P00E5Intake Air Temperature/Fuel Temperature Correlation
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Needs a drive cycle to confirm a fix
- How the car detects it
- After a long standstill, intake air and fuel should be at about ambient temperature. This code is set when the intake air and fuel temperature sensors differ too much at the next start; it does not say which sensor is wrong. A detected engine block heater usually suspends the test. One manufacturer performs the same comparison under another code; who uses this exact code could not be documented.
- What you may notice
- Check engine light on
- Usually no noticeable symptoms
- Cold-start behaviour slightly affected possible
- Likely causes
- LikelyFuel or intake air temperature sensor drifting
- PossibleBlock heater, sunshine, very warm or cold fuel from refuelling, or a short standstill
- PossibleContact resistance at a connector
- RareEngine control module or software
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
