SERVICE INFORMATION
The adjustment procedure for the throttle position sensor (TPS) has been revised and standardized for all the Applied Vehicles.
^
The TPS contains a closed throttle position switch (CTPS) and a variable output throttle position sensor.
^
This procedure uses the closed throttle position switch (CTPS) status (ON or OFF) instead of the throttle position sensor (variable output voltage) to
adjust the TPS.
^
Incorrect adjustment of the CTPS may cause one or more of the following Diagnostic Trouble Codes (DTCs) to be displayed:
P1447, P0120, P0510, P0731, P0732, P0733, P0734, P1705.
SERVICE PROCEDURE
1.
Check fast idle cam (FIC) function, if equipped (refer to appropriate Service Manual). When finished, make sure the engine is at normal operating
temperature and the fast idle cam (if equipped) has released. Then turn the engine "OFF".
2.
Disconnect the harness connector (see Figure 1) from the closed throttle position switch (CTPS) position of the throttle position sensor (TPS).
3.
Connect an ohmmeter across the terminals for the closed throttle position switch (CTPS).
