Question 1

Where are the Camshaft Position Sensor(G40/G163) located and How to test them on Audi TT Quattro?

Accepted Answer

The camshaft position sensors on the 3.2L engine are on the left side of the cylinder head. G40 is for the intake camshaft and G163 for the exhaust camshaft. Unplug the harness connector from the camshaft position sensor and connect the test leads of the multimeter between terminal 1 (B+) and terminal 3 (ground). This would be the voltage supply (+) signal and ground (-). Start the ignition with a minimum specified value of 4.5 V. If the specification is not achieved, use the wiring diagram to check for open or short circuit in the wiring. If the specifications are no longer met and no wiring faults are found, replace the camshaft position sensor.

Question 2

Where is the Camshaft Position Sensor(G163) and what happens if it fails on Audi TT Quattro?

Accepted Answer

The 1.8L engines have the camshaft position sensor located on the cylinder head's right side. In the case of camshaft location sensor failure, knock control will be disabled and ignition timing slightly retarded because the control unit cannot assign signals to the cylinders. Also, charge pressure of the turbo will be decepted. The engine will work furthermore will restart without receiving a signal from the sensor. When a fault occurs, the engine control module will produce one spark per crankshaft revolution for each cylinder and the injection system may be one revolution out of phase, so that fuel is injected upstream of the closed inlet valve, which has a marginal effect on air/fuel quality. To test the sensor, pull back the rubber sleeve covering the harness connector. Connect the test leads of a LED voltage tester to terminal B and terminal A. Operate the starter motor briefly, the LED should flash. If the LED light doesn't turn on, check the voltage supply and signal with a multimeter connected to the harness connector terminals and engine ground. Supply voltage is about 5 volts, while signal voltage is battery voltage (12 volts). If specifications are not available, check the grounding wire for continuity and the wiring for open or short circuits. Should no faults be found but specifications are still not met, replace the camshaft position sensor.
