P00E5 Intake Air Temperature/Fuel Temperature Correlation
Check engine lightOn
EmissionsRelevant
Drive cycleRequired
Limp modeNo
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.
Likely causes
Fuel or intake air temperature sensor drifting
Block heater, sunshine, very warm or cold fuel from refuelling, or a short standstill
Contact resistance at a connector
Engine control module or software
Symptoms
- Check engine light on
- Usually no noticeable symptoms
- Cold-start behaviour slightly affected possible
