Conditions for Setting the DTC

Throttle Position Sensor

Check Condition-Cranking or Running

Fault Condition- TPS 1 and TPS 2 signals simultaneously out of range

MIL-On during active fault

Engine shutdown
Circuit Description
Dual throttle Position Sensors are used within the throttle that use variable resistors to deter-
mine signal voltage based on throttle plate position. TPS 1 will read low voltage when closed
and TPS 2 will read high voltage when closed. The TPS 1 and TPS 2 percentages are calcu-
lated from these voltages. Although the voltages are different, the calculated values for the
throttle position percentages should be very close to the same. The TPS values are used by
the ECM to determine if the throttle is opening as commanded. This fault will set if the TPS 1
and TPS 2 signal voltages are simultaneously out of operational voltage ranges. The MIL
command is ON and the engine will shutdown.
