P0180 Code: Fuel Temperature Sensor A Circuit Malfunction
🟢 Low severity · drivable
Safe to drive. The fuel temperature reading is missing, which may slightly affect cold starts and fuel economy.
What P0180 means
The fuel temperature sensor A tells the computer how warm the fuel is so it can adjust fuel delivery and cold-start behavior. This code means the sensor's circuit has a fault, so the computer has no fuel temperature reading. The computer falls back on a default value, which can make fuel mixture slightly off.
Symptoms
- Check engine light is on
- Possible hard cold start
- Slightly worse fuel economy
- Usually no noticeable driving symptoms
Common causes
- most common: Faulty fuel temperature sensor
- common: Damaged wiring or connector at the sensor
- less common: Corroded connector pins
- rare: Faulty engine computer (PCM)
How to fix it
| Fix | DIY? | Typical cost |
|---|---|---|
| Replace the fuel temperature sensor | Yes | $40–150 |
| Repair or replace damaged wiring and connectors | Yes | $10–60 |
Frequently asked questions
Can I drive with a P0180 code?
Yes. It's a sensor reading issue and won't leave you stranded, though cold starts may be slightly harder.
What does the fuel temperature sensor do?
It measures fuel temperature so the computer can adjust fuel delivery and cold-start behavior for the current conditions.
What is the most common cause of P0180?
A faulty fuel temperature sensor, with damaged wiring close behind.
