Drive with caution — fix soon.
This code means the A/C refrigerant pressure sensor is sending a reading that doesn't match what the computer expects for the current conditions. It usually points to a faulty pressure sensor, wiring problems, or sometimes an actual refrigerant charge issue. It's often fixable by replacing the sensor or repairing a connector, without major work.
$120 – $350
Varies by vehicle and root cause.
Usually yes. This code affects the air conditioning system, not the engine or brakes, so it's safe to drive. The main inconvenience is that your A/C may cool poorly or stop working. Get it looked at when convenient, especially before hot weather.
Most repairs run between $120 and $350. A simple sensor replacement is on the lower end, while wiring repairs or a refrigerant recharge can push the cost higher. A proper diagnosis first will keep you from paying for parts you don't need.
It's not serious for engine health or safety, so it ranks as moderate. The bigger concern is comfort and protecting your A/C compressor from running under wrong pressure readings. Fixing it sooner avoids potential compressor strain.
It can. If the refrigerant level is off, the sensor reads pressures outside the expected range, which triggers this code. A shop can check the charge and the sensor together to pinpoint whether it's a leak or a faulty sensor.
