P0549 Exhaust Gas Temperature Sensor Circuit High Bank 2 Sensor 1
Exhaust Gas Temperature Sensor Circuit High Bank 2 Sensor 1: the signal voltage is above the expected range. The ECU uses this temperature to protect the catalyst and diesel particulate filter.
Is it safe to drive with P0549?
Usually safe to drive in the short term. Get it diagnosed when convenient, sooner if the car drives differently.
Common causes
- Most likelySignal shorted to supply
- Less likelyConnector pins corroded - high contact resistance
- Less likelySupply wire pinched against B+ source
