How to Replace an audi a5 key fob G28 Engine Speed Sensor
In this video, Charles the humble mechanic demonstrates how to replace the G28 engine speed sensor. This sensor is situated at the edge of transmission just above the flywheel gear. It transmits a signal to the ECU through a grey 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 G28 Engine Speed Sensor sends signals to ECU pin T55/49 via the grey wire. The ECU uses this information to control fuel and boost. It also sends an indication to the G5 tachometer in the instrument cluster.
The sensor is used to connect with the G40 Camshaft position Sensor. The ecu has to know when the crankshaft reached TDC and also the position of the camshaft, in order to activate the spark and injectors.
If this sensor fails the ECU will show the P00160 error, which means the Crank Shaft and Intake Camshaft are not in sync and possibly indicating the chain stretching or audi Car Keys a jump link on 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).
Testing is a bit tricky as there are two different pins for the connector and they have different functions but the most effective method of testing it is to measure the resistance between the sensor and the ECU. It should read approximately 1000 ohms when the sensor is operating at its maximum. If you are having problems with this component, look for evidence of coolant or oil in the connector bay.
2. Injectors
Yesterday accelerating full speed from highway paytoll i had massive power loss like the engine is out of gas or the injectors are not firing anymore. I pulled out the spark plugs this morning, 3 were soaked in gasoline, and the fourth was dry. When i crank the engine, there are no sparks i put tissue on the top of each of the injector holes, the 3 drenched with gazoline pop out, but the 4th one stays shut. I checked the ground connection of ECU pins 14,30 and 48/55. I found zero ohm. I assume that the problem is in another location.
I also tried to reset PID without success. The car will start when the G28 is disconnected, but it runs fine with the G28 connected. However, the intermittent misfire problem persists at higher RPM. The coolant sensor (G62), even when it is unplugged, shows a temperature of -49c. Also i noticed that the gauge for oil pressure in the cockpit shows 2 bar while the actual pressure is 0.0 if i crank up the engine.
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 any suggestions, please share them! TIA!
3. Fuel Pump
The fuel pump of the g28 receives signals from the RPM sensor. The GM-style transmitter is identical to the G4 sender and works on the 80,100,200, UrS, and RS2 vehicles. You can easily find a spare in a wrecking shop or parts store. It is simple to test them to do - just put your DMM in resistance mode and measure the resistance between pins 1 (with the bump on the connector's end up) and 2 (2nd from the left on the black connector's end). They should be infinite Ohms.
4. ECU
Our 20vt turbo (3B AAN, ABY and ADU) engines have an ECU that has to be aware of the speed and position of the crankshaft to make a decision about timing of the fuel injector, for example. It makes use of a Crank Position Sensor G4 and an Engine Speed Sensor G28 to achieve this. If you are experiencing issues with either of these, the diagnostic scanner will display codes that could lead to an engine shut down.
A damaged G28 sensor could result in an inaccurate gearbox speed counter, a gearbox that shifts faster than normal, or a misfire while in the gear. If you experience any of these problems, it is likely your sensor is failing and requires replacement. They're inexpensive and easy to locate particularly if they're a Bosch model like ours. Alternatively, the GM version of this part is also a good choice.
5. Tachometer
A malfunctioning engine speed sensor could be the reason behind numerous problems in your car. It's a crucial component of the transmission in your audi keys replacement, as it transmits information to the ECU about how fast or slowly the engine is spinning. If this sensor fails, it can cause problems for the transmission and the rest of the car's components.
The G5 engine speed sensor is located at the edge of the transmission, above the flywheel ring gear and transmits a signal to the ECU at pin T55/49, via an uncolored wire. The ECU uses this signal to control the amount of fuel and boost, and also timig. It also transmits it to the G5 Tachometer in instrument cluster. You can check 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 the resistance to be around 1000 ohms between these points. This is a common part across the audi car key holder 80, 100 200, UrS and RS2 range from 1985 MC until the 1997 UrS AAN and 1995 RS2 ADU so good parts could be found in wrecking yards.
