...including Checking the specification of the engine), they were correct. I then tested the very short plug lead of No.4 for resistance which was within tolerance of 1-5 KOhms. As I had already removed No.4 plug lead, I then removed No.1 plug lead and checked the secondary winding resistance...

...ious ways:Checking current potential• Pull the plug from the air mass sensor.• Turn on the ignition.• Measure current on the plug.Note:The following electrical potential should be there (see illustration: Connectorassignment):• between pin 2 and vehicle ground: 12 Volt (vehicle...

...sting and Checking 20Step-by-step defect identification 21 Self-test 22Fewer emissions, lower fuel consumption, higher ignition voltage, restricted space in the drive unit and engine compartment: The design demands on modern ignition coils are constantly increasing. Although the t...

...roblem by Checking the fuel system. Fuel pressure and fuel flow measurements came back perfect. MAF signals were checked against known good values, a MAF Calculator was used to confirm air consumption figures. As a last check, we checked the injector opening duration on acceleration. Th...

...The OBD detects a malfunction, but does not always identify the actual cause. You should first check the old sensor before Installing a new air mass sensor based on an error message which points to the air mass sensor as the cause. In this video, we show you how to check conventional, anal...

...mfortable Checking the mechanical bits first. Fortunately, that’s where most problems lie. For this you are going to need a vacuum gauge and vacuum pump, or in the case of motorised actuators, a scan tool. Apply a vacuum to the actuator diaphragm. There should be a “clunk&rdquo...

...includes Checking the fuel supply. the following checkpoints are useful in this area: ➔ amount of fuel in the tank ➔ Tank ventilation system ➔ fuel quality (impermissible mixing of gasoline or biodiesel, for example, can lead to disruptions in the pump functions) ➔ fuel filter an...

...tly. On Checking the circuit diagram for the brake light switch, a link was noticed to the ABS ignition power supply. A quick load test at the ABS module revealed a volt drop on that circuit. Further investigation revealed the root cause of all the issues: Water damage to the switching...
