Oct. 30 2020

Vehicle: 2019 Dodge Grand Caravan, V6-3.6L

Mileage: 15,667

Problem: The vehicle was in a body shop having repairs done to the left front area. After the body repairs were completed, the engine hesitated, bogged on acceleration and the malfunction indicator light (MIL) was On.

Case Details: When the body shop tech connected the scan tool, he found DTC P2127 - Accelerator Pedal Position (APP) Sensor 2 Circuit Low. He checked to make sure all related fuses had battery voltage. No fuses were open or missing. At that point, he made a quick call to ALLDATA Tech-Assist for some advice.

The Tech-Assist consultant suggested checking the APP, PCM and throttle body connectors and harness wires for damage, water intrusion, corrosion and poor terminal pin connections. He also suggested checking APP connector 12010A and the harness located in the left front of the vehicle because they may have been damaged in the collision.

The tech inspected connector I2010A and found the APP sensor ground circuit (K400) wire (BN/VT), (Pin 7) was broken between the connector and the APP sensor.
