Fuel Rail Pressure Sensor Circuit Bank 2

Where it lives

For P01BE, the circuit described runs through the sensor. The description of P01BE puts it on bank 2.

Check these first

• Bank 2 fuel rail pressure sensor unplugged or an open signal wire
• Corrosion or fuel in the bank 2 rail sensor connector
• A failed bank 2 rail pressure sensor element
• Low fuel pressure on the bank 2 rail
• ECM bank 2 rail pressure input fault after the wiring checks

What to do next

1. Check reference voltage and ground at the bank 2 rail pressure sensor
2. Inspect the bank 2 rail sensor connector for corrosion or fuel
3. Test the bank 2 rail sensor signal wire for opens and shorts
4. Read bank 2 rail pressure live data and compare to bank 1
5. Replace the bank 2 rail pressure sensor if the circuit tests good
6. Clear the code and retest
