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.
Low severity. Can I keep driving?You can normally keep driving. If it affects the fuel level, do not trust the gauge and refuel earlier than usual.
Symptoms
- Check engine light on
- Usually no noticeable symptoms
- Cold-start behaviour slightly affected possible
Most 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
What to check, in order
Start with the simplest. You can tick off each step.
Good to know
- Repair difficulty: medium
- It affects emissions.
What each character of P00E5 means
- P: Powertrain: engine and transmission
- 0: Generic code: same on every make
- 0: Subsystem depends on the code range
- E5: Specific fault in that system
Frequently asked questions
