Idle Speed, Current At Idle Speed Air Valve
Special Tools
Commercial Testers
Note:
Idle speed control is independent of air flow sensor potentiometer. Engine oil temperature approx. 80 °C, selector lever in position "P" or N", A/C
compressor switched off and no leaks in intake system. Idle contact, coolant temperature sensor and exhaust gas recirculation operating properly.
At high altitudes (>2000 m) current consumption may drop below 700 mA as the actuator requires to open a significantly greater cross section at such
altitudes to stabilize the engine.
Road speed signal
The test should only be performed if the following complaint is received: "Bucking when car running with closed throttle valve".
