How to Replace an Audi Replacement Key Fob G28 Engine Speed Sensor
Charles the Humble Technician shows you how to replace the G28 Engine Speed Sensor. The sensor is located at the top of the transmission, above the flywheel ring gear. It sends a message to the ECU via an uncolored wire T55/49, then to the tachometer in the instrument cluster.
1. Engine Speed Sensor
Located on the edge of the transmission above the flywheel ring gear, the G28 Engine Speed Sensor sends an electrical signal to ECU pin T55/49 via a grey wire. The ECU then uses this information to control fuel, timig and boost. It also sends an alert to the G5 Tachometer located in the instrument cluster.
The sensor is used as a reference for comparing with the G40 Camshaft Position Sensor. The ecu needs to know when the crankshaft is TDC and where the camshaft is so it can start spark and injectors according to the situation.
If this sensor fails when it fails, the ECU will display a P00160 error code. This indicates that the Crank Shaft is not in alignment with the Intake Camshaft. It could also be a sign of an issue with the chain or a jumpy chain link in the upper chain of timing. However, the error code won't be displayed on its own without additional information from other sensors (G4 and G40).
It is a little tricky to test as there are different pins on the connector, and they all have different functions. The best way to do it is to measure the resistance between the ECU and the sensor. When the sensor is operational, it should read around 1000 ohms. Check for signs of coolant, or oil in the connector bay if you have problems with this part.
2. Injectors
Yesterday, when accelerating from highway paytoll at full speed, i noticed a huge drop in power. It was as if the engine had run out of gas. Or, my injectors were not firing. This morning i pull out the spark plugs, 3 were drenched with gazoline the fourth one was dry. When I crank the engine, there are no sparks i put tissue on the top of each hole in the injector and the 3 that were drenched in gazoline pop out, but the 4th stays shut. I tested the ground connection on ECU pins 14/55,30/55 and 48/55 i get zero ohm. Therefore, i think the issue is in another place.
I also tried to reset the PID but with no luck. The car is able to start if the G28 is not plugged in and it runs perfectly when it is connected but it still has the intermittent misfire issue at higher RPM. The temperature sensor for the coolant (G62) shows the wrong temperature value of -49c even when i unplug it. Also, i noticed that the oil pressure gauge in the cockpit shows 2 bar while the actual pressure is 0.0 when i rev the engine.
I'm not certain what to do, as i think i've pretty much completely ruled out all other possibilities. I'm concerned that i may have missed something. If anyone has any ideas please let me know! TIA!
3. Fuel Pump
The fuel pump on the g28 is activated by a signal by the RPM sensor. The GM-style sender is identical to the G4 and they both work in the 80 100, 200, UrS and RS2 cars which is why you can easily locate one at a salvage yard or in a local parts store. It is easy to test them - simply put your DMM into resistance mode and determine the distance between pins 1 and 2 (with the bump on the connector's edge facing upwards). They should be infinite Ohms.
4. ECU
The ECU of our 20vt turbo (3B AAN ABY ADU) engines must know the position and speed of the crankshaft to make decisions regarding timing of the fuel injector, etc. To accomplish this, it utilizes a Crank Position Sensor (G4) and an Engine Speed Sensor (G28). If you have a problem with either of these, the diagnostic scanner will display codes that could cause an engine shut down.
The signs of a failed G28 sensor are an inaccurate rev counter for the gearbox, gears shifting quicker than normal and/or misfiring when you are in gear. It is probable that your sensor is failing and needs to be replaced if you notice any of these signs. They're inexpensive and easy to locate especially when they're an Bosch model like ours. If you prefer, GM's version of this component is an option.
5. Tachometer
A malfunctioning engine sensor can cause a number of problems in your car. It's a crucial component of the transmission in your replacement audi car key because it relays information to the ECU on how fast or slowly the engine is spinning. If the sensor fails, it could cause problems for the transmission as well as the rest of the car's components.
The G5 engine speed sensor replacement key for audi a4 audi [portal.uaptc.edu] is situated on the edge of the transmission, above the flywheel ring gear. It transmits a signal to the ECU at pin T55/49, via an uncolored wire. The ECU is then able to process this signal to regulate fuel, timig and boost and then sends it on to the G5 tachometer in the instrument cluster. You can test the sensor for failure by checking continuity between it and the tachometer, between ECU pin T55/49 and the instrument cluster connection to pin T6a/1 (trace [79]) and between pin T6a/1 and the instrument cluster pin T26a/12. You should detect a resistance of approximately 1000 ohms between these points. This part is common across the audi replacement key fob 80-100-200-RS2 range, from the 1985 MC all the way up to the 1997 UrS AN and 1995 RS2 Du So, you may find them in wrecking yards.
