Code P0662 Chrysler Description
The P0662 Chrysler diagnostic trouble code refers to an issue with the intake manifold tuning valve control circuit on bank 1 of the engine. This valve is responsible for controlling the airflow within the intake manifold, optimizing the engine's performance based on various driving conditions. When the control circuit is detected as having a high voltage, it indicates a malfunction in the system that could lead to poor engine performance, reduced fuel efficiency, and potential drivability issues.
Common Causes of P0662 Chrysler
- Faulty intake manifold tuning valve
- Wiring or electrical issues in the control circuit
- Corrosion or poor connections in the circuit
- PCM (Powertrain Control Module) failure
- Carbon buildup in the intake manifold
Symptoms of P0662 Chrysler
- Check Engine Light illuminated on the dashboard
- Reduced engine power or acceleration
- Rough idling or stalling
- Decreased fuel efficiency
- Engine misfires or hesitation during acceleration
How to Fix P0662 Chrysler
- Diagnose the issue using a scan tool to verify the P0662 code and identify the specific cause.
- Inspect the intake manifold tuning valve and related wiring for any visible damage or corrosion.
- Test the voltage and continuity of the control circuit to pinpoint the faulty component.
- Replace the intake manifold tuning valve or repair any damaged wiring as necessary.
- Clear the diagnostic trouble codes, reset the PCM, and perform a test drive to ensure the issue has been resolved.
Cost to Fix P0662 Chrysler

Frequently Asked Questions about P0662 Chrysler Code
1. What does the OBDII code P0662 mean for a Chrysler vehicle?
P0662 indicates a high voltage issue in the Intake Manifold Tuning Valve (IMTV) Control Circuit on Bank 1.
2. What are the common symptoms of a P0662 code in a Chrysler?
Symptoms may include reduced engine performance, poor fuel economy, hesitation during acceleration, and an illuminated Check Engine Light.
3. What causes the P0662 code to appear on a Chrysler?
Possible causes include a faulty intake manifold tuning valve, damaged or corroded wiring, a malfunctioning IMTV control solenoid, or a failed engine control module (ECM).
4. Can I drive my Chrysler with a P0662 code?
While the vehicle may still be drivable, driving with a P0662 code can lead to reduced engine performance and potentially cause long-term damage if not addressed.
5. How do I diagnose the P0662 code on a Chrysler?
Diagnosis typically involves inspecting the IMTV control circuit for damaged wiring, checking the IMTV solenoid for proper operation, and testing the voltage and resistance of the circuit.
6. How is the P0662 code repaired on a Chrysler?
Repairs may include replacing the intake manifold tuning valve, repairing or replacing damaged wiring, cleaning electrical connections, or replacing the ECM if necessary.
7. How much does it cost to fix a P0662 code on a Chrysler?
Repair costs can vary but typically range from $100 to $400 depending on whether the issue is with the IMTV valve, wiring, or ECM.
8. What tools are needed to fix the P0662 code on a Chrysler?
Tools may include an OBDII scanner, a multimeter for electrical testing, and basic hand tools for accessing and replacing components.
9. Can a dirty intake manifold cause a P0662 code on a Chrysler?
A dirty intake manifold is not a direct cause of the P0662 code, but buildup can affect the operation of the IMTV valve, contributing to performance issues.
10. Will clearing the P0662 code with a scanner fix the problem?
Clearing the code will reset the Check Engine Light temporarily, but the underlying issue must be repaired to prevent the code from returning.
