DTC 522617 Throttle Failed to Fully Open/Close
Conditions for Setting the DTC
Electronic Throttle Control
Check Condition-Ignition ON
Fault Condition-TPS 1 and 2 calculated values exceed 10%
MIL-On during active fault
Circuit Description
Dual throttle position sensors (TPS) are used with the electronic throttle control (ETC) to determine
throttle plate position. Although the actual voltage values between them are inverse, the calculated position
values should remain very close. The TPS values are used by the ECM to determine if the throttle is open-
ing and closing as commanded. This fault will set if the ECM detects more than a 10% difference in
calculated values between TPS 1 and TPS 2.
