EVAP Fuel Vapor Temperature Sensor Circuit Low Voltage

Moderate severity

What it means

The EVAP fuel-vapor temperature sensor signal sits below the lower plausibility limit — short to ground or short between signal and ground inside the sensor.

Is it safe to drive?

Use caution

The vehicle is usually drivable for short distances, but the problem can worsen or affect emissions. Diagnose and repair as soon as practical.

Most likely causes

  • Short to ground on signal line

    high

    One of the most commonly reported causes for this code — check this first.

  • Connector pins corroded - high contact resistance

    low

    Less common, but worth ruling out after the more likely causes.

  • Harness chafing through insulation

    low

    Less common, but worth ruling out after the more likely causes.
