FuelSeverity Low: usually safe to drive

P0183Fuel Temperature Sensor "A" Circuit High

What it means

The fuel temperature sensor signal voltage is too high. For this type of sensor that means the ECU sees an impossibly low temperature (about −40 °C), usually because the circuit is open. The ECU uses fuel temperature to correct the injected quantity (fuel gets thinner when hot).

Symptoms

  • Check engine light
  • Possibly slightly reduced power or harder hot starts

Common causes

  • Open signal or ground wire
  • Unplugged or corroded connector
  • Open circuit inside the sensor

What to check first

  1. Live data shows about −40 °C
  2. Bridge the connector terminals with a jumper: the reading should jump to a very high value
  3. Measure the sensor resistance (OL means it is open)
Can I drive with P0183? Usually yes. P0183 rarely affects how the car drives, but it keeps the check engine light on and can fail an emissions test.

Generic OBD-II meaning. Manufacturer-specific meanings and checks can differ; always check the service information for the car.
