dk20: Service Code 66: Induce Opposite Code
| Steps | _Key OFF, wait 10 seconds
_Disconnect vehicle harness from Vane Meter _Install jumper wire in Vane Meter vehicle harness connector between VREF and VAF SIGNAL _Perform Key ON, Engine OFF Self-Test |
| Result | Is Code 56 present?
If no codes are generated, immediately remove jumper and GO to Continue |
| Direction | YES
Replace Vane Meter. Remove jumper wire. Reconnect Vane Meter. Rerun Quick Test NO Remove jumper wire GO to Continue |
| Notes | Disconnecting Vane Meter disconnects both VAF and VAT sensors. Code 58 should also be present. Disregard all codes except VAF codes at this time. |
| Component | Vane Airflow Meter |
| Description | The VAM measures air flowing into the engine. The meter contains a movable vane directly connected to a potentiometer.
Air, rushing through the VAM, changes the position of the vane and the potentiometer. The potentiometer relays vane position information to the EEC. The EEC can then translate vane position information into the volume of air flowing into the engine The VAM also contains an air temperature sensor. The sensor constantly monitors the temperature of the air flowing into the engine and reports the information to the EEC. The EEC computes volumetric airflow and air temperature, then adjusts the fuel flow to obtain the optimum air/fuel ratio. |
