Powertrain Codes

P0182 - VOLKSWAGEN - Fuel Temperature Sensor A Circuit Low Input

Symptoms

- Engine Light ON (or Service Engine Soon Warning Light)

Possible Causes

- Harness or connectors (The sensor circuit is open or shorted) - Fuel tank temperature sensor may be faulty

When Detected

An excessively low voltage from the sensor is sent to ECM.

Description

The fuel tank temperature sensor is used to detect the fuel temperature inside the fuel tank. The sensor modifies a voltage signal from the ECM. The modified signal returns to the ECM as the fuel temperature input. The sensor uses a thermistor which is sensitive to the change in temperature. The electrical resistance of the thermistor decreases as temperature increases..
