Details of the Chrysler p0653 OBD Code
Code P0653 in a Chrysler indicates a sensor reference voltage ‘B’ circuit high.
Code P0653 for Chrysler vehicles means Sensor Reference Voltage B Circuit High.
This code is triggered when the Powertrain Control Module (PCM) detects that the sensor reference voltage B circuit voltage is higher than the normal operating range.
The sensor reference voltage B circuit is typically used to power various sensors in the vehicle, such as the throttle position sensor or the manifold absolute pressure sensor.
When this circuit voltage is too high, it can lead to improper sensor operation and affect engine performance.
Mechanic’s Tech Notes
P0653 code indicates a malfunction in the sensor reference voltage circuit for Chrysler vehicles.
To diagnose and fix OBDII code P0653 in a Chrysler vehicle, start by checking the Transmission Control Module (TCM) power and ground using a multimeter.
Ensure proper voltage levels are present.
Use a scan tool to confirm TCM communication over the Controller Area Network (CAN) network.
If no communication is detected, reprogramming or reflashing the TCM may be necessary.
Additionally, inspect the wiring harness and connectors for any damage, and check for broken, bent, or corroded pins.
Address any issues found during the visual inspection to resolve the P0653 fault code.
