Drive with caution — fix soon.
This code means the A/C refrigerant pressure sensor is sending a signal that's too high, often near full voltage. It usually points to a wiring short to power, a faulty sensor, or a genuinely overcharged or restricted A/C system. Most repairs involve replacing the sensor, fixing wiring, or correcting the refrigerant charge.
$120 – $380
Varies by vehicle and root cause.
Yes, in most cases. The fault is in the A/C system, so it won't affect engine safety or stop you from driving. Your cooling may be reduced or shut off, which is the main downside. Have it checked soon to avoid stressing the compressor.
Repairs typically range from $120 to $380. Swapping the sensor is the cheapest fix; correcting an overcharge or clearing a restriction in the lines costs more. A proper diagnosis ensures you only pay for what's actually wrong.
It's moderate. It won't damage your engine, but a real high-pressure condition can strain the A/C compressor and components. Getting it addressed protects the more expensive parts of the system.
Yes. An overcharged system raises pressure beyond normal, which the sensor reports as a high signal and sets this code. A shop can recover excess refrigerant and recharge to the correct amount to clear it.
