    How to Replace an audi replacement key cost G28 Engine Speed Sensor

    In this video, Charles the humble mechanic demonstrates how to replace the G28 engine speed sensor. This sensor is located at the edge of transmission over the flywheel gear. It transmits a signal the ECU via a grey wire (T55/49) which is then sent to the tachometer within the instrument cluster.

    1. Engine Speed Sensor

    The grey wire is situated on the edge of transmission, above the flywheel ring. This sensor sends an electrical signal through the grey wire to pin T55/49. The ECU then uses this information to control fuel, timig and boost. It also sends an indication to the G5 Tachometer in instrument cluster.

    The sensor is used to correlate with the G40 Camshaft position Sensor. The ecu needs to know when the crankshaft is TDC and the location of the camshaft so it can activate spark and injectors in the right way.

    If this sensor fails, the ECU will show an error code P00160 which indicates that the Crank Shaft and Intake Camshaft are not in sync and could indicate the chain stretching or a jump link on the upper timing chain. The code will not appear without the additional information supplied by other sensors (G4 or G40).

    It can be a bit difficult to test as there are several pins on the connector, and they all have different functions. The most effective method to test it is by measuring the resistance between the ECU and the sensor. It should read around 1000 ohms when it is operating at its maximum. If you're having issues with this sensor, look for signs of coolant or oil in the connector bay.

    2. Injectors

    Yesterday, while accelerating at full speed from the highway paytoll, I experienced an abrupt drop in power as if the engine was running out of gas or injectors aren't firing any more. In the morning, i removed the spark plugs, 3 were drenched in gazoline, the fourth one was dry. When I crank the engine with no sparks i put tissue on the top of each hole in the injector and the 3 that were drenched in gazoline jump out but the 4th stays closed. I tried to test the ground connections of ECU pins 14,30 and 48/55. I got 0ohm. I'm assuming the issue is somewhere else.

    I also tried to reset PID but without success. The audi car key replacement cost will start when the G28 is unplugged, and it runs fine with the G28 plugged in. However the intermittent misfire issue continues to occur at higher RPM. The temperature sensor for the coolant (G62) shows the wrong temperature value of that is -49c even after unplugging it. Also, i noticed that the gauge for oil pressure in the cockpit is showing 2 bar while the actual pressure is 0.0 if i crank up the engine.

    I'm not certain what to do, i feel i have pretty much completely ruled out all other possibilities. However, i'm afraid that I might have missed something. Please let me know if you have any ideas! TIA!

    3. Fuel Pump

    The fuel pump in the g28 gets a signal from the RPM sensor. The GM-style sensor is the same as the G4 and both function in the 80, 100, 200, UrS and RS2 cars so you can easily find one at a salvage yard or in a local parts store. It is simple to test them - just switch your DMM into resistance mode and test the distance between pins 1 and 2 (with the bump at the connector's end facing up). They should be infinite Ohms.

    The ECU in our 20vt turbo (3B AAN ABY) engines needs to know both the position and speed of the crankshaft to make decisions regarding timing of the fuel injector, etc. It utilizes a Crank Position Sensor G4 and an Engine Speed Sensor G28 to achieve this. If either of these go badly, you will see codes on the diagnostic scanner which could cause engine shut down.

    A failing G28 sensor could cause an inaccurate gearbox speed counter, a gearbox that shifts more quickly than normal, and/or a misfire in gear. It is likely that your sensor is failing and needs to be replaced if you encounter any of these signs. They are cheap and easy-to-find particularly if they're an Bosch model like ours. Alternately, the GM version of this component is also a good choice.

    5. Tachometer

    A faulty engine speed sensor could be a cause for a slew of problems in your car. It's a crucial component of the transmission of your audi keys because it relays information to the ECU on how fast or slow the engine of the car is spinning. This sensor could cause the transmission to malfunction and other car components to be affected.

    The G5 engine speed sensor is located on the outside of the transmission just above the flywheel ring gear. It transmits a signal to the ECU at pin T55/49, via an uncolored wire. The ECU then processes this signal to regulate fuel, timig and boost and then transmitting it to the G5 tachometer in the instrument cluster. You can check for sensor failure by examining the continuity from the sensor to the tachometer. Also, you can check continuity between pin T55/49 of the ECU and pin T6a/1 of the instrument cluster (trace [79]), and between pin T6a/1 and pin T26a/12. You should observe approximately 1000 ohms resistance between those points. This is the same across the audi Smart key replacement 80-100-200-RS2 series, starting from the 1985 MC all the way up to the 1997 UrS An and 1995 RS2 Du You may also find good ones in wrecking yards.
