Checking The Status

Check whether the fault is permanent or intermittent by reading the signals from the fuel, outside and engine temperature sensors.

• Start the engine.

Check that the intake temperature is reasonable. The temperature must correspond to the ambient temperature.

The fault is permanent if the signal is incorrect. The fault is intermittent if the signal is correct.

HINT: Remove the air temperature sensor, but let the connector remain connected. Let the hood remain open, the sensor should then indicate the same temperature as the outdoor temperature.
