Throttle Valve Intake Air Pressure Sensor Circuit Low

Where it lives

For P2EB1, the circuit described runs through the sensor. The description of P2EB1 reports a fault at the sensor.

Check these first

• A short to ground on the intake air pressure sensor signal
• A failed intake air pressure sensor
• A vacuum leak at the throttle valve sensor port
• High resistance in the sensor wiring
• A corroded sensor connector

What to do next

1. Read throttle valve intake air pressure on a scan tool
2. Compare the reading to barometric pressure with the engine off
3. Test the sensor signal for a short to ground
4. Check the sensor port for a vacuum leak
5. Replace the intake air pressure sensor if the circuit tests good
6. Clear the code and retest
