How to Replace an programming audi key G28 Engine Speed Sensor
Charles the Humble Technician teaches how to replace the G28 Engine Speed Sensor. This sensor is located near the edges of the transmission just above the flywheel ring gear. It sends a signal to the ECU via the grey wire (T55/49) and then to the tachometer within the instrument cluster.
1. Engine Speed Sensor
The grey wire is located on the outside of the transmission, above the flywheel ring. This sensor sends signals through the grey wire to pin T55/49. The ECU then utilizes this information to regulate the boost, fuel, and timig. It also sends an indication to the G5 Tachometer in instrument cluster.
The sensor is used to link the G40 Camshaft position Sensor. The ecu has to know when the crankshaft has reached TDC, and the position of the camshaft, so that it can activate the spark and injectors.
If this sensor fails, the ECU will throw a P00160 code which means the Crank Shaft and Intake Camshaft are not in sync and possibly indicating the chain stretching or a jump link on the upper chain of timing. However the code will not appear on its own without additional information from other sensors (G4 and G40).
It's a bit tricky to test because there are different pins on the connector and each has its own functions. The best way to do it is by measuring the resistance between the ECU and the sensor. It should read around 1000 ohms when the sensor is operating at its maximum. Check for evidence of coolant or oil in the connector bay if you are experiencing problems with this part.
2. Injectors
Yesterday, as i was accelerating off the highway paytoll at maximum speed I noticed a massive decrease in power. It was like the engine was running out of gas. Or, my injectors weren't firing. In the morning, i removed the spark plugs, three were soaked with gazoline and the fourth one was dry. When I start the engine, there are no sparks i put tissue on top of each injector hole, the 3 drenched with gazoline jump out but the 4th stay shut. I checked the ground connection of ECU pins 14,30, and 48/55. I found zero ohm. I'm assuming the issue is somewhere else.
I also tried to reset the PID but with no luck. The car will start if the G28 is not plugged in and it runs perfectly when it is plugged in but it still has the intermittent misfire issue at higher RPM. The coolant sensor (G62) even when it is unplugged, shows a temperature of -49c. Also, i noticed that the oil pressure gauge in the cockpit shows 2 bar, whereas the actual pressure is 0.0 when I crank up the engine.
I'm not sure what to do. I think I've eliminated everything else. But i am afraid i might have missed something. If anyone has suggestions, please chime in! TIA!
3. Fuel Pump
The fuel pump in the g28 gets a signal from the RPM sensor. The GM-style sender is the same as the G4 and both are used in the 80 100, 200, UrS and RS2 cars which is why you can easily locate one at a junkyard or in a local parts store. It is simple to test them by putting your DMM in resistance mode and measure the resistance between pins 1 (with the bump on the connector's side up) and 2 (2nd from left on the black connector's end). They must be infinite Ohms.
4. ECU
The ECU in our 20vt turbo (3B AAN ABY) engines requires to be aware of the position and speed the crankshaft to make decisions regarding fuel injector timing, etc. It uses a Crank Position Sensor G4 and an Engine Speed Sensor G28 to accomplish this. If you are experiencing issues with either one of these, the diagnostic scanner will display codes that could cause the engine shutting down.
A damaged G28 sensor can cause an inaccurate speed counter replacement key for audi a4 your gearbox or a gearbox that shifts faster than normal, and/or an unfire when in the gear. If you are experiencing any of these issues, it is likely that your sensor is failing and requires replacement audi Key cost. The good news is that they are quite affordable and readily available particularly if you're looking at an Bosch sensor, like ours. If you prefer, GM's version of this component is a good option.
5. Tachometer
A malfunctioning engine sensor can cause a variety of issues within your vehicle. It's a vital component of your audi a5 key fob's transmission, since it relays information to the ECU about how fast or slow the vehicle's crankshaft is spinning. When this sensor fails, it could disrupt the performance of the transmission and the other car's components.
The G5 engine sensor is located near the edge of the transmission, over the flywheel ring. It transmits an electrical signal through a gray wire to the ECU pin T55/49. The ECU uses this signal to control fuel and boost, and also timig. It also transmits it to the G5 Tachometer in instrument cluster. You can check the sensor for Costs any failure by checking the continuity between it and the tachometer. You can also check continuity between ECU pin T55/49 and the instrument cluster connection via pin T6a/1 (trace [79trace [79]) and between pin T6a/1 and the instrument cluster pin T26a/12. It should show around 1000 ohms of resistance between these two points. This is the same across the audi a4 key replacement 80-100-200-RS2 range, from the 1985 MC all the way up to the 1997 UrS AN and the 1995 RS2 DU You may also find some good ones in wrecking yards.
