Drive with caution — fix soon.
This code means the computer detected a problem in the air conditioning refrigerant pressure sensor circuit. It's typically caused by a faulty A/C pressure sensor, wiring or connector issues, or sometimes incorrect refrigerant charge. Replacing the pressure sensor, repairing wiring, or correcting the refrigerant level usually fixes it.
$120 – $400
Varies by vehicle and root cause.
Yes, it's safe to drive. This code only affects the air conditioning system, not engine operation, so the main downside is that your A/C may not cool properly.
Repairs typically range from $120 to $400. Replacing the A/C pressure sensor is usually affordable, while wiring repairs or refrigerant service can add to the total.
It's a low-to-moderate concern. It won't harm your engine, but it can leave you without working air conditioning, so it's worth fixing for comfort, especially in hot climates.
The system often disables the A/C compressor when it can't trust the refrigerant pressure reading, as a protective measure. Fixing the sensor or wiring usually restores normal cooling.
