P1220 NISSAN - Fuel Pump Control Module
P1220 NISSAN Possible Causes
- Faulty Fuel Pump Control Module (FPCM)
- Fuel Pump Control Module (FPCM) harness is open or shorted
- Fuel Pump Control Module (FPCM) circuit poor electrical connection
- Faulty dropping resistor
How do I fix code P1220 NISSAN?Check the "Possible Causes" listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector's pins.
Cost of diagnosing the P1220 NISSAN code
Labor: 1.0The cost of diagnosing the P1220 NISSAN code is 1.0 hour of labor. The auto repair labor rates vary widely across the country, and even within the same city. Most auto repairs shops charge between $75 and $150 per hour.
When is the code detected?An improper 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 Engine Control Module (ECM).
- Engine Light ON (or Service Engine Soon Warning Light)
P1220 NISSAN MeaningThis system controls the fuel pump operation. The amount of fuel flow delivered from the fuel pump is altered between two flow rates by the Fuel Pump Control Module (FPCM) operation. The FPCM determines the voltage supplied to the fuel pump (and therefore 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 is decreased.
