How to Replace an audi key replacement near me G28 Engine Speed Sensor
In this video, Charles the Humble Mechanic shows how to replace the G28 engine speed sensor. This sensor is located on the edge of the transmission just above the flywheel ring gear. It sends a message to the ECU through the grey wire T55/49 and then to the tachometer located on the instrument cluster.
1. Engine Speed Sensor
The grey wire is located at the edges of the transmission, above the flywheel ring. The sensor transmits an electrical signal through the grey wire to pin T55/49. The ECU utilizes this information to regulate the amount of fuel and boost. It also sends an indication to the G5 Tachometer within the instrument cluster.
The sensor is used to correlate with the G40 Camshaft position Sensor. The ecu must know when the crankshaft has reached TDC, and where the camshaft lies in order to activate the spark and injectors.
If this sensor fails to function, the ECU will display a P00160 error message. This means that the Crank Shaft is out of line with the Intake Camshaft. It could also be a sign of a chain stretch or a jumpy chain link in the upper chain of timing. The code won't appear without the additional information provided by other sensors (G4 or G40).
It is a little tricky to test because there are various connector pins, and each one has different functions. The best method for doing this is by measuring the resistance between the ECU and the sensor. If the sensor is functional, it should read about 1000 ohms. Look for signs of coolant or oil in the connector bay if you are experiencing problems with this part.
2. Injectors
Yesterday accelerating full speed from highway paytoll, I experienced massive power loss as if the engine was running 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 start the engine, there are no sparks, I put a piece of tissue on top of each injector hole and the 3 drenched with gazoline leap out, however the 4th stay shut. I checked the ground connection on ECU pins 14/55, 30/55 and 48/55. I got zero Ohm. I'm assuming that the issue is in another location.
I also tried to reset PID but without success. The audi car key replacement will start when the G28 is disconnected, but it runs fine with the G28 plugged in. However, the intermittent misfire problem continues to occur at higher RPM. The coolant sensor (G62), even when it is unplugged, shows temperatures of -49c. Also i noticed that the oil pressure gauge in the cockpit shows 2 bar when 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. But i am afraid i might have missed something. Let me know if you have any ideas! TIA!
3. Fuel Pump
The fuel pump in the g28 receives a signal from the RPM sensor. The GM-style transmitter is similar to the G4 sender and both work on the 80,100,200, UrS, and RS2 vehicles. You can easily find the spare in a salvage shop or a parts store. It is easy to test them - simply put your DMM into resistance mode and test the distance between pins 1 and 2 (with the bump at the connector end facing up). They must be infinite Ohms.
4. ECU
The ECU in our 20vt turbo (3B AAN ABY) engines needs to know both the speed and position of the crankshaft to make decisions regarding timing of fuel injectors, etc. To accomplish this, it makes use of a Crank Position Sensor (G4) and an Engine Speed Sensor (G28). If you have a problem with either one of these, the diagnostic scanner will show the codes that could trigger an engine shutdown.
The signs of a malfunctioning G28 sensor are an inaccurate gearbox rev counter the gears are shifting faster than normal and/or a misfire when you are in gear. It is likely that the sensor is failing and requires to be replaced if you experience any of these signs. The good news is they are quite affordable and easily accessible particularly when you're looking at an Bosch sensor, which is what we have. Alternately, the GM version of this part is also a good option.
5. Tachometer
A failing engine speed sensor could be a cause for a slew of problems in your vehicle. It is a crucial part of your audi car key case audi tt key case Shell (Hl0803.Com)'s transmission, as it sends information to the ECU about how the car's crankshaft is rotating. This sensor can cause the transmission to fail and other components in the car to be affected.
The G5 engine speed sensor is situated on the edge of the transmission above the flywheel ring gear. It sends a signal directly to the ECU at pin T55/49 via an uncolored wire. The ECU then processes this signal to control fuel, timig and boost, and also transmitting it to the G5 tachometer in the instrument cluster. You can test for sensor failure by checking continuity from 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 observe around 1000 ohms of resistance between those points. This is the same across the audi advance key 80-100-200-RS2 series, starting from the 1985 MC all the way up to the 1997 UrS AN and the 1995 RS2 DU, so you might find them in wrecking yards.
