P1220 GMC Meaning

The throttle position sensor (TP) is mounted on the throttle body of the throttle actuator control (TAC) assembly. The sensor is actually 2 individual throttle position sensors in 1 housing. Two separate signal circuits, one low reference circuit and one 5-volt reference circuit are used to connect the TP sensor assembly and the TAC module. The TP sensor signal voltage increases as the throttle opens. The TP sensor signal circuit is pulled up to a 5-volt reference voltage.

When is the Code Detected?

An incorrect voltage signal from the Fuel Pump Control Module (FPCM), which is supplied to a point between the fuel pump and the dropping resistor, is detected by the Engine Control Module (ECM).

Possible Symptoms

• Engine Light On (or Service Engine Soon Warning Light)

P1220 INFINITI Meaning

This system controls the operation of the fuel pump. The amount of fuel flow delivered by the fuel pump is changed between two flow rates by the operation of the Fuel Pump Control Module (FPCM). The FPCM determines the voltage supplied to the fuel pump (and thus the fuel flow) according to the following conditions.
The FPCM adjusts the voltage supplied to the fuel pump to control the amount of fuel flow. When the FPCM increases the voltage supplied to the fuel pump, the fuel flow is increased. When the FPCM decreases the voltage, the fuel flow decreases.
