OBD2 check engine codes for Chrysler

Chrysler products use the Pentastar 3.6L V6 and older 3.5L V6, both of which have documented OBD2 failure patterns around cam timing, oil sludge, and EVAP systems. Repair costs are generally on par with other domestic brands.

Select a code below for Chrysler-specific causes, affected models, and repair cost estimates.

Frequently asked questions

What are the most common check engine codes for Chrysler?

The most frequently seen OBD2 codes on Chrysler vehicles include P0420 (catalyst efficiency), P0171 (system lean), P0300 (random misfire), P0128 (coolant below thermostat temperature), and P0442 (EVAP small leak). Select any code above for Chrysler-specific causes and repair guidance.

Can I diagnose Chrysler OBD2 codes myself?

Yes. A basic Bluetooth OBD2 scanner ($20–$40) paired with a free app will read all standard P-codes on any Chrysler. For manufacturer-specific codes or advanced system faults, a professional scan tool provides more detail. Most auto parts stores will also read codes for free.

How much does it cost to fix a check engine code on a Chrysler?

Repair costs vary widely by code and model. Simple fixes like a loose gas cap or a sensor replacement run $20–$150. Moderate repairs such as an oxygen sensor, thermostat, or ignition coil typically cost $150–$400. Major repairs like a catalytic converter or transmission component can run $500–$2,500 or more. Each code page includes a specific cost range.

Is it safe to drive a Chrysler with the check engine light on?

It depends on the code. Many codes—like EVAP leaks or minor sensor faults—are safe to drive with for a few days. A flashing check engine light or codes related to misfires, oil pressure, or overheating require stopping immediately. Look up your specific code for a direct answer.
