P2C82AIR System Pump Supply Voltage Circuit Bank 1
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Needs a drive cycle to confirm a fix
- How the car detects it
- P2C82 points to a fault in the supply voltage circuit of the bank 1 secondary air pump. Conventional pumps are switched on by a relay; pumps with their own electronics, like the brushless design in an FCA patent, receive a feed and can judge whether the voltage arriving there is plausible. No manufacturer documents P2C82 publicly; CARB demands that all electrical secondary air components be checked for circuit faults. Common causes are the high-current fuse, a corroded or loose connector, a damaged feed or ground wire and a relay with burnt contacts; heavy voltage dips during cranking may contribute. Without a proper feed the pump stays off, cold-start emissions rise and the secondary air readiness test fails. P0418 covers the relay control circuit, P2445 a pump that does not deliver.
- What you may notice
- Check engine light
- No pump noise for the first minute after a cold start
- Secondary air readiness incomplete
- Likely causes
- LikelyBlown high-current fuse for the pump
- PossibleRelay with burnt or sticking contacts
- PossibleCorroded or loose pump connector
- PossibleDamaged feed or ground wire to the pump
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
