How to Replace an programming audi a3 spare key key - click through the next website page - G28 Engine Speed Sensor
Charles the Humble Technician shows how to replace the G28 Engine Speed Sensor. This sensor is situated near the transmission's edge just above the flywheel gear. It transmits a signal to the ECU through the grey wire T55/49 and then to the tachometer in the instrument cluster.
1. Engine Speed Sensor
The grey wire is situated at the edges of the transmission, above the flywheel ring. This sensor sends a signal via the grey wire to pin T55/49. The ECU utilizes this information to control the amount of fuel and boost. It also sends signals to the G5 Tachometer located in the instrument cluster.
The sensor is used to connect with the G40 Camshaft position Sensor. The ecu must know when the crankshaft reached TDC and also the location of the camshaft so that it can activate the spark and injectors.
If this sensor fails, the ECU will display the P00160 error, which means the Crank Shaft and Intake Camshaft are not in sync, possibly indicating chain stretch or a jumped link on the upper timing chain. The code will not appear without the additional information supplied by other sensors (G4 or G40).
It's a bit tricky to test because there are different connector pins, and each has its own functions. The best way to do it is to measure the resistance between the ECU and the sensor. When the sensor is fully functional, it should read around 1000 ohms. Examine for Programming audi key evidence of coolant or oil in the connector bay if you are experiencing problems with this part.
2. Injectors
Yesterday, while accelerating at full speed from the highway paytoll, i experienced an abrupt drop in power like the engine is out of gas or injectors are not firing any more. I pulled out the spark plugs this morning, 3 were drenched in gasoline and the fourth was unclean. When i crank the engine, there are no sparks i put tissue on the top of each of the injector holes, the 3 drenched with gazoline leap out, however the 4th one stays closed. I tested the ground connection of ECU pins 14,30 and 48/55. I found 0ohm. I'm assuming the issue is in another place.
I also tried to reset PID but without success. The car can start if the G28 is unplugged and it runs perfectly when it is connected, but still has the intermittent misfire issue at higher RPM. The coolant sensor (G62) even when it is unplugged, shows temperatures of -49c. I also 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 sure what to do, but i feel i have pretty much ruled out everything else. I'm worried that i might have missed something. Let me know should you have any suggestions! TIA!
3. Fuel Pump
The fuel pump in the g28 can be activated by a signal by the RPM sensor. The GM-style transmitter is the same as the G4 and both function in the 80, 100 200, UrS and RS2 cars which is why you can easily locate one at a salvage yard or at a parts store. Testing them is easy to do - just put your DMM in resistance mode and measure between pins 1 (with the bump on the connector end up) and 2 (2nd from the left on the black connector's end). They must be infinite Ohms.
4. ECU
Our 20vt turbo (3B, AAN, Programming audi Key ABY and ADU) engines have an ECU that has to know the position and speed of the crankshaft to make decisions about fuel injector timing etc. In order to do this it utilizes a Crank Position Sensor (G4) and an Engine Speed Sensor (G28). If either of these goes bad you will get codes on the diagnostic scanner that could cause engine shut down.
A malfunctioning G28 sensor can cause an inaccurate speed counter for your gearbox, a gearbox that shifts more quickly than normal, or an unfire when in gear. It is probable that your sensor is failing and requires to be replaced if you encounter any of these signs. They are cheap and easy-to-find particularly when they're an Bosch sensor like ours. If you prefer, GM's version of this part would be a good option.
5. Tachometer
A failing engine speed sensor could be the cause of many problems in your vehicle. It is a crucial part of the Audi's transmission because it communicates to the ECU about how fast or slow the car's crankshaft is rotating. If this sensor fails, it can affect the performance of the transmission as well as the rest of the car's components.
The G5 engine speed sensor is located at the edge of the transmission just above the flywheel ring gear and transmits a signal to the ECU at pin T55/49 through an uncolored wire. The ECU utilizes this signal to regulate the amount of fuel and boost, and also timig. It also relays it to the G5 Tachometer in instrument cluster. You can test for sensor failure by examining the continuity of the sensor to the tachometer. Additionally, you can verify continuity between pin T55/49 of the ECU and pin T6a/1 of the instrument cluster (trace [79trace [79]) and between pin T6a/1 and pin T26a/12. You should see an average resistance of 1000 ohms in these areas. This part is common across the audi lost key 80-100-200-RS2 series, starting beginning with the 1985 MC and up to the 1997 UrS AN and the 1995 RS2 Du So, you may find some good ones in wrecking yards.
