SYMPTOM
There is low engine power or intermittent hesitation during acceleration, and/or the MIL light comes on with one or more of these PGM-FI DTCs:
^ P2122 - Accelerator Pedal Position (APP) Sensor A (Throttle Position [TP] Sensor D) Circuit Low Voltage
^ P2127 - Accelerator Pedal Position (APP) Sensor B (Throttle Position [TP] Sensor E) Circuit Low Voltage
^ P2138 - Accelerator Pedal Position (APP) Sensor NB (Throttle Position [TP] Sensor DIE) Incorrect Voltage Correlation
^ VSA DTC 83-13 - PCM Communication Error (Engine Malfunction)
^ VTM-4 DTC 77-1 - Functional Abnormalities of Fuel Emission System or the Automatic Transmission
PROBABLE CAUSE
The APP sensor connector lock tab does not hold the connector together.
CORRECTIVE ACTION
Inspect the APP sensor connector, and if necessary, secure it with a wire tie.
NOTE:
When the connector was originally connected, the plastic lock tab may not have been fully engaged. This would have caused the lock tab to set in the open position. Once the lock tab is used with a wire tie holding it in the locked position, the tab will set in the locked position. If the connector needs to be removed for service, the wire tie can be cut and discarded.
