Frequently Asked Questions
What does P2573 mean?
P2573 means the turbocharger boost pressure sensor is reading higher than the maximum expected voltage, which could indicate a wiring short or sensor failure.
Can I drive with a P2573 code?
Drive only short distances. A high reading could mask an actual overboost condition, which can cause serious engine damage.
How much does it cost to fix P2573?
Repairs typically cost $200 to $500. Wiring repair is on the lower end, while sensor replacement is $250 to $400 with labor.
