P0182 Quick Answer
Fuel temperature sensor voltage is below the expected minimum — typically a short to ground or open signal.
What Does P0182 Mean?
Fuel Temperature Sensor "A" Circuit Low Input. Fuel temperature sensor voltage is below the expected minimum — typically a short to ground or open signal.
Symptoms
- Check engine light
- Fuel temperature reading at the low limit (typically -40 °C / -40 °F)
Common Causes
- Short to ground on the signal wire
- Failed sensor stuck low
- Connector damage
Diagnosis Steps
You’ll need a scan tool capable of reading live powertrain data, a digital multimeter, and access to the wiring diagram for the specific platform.
- Disconnect sensor and measure signal wire voltage at the harness — should rise to 5 V with sensor disconnected.
- If voltage stays at zero with sensor disconnected, the wire is shorted to ground.
- Resistance-check the sensor against spec.
Possible Fixes
- Repair shorted signal wire
- Sensor replacement
Can I Still Drive With P0182?
The vehicle will usually still drive with P0182 stored, but performance, drivability, or emissions will be degraded. The PCM may inhibit emissions monitors and limit closed-loop fueling adjustments. Drive to a workshop, but don’t ignore the code long-term — degraded sensor data can mask other faults and shorten catalyst life.
How Serious Is This Code?
P0182 is a moderate-priority fault. It will not prevent the engine from running but unaddressed it can damage the catalytic converter, reduce fuel economy, or cause failed emissions testing. Address within a few drive cycles.

FAQ
Will P0182 clear itself?
Only if the underlying fault was intermittent and self-corrected. Most root causes are persistent and require physical repair.
Can I clear P0182 without fixing it?
You can clear it with a scan tool, but it will return as soon as the fault condition reappears — typically within one or two drive cycles.
Is P0182 related to other codes?
Often, yes. Adjacent codes in the same circuit or system frequently set together — if P0182 is present, scan for related codes and address them as a group.
