Error code
OBD2 P0182
OBD2P0182
Diagnostic Trouble Code· Standard OBD-II fault code read from the vehicle's onboard diagnostics.
What it means
Fuel Temperature Sensor A Circuit Low.
Severity
moderateCan drive, but expect poor performance and fuel economy.
Summary
P0182 indicates that the fuel temperature sensor A is reporting an abnormally high temperature to the ECM due to low input voltage.
Symptoms
- Poor fuel economy
- Hard starting
- Poor performance
Common Causes
- Wiring problems such as water entry, corrosion, or wire harness damage.
- Faulty fuel temperature sensor (FTS) or ECM due to water entry or collision damage.
Diagnosis
- Check for proper resistance across the two pins of the ECM connector.
- Inspect wire harness for bent pins or corrosion; repair as necessary.
- Test FTS directly by measuring its resistance and comparing it to the manual's chart.
Fixes
- Replace faulty wiring, connectors, or fuel temperature sensor.
FAQ
What should I do if my MIL is on and P0182 is set?
Start by checking the wiring harness for any signs of damage or corrosion. If issues are found, repair them. Otherwise, test the fuel temperature sensor directly.
