4.TP SENSOR OPERATION
Ignition on, engine not running.
With a scan tool, perform the Throttle Follower Test.
TP Sensor No.1 should start at approximately 0.8 of a volt and increase to 4.2volts.
TP Sensor No.2 should start at approximately 4.2 volts and decrease to 0.8 ofavolt.
Is the voltage transition smooth between the appropriate values?
Ye s>>
Refer to the INTERMITTENT CONDITION Diagnostic Procedure.

Go To 5

When Monitored:
Ignition on and engine running with no MAP Sensor DTCs.
Set Condition:
PCM calculated MAP value is greater than actual MAP value plus an offset value. One trip fault and the code
will set within 5 seconds. Three good trips to turn of the mil. ETC light willflash.

Diagnostic Test
1.ACTIVE DTC
NOTE: The most likely cause of this DTC is a plugged intake air system or dirty Throttle Body. Check for
any TSB’s before continuing.
NOTE: Diagnose any 5-Volt Supply, TP Sensor, Oxygen Sensor, Fuel related or MAP Sensor DTCs before
continuing.
NOTE: The throttle plate should be free from binding and carbon build up.
NOTE: Question the customer about weather conditions, as ICE build up on the blade can cause this fault
when ambient is around +4 to -10 Celsius range.
Ignition on, engine not running.
With a scan tool, read DTCs.
Is the DTC active at this time?
