Monitored & Set Conditions

Fuel level is monitored in 2 tests. Test one is with ignition on. The fuel level is compared to the previous key down after a 20 second delay. Test 2, the PCM monitors the fuel level at ignition on. In test one, if the PCM does not see a difference in fuel level of greater than 0.1 volt with ignition on, the test will fail. In test 2, if the PCM does not see a change in the fuel level of 0.1765 volt over a set amount of miles, the test will fail. This is a two trip fault.
