How to Replace an Audi G28 Engine Speed Sensor
Charles the Humble Technician shows you how to replace the G28 Engine Speed Sensor. This sensor is situated on the outside of the transmission, above the flywheel gear. It transmits a signal to the ECU through the grey wire T55/49 and then to the tachometer in the instrument cluster.
1. Engine Speed Sensor
The grey wire is situated on the edge of transmission, directly above the flywheel ring. This sensor sends a signal via the grey wire to pin T55/49. The ECU then utilizes this information to regulate the boost, fuel, and timig. It also sends an indicator to the G5 Tachometer within the instrument cluster.
The sensor serves as a reference to correlate with the G40 Camshaft Position Sensor. The ecu must know when the crankshaft is TDC and the location of the camshaft so it can start spark and injectors according to the situation.
If this sensor fails, the ECU will show a P00160 code which means the Crank Shaft and Intake Camshaft are not in sync and could indicate the chain is stretched or a jump link on the upper chain of timing. The code won't appear without the additional information provided by other sensors (G4 or G40).
Testing can be a bit difficult since there are two connector pins, and they perform different functions but the most effective method to test it is to measure the resistance between the sensor and the ECU. If the sensor is operational, it should read about 1000 ohms. If you're having issues with this part, check for signs of coolant or oil in the connector bay.
2. Injectors
Yesterday, when i was accelerating to the fullest speed from highway paytoll i had a big cut in power like the engine is running out of gas or the injectors are not firing anymore. This morning i pull out the spark plugs. Three were soaked with gazoline and the fourth one was dry. When i crank the engine without sparks i put tissue on top of each injector hole, the 3 drenched with gazoline pop out, but the 4th stay closed. I checked the ground connection of ECU pins 14,30, and 48/55. I found 0ohm. I think the issue is in another location.
I also tried to reset the PID with no success. The car can start when the G28 is disconnected and is running fine when it is plugged in however it has the intermittent misfire issue at higher RPM. The coolant sensor (G62), even when it is unplugged, shows a temperature of -49c. I also noticed that the oil gauge in the cockpit shows 2 bars when the actual pressure is 0.
I'm not sure what to do. I think I've eliminated everything else. However, i'm afraid that I might have missed something. If anyone has suggestions, please let me know! TIA!
3. Fuel Pump
The fuel pump in the g28 can be activated by a signal by the RPM sensor. The GM-style sensor 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 wrecking yard or in a local parts store. Testing them is easy by putting your DMM in resistance mode and measure between pins 1 (with the bump on the connector's end up) and 2 (2nd from the left on the black end of the connector). They must be infinite Ohms.
4. ECU
The ECU of our 20vt turbo (3B AAN ABY) engines needs to know both the speed and position of the crankshaft in order to make a decision about fuel injector timing, etc. It makes use of a Crank Position Sensor G4 and an Engine Speed Sensor G28 to accomplish this. If you encounter a problem with either of these, the diagnostic scanner will show the codes that could trigger an engine shut down.
A damaged G28 sensor could result in an inaccurate speed counter for the gearbox or a gearbox that shifts more quickly than normal, or a misfire while in the gear. If you are experiencing any of these issues, it is likely your sensor is going bad and needs replacing. The good news is that they are quite affordable and easy to find, especially if you're looking at the Bosch sensor, which is what ours are. Alternately, GM's version this part would be an option.
5. Tachometer
A faulty engine speed sensor could be the cause of a slew of issues in your car. It's a vital component of your audi a3 keys's transmission, because it communicates to the ECU about how the car key cover audi - http://yerliakor.com/user/waiterlegal5 -'s crankshaft is turning. If the sensor fails, it will disrupt the performance of the transmission, as well as the rest of the car's components.
The G5 engine speed sensor is located at the outside of the transmission, above the flywheel ring gear and sends a signal to the ECU at pin T55/49, via an uncolored wire. The ECU utilizes this signal to control the flow of fuel and boost and also to timigrate. It also relays it to the G5 Tachometer in instrument cluster. You can test for sensor failure by examining the continuity from the sensor to the tachometer. Additionally, you can examine the continuity between pins T55/49 of the ECU and pin T6a/1 of the instrument cluster (trace [79trace [79]) and between pin T6a/1 as well as pin T26a/12. You should observe around 1000 ohms of resistance between those two pins. This is a standard component across the Audi 80 100 200, UrS and RS2 range from 1985 MC to the 1997 UrS AAN and 1995 RS2 ADU. Good ones might be availble in wrecking yards.
