Vacuum Reservoir Pressure Sensor Circuit

Where it lives

For P2525, the circuit described runs through the sensor. The description of P2525 reports a fault at the sensor.

Check these first

• A failed vacuum reservoir pressure sensor
• An open or short in the sensor circuit
• A backed out pin at the sensor connector
• Low battery voltage

What to do next

1. Read the vacuum reservoir pressure sensor on a scan tool
2. Test the sensor circuit for open and short faults
3. Check the sensor connector pins
4. Check battery voltage under load
5. Replace the vacuum reservoir pressure sensor if the circuit tests good
6. Clear the code and retest
