Audi G28: The Ugly The Truth About Audi G28

Wed, 02 Oct 2024 02:32:56 +0000

How to Replace an Audi G28 Engine Speed Sensor In this video Charles the Humble Mechanic demonstrates how to replace the G28 engine speed sensor. This sensor is located at the top of the transmission just above the flywheel ring gear. It transmits a signal to the ECU via the grey wire (T55/49) and then to the tachometer located in the instrument cluster. 1. Engine Speed Sensor The grey wire is situated on the outside of the transmission, above the flywheel ring. The sensor sends an electrical signal through the grey wire to pin T55/49. The ECU utilizes this information to regulate boost and fuel. It also sends signals to the G5 tachometer inside the instrument cluster. The sensor is used as a reference to correlate 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 start spark and injectors according to the situation. If audi spare key replacement fails to function, the ECU will display an error code P00160. This means that the Crank Shaft is out of sync with the Intake Camshaft. It could also indicate a chain stretch or a jump in the chain link of the upper chain. The code won't appear without the additional information supplied by other sensors (G4 or G40). It is a little tricky to test since there are several pins on the connector and they all have different functions. The best method for doing this is to measure the resistance between the ECU and the sensor. If the sensor is operational, it should read approximately 1000 ohms. If you are having problems with this component, look for signs of oil or coolant in the connector bay. 2. Injectors Yesterday, when accelerating from highway paytoll at a high speed I noticed a massive decrease in power. It was as if the engine had run out of gas. Or my injectors weren't firing. I pulled out the spark plugs this morning, 3 were soaked with gasoline and the fourth was dry. When I crank the engine without sparks, I put a piece of tissue on the top of each of the injector holes, the 3 drenched with gazoline leap out, however the 4th one stays shut. I tried to test the ground connections of ECU pins 14,30 and 48/55. I found zero ohm. Therefore, i think the issue is elsewhere. I also tried to reset the PID without success. The car will start if the G28 is unplugged and is running fine when it is plugged in however it has intermittent misfire issues at higher RPM. The coolant sensor (G62), even when it is unplugged, shows an ice temperature of -49c. I also noticed that the oil gauge in the cockpit shows 2 bars but the actual pressure is 0. I don't know what to do. I believe that I've all other possibilities out. But i am afraid I might have missed something. Let me know If you have any suggestions! TIA! 3. Fuel Pump The fuel pump in the g28 can be activated by a signal sent from the RPM sensor. The GM-style sensor is the same as the G4 and they both work in the 80 100 200, UrS and RS2 cars so you can easily find one at a salvage yard or from a parts store. It is simple to test them to do – just put your DMM in resistance mode and measure between pins 1 (with the bump on the connector's side up) and 2 (2nd from the left on the black end of the connector). audi a4 car key replacement should 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 decisions about fuel injector timing etc. It uses a Crank Position Sensor G4 and an Engine Speed Sensor G28 to accomplish this. If you have a problem with either one of these, the diagnostic scanner will display codes that could lead to an engine shut down. A damaged G28 sensor could cause an inaccurate speed counter for your gearbox, a gearbox that shifts more quickly than normal, or a misfire while in the gear. It is possible that your sensor is failing and needs to be replaced if you experience any of these signs. genuine audi key replacement and easy to locate, especially when they're an Bosch model like ours. Alternately, the GM version of this component is also a good option. 5. Tachometer A damaged engine sensor could cause a variety of issues in your car. It's a vital component of your Audi's transmission, as it sends information to the ECU about how the car's crankshaft is spinning. This sensor can cause the transmission to fail and other components in the car to be affected. The G5 engine speed sensor is located on the outside of the transmission, above the flywheel ring gear. It sends a signal directly to the ECU at pin T55/49, via a grey wire. The ECU then uses and processes the signal to control fuel, timig and boost as well as transmitting it to the G5 tachometer in the instrument cluster. You can check the sensor for failure by checking continuity between it and the tachometer, between the ECU pin T55/49 and the instrument cluster connection on pin T6a/1 (trace [79]) as well as between T6a/1, and the instrument cluster pin T26a/12. You should observe approximately 1000 ohms of resistance between those points. This is a common part that is found across the Audi 80, 100, 200, UrS and RS2 range from 1985 MC until the 1997 UrS AAN and 1995 RS2 ADU, so the best ones might be availble in wrecking yards.
