Code P0653 Chrysler Description
The P0653 Chrysler diagnostic trouble code (DTC) refers to a 5 Volt Sensor Reference 2 Circuit High. This code indicates that the Engine Control Module (ECM) has detected a high voltage condition in the 5-volt sensor reference circuit 2. The 5-volt sensor reference circuit is used by various sensors in the vehicle to provide accurate readings to the ECM. When the voltage in this circuit exceeds the predetermined threshold, the ECM triggers the P0653 code.
Common Causes of P0653 Chrysler
- Faulty 5-volt sensor reference circuit
- Short circuit or open circuit in the wiring harness
- Corrosion or poor connections in the sensor reference circuit
- Defective Engine Control Module (ECM)
- Sensor malfunction affecting the sensor reference circuit
Symptoms of P0653 Chrysler
- Check Engine Light illuminated
- Erratic or rough engine operation
- Loss of power or acceleration
- Difficulty starting the vehicle
- Poor fuel efficiency
How to Fix P0653 Chrysler
- Begin by diagnosing the specific sensor causing the high voltage condition using a scan tool.
- Inspect the wiring harness for any signs of damage, corrosion, or poor connections. Repair or replace as needed.
- Test the sensor reference circuit for proper voltage levels and continuity. Replace any faulty components.
- Clear the DTC and drive the vehicle to ensure the code does not return.
- If the issue persists, consider replacing the ECM or consulting a professional technician for further diagnosis and repair.
Cost to Fix P0653 Chrysler
The cost of repairing a P0653 Chrysler code can vary depending on the specific cause of the issue and the labor rates in your area.

Frequently Asked Questions about P0653 Chrysler Code
What does the OBDII code P0653 mean for a Chrysler vehicle?
The P0653 code indicates that the 5 Volt Sensor Reference 2 Circuit is experiencing a high voltage issue, which means the voltage has exceeded the expected range.
What are common symptoms of the P0653 code?
Symptoms may include the Check Engine Light illuminating, poor engine performance, erratic sensor readings, and possible engine stalling.
What causes the P0653 code to appear?
Common causes include a short to voltage in the 5V reference circuit, a faulty sensor connected to the circuit, damaged wiring, or a malfunctioning Powertrain Control Module (PCM).
Can I drive my Chrysler with the P0653 code active?
While it may be possible to drive, it is not recommended as the code can cause engine performance issues and may lead to further damage if not addressed.
How is the P0653 code diagnosed?
A technician will use a scan tool to monitor sensor data, inspect the 5V reference circuit for wiring damage or shorts, and test sensors connected to the circuit for proper operation.
What sensors are typically connected to the 5V reference 2 circuit?
Sensors such as the throttle position sensor (TPS), manifold absolute pressure (MAP) sensor, and others may be connected to this circuit, depending on the vehicle.
How can the P0653 code be fixed?
Repairs may include fixing or replacing damaged wiring, replacing a faulty sensor, or reprogramming or replacing the PCM if it is determined to be defective.
Can a weak battery or alternator cause the P0653 code?
While unlikely, electrical system issues such as low voltage from a weak battery or failing alternator can potentially affect sensor circuits and should be checked.
What tools are needed to troubleshoot the P0653 code?
Basic tools include a scan tool, multimeter, and wiring diagrams to test voltage and continuity within the circuit and identify the fault.
How much does it cost to fix the P0653 code on a Chrysler?
The repair cost varies depending on the cause but typically ranges from $100 to $500, with sensor or wiring repairs being less expensive and PCM replacement being more costly.
