EGR Sensor E Circuit
A circuit fault is detected on the fifth exhaust-gas recirculation sensor (E). The ECU loses this EGR feedback channel and falls back to a substitute value; emissions and EGR rate accuracy on this stage are reduced until repair.
Affected components
- Egr sensor e
- Egr sensor wiring e
Common causes
- High likelihood: Open in sensor signal, supply or ground
- Medium likelihood: Connector corroded or contaminated
Possible symptoms
- Check engine light on
- Pinging or knocking under load
- Power loss and hesitation
- Possible rough idle
- Failed emissions inspection (NOx)
Diagnostic notes
- The malfunction indicator lamp may illuminate
- This code can affect emissions
