How to Replace an audi q7 replacement key G28 Engine Speed Sensor
In this video, Charles the Humble Mechanic demonstrates how to replace the G28 engine speed sensor. The sensor is located at the top of the transmission, above the flywheel ring gear. It transmits a signal the ECU via an uncolored wire (T55/49) which is then sent to the tachometer located in the instrument cluster.
1. Engine Speed Sensor
The sensor is located at the edge of the transmission, above the flywheel ring gear, the G28 Engine Speed Sensor sends a signal to ECU pin T55/49 via an uncolored wire. The ECU then utilizes this information to regulate the flow of fuel, timig and boost. It also sends signals to the G5 tachometer in the instrument cluster.
The sensor serves as a reference point to connect 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 trigger spark and injectors accordingly.
If this sensor fails, the ECU will throw the P00160 error, which means the Crank Shaft and Intake Camshaft aren't in sync, possibly indicating the chain stretching or a jump link on the upper chain of timing. However, the code won't appear on its own, without additional information from other sensors (G4 and G40).
Testing is a bit tricky because there are two pins for the connector and they serve different purposes but the most effective method of testing it is to measure the resistance between the sensor and the ECU. When the sensor is operational, it should read about 1000 ohms. If you're experiencing issues with this sensor, look for evidence of coolant or oil in the connector bay.
2. Injectors
Yesterday accelerating full speed from highway paytoll, i experienced a big cut in power like the engine is out of gas or injectors are not firing any more. I took out the spark plugs this morning, three were drenched in gasoline and the 4th was dry. I put tissue over each hole in the injector and when I start the engine without sparks, the ones with gazoline jump right out. The 4th one remains closed. I inspected the ground connection on ECU pins 14/55, 30/55 and 48/55. i get zero ohm. So i assume the problem is somewhere else.
I also tried to reset PID but without success. The car will start when the G28 is unplugged, and it is running fine with the G28 plugged in. However the intermittent misfire issue continues to occur at higher RPM. The coolant sensor (G62) even when unplugged, still shows an ice temperature of -49c. I also noticed that the oil gauge in the cockpit shows 2 bar when the actual pressure is zero.
I'm not certain what to do, i think i've pretty much completely ruled out all other possibilities. However, i'm afraid that I might have missed something. If anyone has any suggestions, please let me know! TIA!
3. Fuel Pump
The fuel pump in the g28 is activated by a signal sent by the RPM sensor. The GM-style transmitter functions similarly to the G4 sender, and both operate on the 80,100,200, UrS, and RS2 vehicles. It is easy to find the spare in a salvage shop or a parts store. It is simple to test them - simply put your DMM into resistance mode and measure the distance between pins 1 and 2 (with the bump at the connector's end facing upwards). They must be infinite Ohms.
4. ECU
Our 20vt turbo (3B AAN, ABY and ADU) engines are equipped with an ECU that has to know the position and speed of the crankshaft to make a decision about timing of the fuel injector, for example. In order to do this it uses a Crank Position Sensor (G4) and an Engine Speed Sensor (G28). If either of these go badly, you will see codes on the diagnostic scanner that could cause engine shut down.
Some of the symptoms of a malfunctioning G28 sensor include an inaccurate gearbox rev counter and gears that shift faster than normal and/or misfiring when you're in gear. It is probable that your sensor is failing and requires to be replaced if you encounter any of these signs. They're cheap and easy to find especially in the case of a Bosch unit like ours. You can also choose the GM version of this part is also a good option.
5. Tachometer
A faulty engine speed sensor could be a cause for a slew of issues in your car. It's a vital component of the audi a3 key fob replacement replacement key for audi a3 key for audi fob (describes it)'s transmission because it communicates to the ECU about how the car's crankshaft is spinning. If this sensor fails, it will disrupt the performance of the transmission as well as the rest of the car's components.
The G5 engine sensor is located near the edge of the transmission, over the flywheel ring. It sends a signal via an uncolored wire to the ECU pin T55/49. The ECU then uses and processes the signal to control fuel, timig and boost, and also transmitting it to the G5 tachometer inside the instrument cluster. You can test the sensor for failure by checking continuity between it and the tachometer, between the ECU pin T55/49 and the instrument cluster connection to pin T6a/1 (trace [79trace [79]) as well as between T6a/1, and the instrument cluster pin T26a/12. You should observe approximately 1000 ohms resistance between those two pins. This is a standard component across the audi a5 key fob 80, 100 200, UrS and RS2 range from 1985 MC through the 1997 UrS AAN and 1995 RS2 ADU so good ones might be availble in wrecking yards.
