If air mass specified is above 370, engine too cold. Operating condition right digit: AC compressor switched onĪir mass drawn in (specified): 230 - 370 mg/HĪir mass drawn in (actual): 230 - 370 mg/HĮGR vacuum solenoid duty cycle: 40 - 75 % Operating condition middle digit: Closed throttle position switch is closed (foot not on pedal) Operating condition left digit: 1 = idle increased because AC is on Throttle should go 0 - 100 depending on pressure applied to 'go' pedal If above 2.000 volts - injection is too lean, or engine is cold If below 1.450 volts - injection too rich If above 9.0 - injection is running too lean, or the engine is cold If below 2.2 - injection is running too rich Modulating piston displacement sensor voltage: 1.450 - 2.000 VĮngine coolant temperature sensor: 80 - 110 C These are valid ranges only when the EGR is switched on, engine at idle and at least 80C (176F) coolant temp. Intake Manifold Temperature: 182 - 50 = 10 - 110 degrees Cįuel Temperature: 91 - 201 = 20 - 80 degrees C Injection quantity: 11 - 45 = 2.2 - 9.0 mg/strokeĮngine coolant temperature: 80 - 35 = 80 - 110 degrees C Start of injection: range 12 - 75 = 2 degrees ATDC - 3 degress BTDC Actual labels/values displayed may vary.Įngine idle speed: range 42 - 45 = 870-950 Based on the Bentley CD but includes other groups not documented there.
