Drive with caution — fix soon.
This code means the exhaust pressure sensor is sending readings that don't match expected exhaust conditions, so its values are outside the normal performance range. It usually points to a worn sensor, blocked or leaking sensor tubes, an actual exhaust restriction, or wiring issues. It's a moderate code tied to emissions and drivability and is generally fixable with a sensor or exhaust repair.
$150 – $450
Varies by vehicle and root cause.
Usually yes for a short time, but don't put it off. Out-of-range readings can affect EGR and emissions and may cause reduced power, so get it diagnosed within a few days.
Expect roughly $150 to $450. A sensor replacement or tube cleaning is on the lower end, while clearing an exhaust restriction or chasing wiring problems can push the cost higher.
It's moderate. The car typically stays drivable, but performance and emissions can suffer, and on diesels it ties into the particulate filter, so it shouldn't be ignored long term.
P0472 means the sensor is working electrically but its readings are out of the expected range, often due to a real exhaust issue or a drifting sensor, rather than a simple wiring short or open.
