temperature must be below 510°C.
