Exhaust Gas Re-circulation Position Sensor Circuit High
There's an issue with the EGR position sensor signal being too high.
Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.
What it means (plain English)
The computer thinks the EGR valve position is more than it should be, which can cause emission issues and can affect engine performance.
What the computer is actually seeing
The EGR position sensor is reporting a voltage that is too high, typically above 4.5 volts when it should be between 0.5 and 4.5 volts for proper operation.
What a healthy reading looks like
EGR position sensor voltage should range from 0.5 to 4.5 volts. Any value higher than 4.5 volts or less than 0.5 volts indicates a fault.
Guided diagnostic — the DiagCoach way
Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.
- 11. Check the EGR position sensor connector for damage, corrosion, or loose connections. Repair as necessary.
- 22. Using a multimeter, measure the voltage at the EGR position sensor while the engine runs. It should be between 0.5 to 4.5 volts. If it’s above 4.5 volts, proceed to step 3.
- 33. Inspect the wiring between the EGR sensor and the ECM for shorts to power. Repair any issues found.
- 44. If the wiring is good, replace the EGR position sensor. Re-check voltage after replacement.
Common causes
- Faulty EGR position sensor
- Wiring harness short to voltage
- Corroded or poor connections at the EGR sensor
- Faulty EGR valve
- ECU programming error
Typical repair cost
$$$ ($200 - $600)
