EGR Temperature Sensor Out Of Range
EGR temperature sensor is reporting outside expected temperature limits.
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 EGR temperature sensor measures the exhaust gas temperature going into the intake. When it reads too high or too low, the system thinks there's a problem with the EGR operation.
What the computer is actually seeing
The Engine Control Module (ECM) sees EGR temperature readings that fall outside of the normal range, generally between 100°C to 400°C (212°F to 752°F).
What a healthy reading looks like
EGR temperature readings should typically be between 100°C (212°F) and 400°C (752°F).
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 wiring and connectors for the EGR temperature sensor for damage or corrosion. Repair if necessary. Decision: If wiring is good, move to step 2.
- 22. Measure the EGR temperature with a scan tool or multimeter. Compare it to the expected values of 100°C to 400°C. Decision: If it’s out of range, move to step 3. If it's in range, consider a possible ECM issue.
- 33. Inspect the EGR valve operation. Look for excessive carbon buildup or mechanical failure. Test the EGR valve with a vacuum or electrical test. Decision: If the valve is malfunctioning, replace it. If it operates correctly, replace the temperature sensor.
Common causes
- Faulty EGR temperature sensor
- Wiring or connectors damaged
- EGR valve malfunction
- Exhaust leaks affecting temperature readings

Frequently asked questions
Is it safe to drive with SPN 4113?
It's not recommended to drive long distances as it may affect emissions and lead to further engine problems.
Will this code come back after clearing it?
If the underlying issue isn't fixed, it will likely return after a few cycles.
Why does SPN 4113 show up with other EGR codes?
EGR-related codes often appear together because they stem from the same system malfunctions.
