Function: The DPFE sensor measures the difference in air pressure between the exhaust manifold and the intake manifold. This information is used by the engine's computer to adjust the air/fuel ratio and ignition timing.
Symptoms of a faulty DPFE sensor:
- Check engine light on
- Engine hesitation or stalling
- Decreased fuel efficiency
- Black smoke from the exhaust pipe
- Rough idling
Replacing the DPFE sensor is relatively easy and inexpensive. It is a good idea to replace the sensor if you experience any of the above symptoms.
