P2024
EVAP Fuel Vapor Temperature Sensor Circuit
Evaporative emissions (EVAP)
Generic OBD-II
Low
What it means
P2024 sets when the PCM sees an out-of-range or faulty signal from the EVAP fuel-vapor temperature sensor circuit. This sensor helps the evaporative-emissions system monitor fuel-vapor conditions in the tank or canister. The fault is electrical — a bad sensor, wiring, or connector — and doesn't affect how the engine runs, but it will trip the check-engine light.
Low
Can I keep driving? Yes — no effect on how the car runs; it mainly disables an emissions monitor and can cause an emissions-test failure.
Common symptoms
What you'll notice
- Check-engine light on
- Failed or incomplete EVAP / emissions monitor
- No noticeable change in how the engine runs
Common causes
Most likely first
- Faulty EVAP fuel-vapor temperature sensorLikely
- Open or shorted wiring in the sensor circuitCommon
- Corroded or loose connector at the sensorCommon
- Failed PCM (rare)Less often
How to diagnose & fix
Work through it in order
- Scan freeze-frame and confirm the code.
- Inspect the sensor's connector and wiring for opens, shorts, or corrosion.
- Measure the sensor's resistance or signal voltage against spec.
- Replace the vapor-temperature sensor if it's out of range.
- Clear the code and run an EVAP monitor drive cycle to confirm the repair.
FAQ
Quick answers
Is it safe to drive with P2024?+
Yes. This is an emissions-monitoring sensor with no effect on drivability. The main consequence is a check-engine light and a possible emissions-test failure.
Can I just clear P2024?+
It comes back if the sensor or wiring is faulty. Repair the circuit, then clear it and complete a drive cycle.
