B1220 code definition

The B1220 trouble code indicates an incomplete (or "open") circuit has been detected in your 2008 Saturn Vue 's fuel tank pressure sensor.

What the B1220 code means

The fuel tank pressure sensor detects leaks in the tank and aids your 2008 Saturn Vue 's Evaporative Emissions (EVAP) system in vaporizing fuel to help lower pollution. In the case of an incomplete pressure sensor circuit, this system will be weakened.

Faulty, disconnected or damaged wiring is most often the case for an incomplete sensor circuit. The fuel tank pressure sensor circuit itself may be faulty. If this is the case, it should be promptly replaced.

What are the symptoms of the B1220 code?

The B1220 code typically results in harsher exhaust and engine noise, a stronger gas smell when the engine is active, decreased fuel efficiency and the sensor's inability to regulate and report issues with fuel vapour in the fuel tank. A B1220 trouble code will be logged on your 2008 Saturn Vue 's diagnostic computer and a check engine lamp will be illuminated to alert your 2008 Saturn Vue operator to the problem.
