How to Replace an audi a5 key fob G28 Engine Speed Sensor
Charles the Humble Technician teaches how to replace the G28 Engine Speed Sensor. The sensor is situated near the edges of the transmission, above the flywheel ring gear. It transmits a signal the ECU via the grey wire (T55/49) and then to the tachometer located in the instrument cluster.
1. Engine Speed Sensor
It is located on the outside of the transmission above the flywheel ring gear, the G28 Engine Speed Sensor sends a signal to ECU pin T55/49 using an uncolored wire. The ECU utilizes this information to regulate fuel and boost. It also sends a signal to the G5 tachometer inside the instrument cluster.
The sensor is used to link with the G40 Camshaft position Sensor. The ecu has to know when the crankshaft has reached TDC, and where the camshaft lies to trigger the spark and injectors.
If this sensor fails, the ECU will display an error code P00160. This means that the Crank Shaft is not in alignment with the Intake Camshaft. It could also indicate a chain stretch or a jump in the chain link of the upper chain of timing. However, the code won't appear on its own without additional information from other sensors (G4 and G40).
It can be a bit difficult to test as there are several pins on the connector and each has its own functions. The best method for doing this is by measuring the resistance between the ECU and the sensor. If the sensor is operational, Audi Tt key replacement it should read about 1000 ohms. Look for evidence of coolant or oil in the connector bay if you are experiencing issues with this part.
2. Injectors
Yesterday accelerating full 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. Today, i pulled out the spark plugs. Three were drenched in gazoline, the fourth one was dry. I placed a tissue over each hole in the injector and when i turn the engine on without sparks, the ones with gazoline jump right out. The fourth 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 elsewhere.
I also tried to reset the PID without success. The car will start when the G28 is unplugged, and it is running fine with the G28 connected. However, the intermittent misfire problem continues to occur at higher RPM. The coolant sensor (G62) even when it is unplugged, shows temperatures of -49c. I also noticed that the oil gauge in the cockpit shows 2 bar when the actual pressure is 0.
I'm not sure what to do, i believe that i've ruled out everything else. But i'm worried that I might have missed something. If anyone has any ideas please chime in! TIA!
3. Fuel Pump
The fuel pump in the g28 can be activated by a signal sent by the RPM sensor. The GM-style sensor is the same as the G4 and both function in the 80, 100 200, UrS and RS2 cars which is why you can easily locate one at a junkyard or at a parts store. It is simple to test them by putting your DMM in resistance mode and take measurements between pins 1 (with the bump on the connector's end up) and 2 (2nd from the left on the black connector's side). They must be infinite Ohms.
4. ECU
Our 20vt turbo (3B, AAN, ABY and ADU) engines are equipped with an ECU that has to be aware of the speed and position of the crankshaft to make a decision about timing of the fuel injectors, etc. To accomplish this, it utilizes a Crank Position Sensor (G4) and an Engine Speed Sensor (G28). If either of these goes badly, you will see codes on the diagnostic scanner that can lead to engine shutdown.
A damaged G28 sensor can cause an inaccurate speed counter for the gearbox and a gearbox which shifts faster than normal, or a misfire in the gear. It is possible that the sensor is failing and requires to be replaced if you experience any of these symptoms. They are cheap and easy-to-find especially if they're a Bosch sensor like ours. Alternately, the GM version of this part is also a great option.
5. Tachometer
A malfunctioning engine speed sensor could be a cause for a slew of problems in your vehicle. It's an essential component of the transmission in your Audi since it sends information to the ECU regarding how fast or slowly the engine of the car is turning. When this sensor fails, it could 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 edge of the transmission, above the flywheel ring gear. It sends a signal to the ECU at pin T55/49, via an uncolored wire. The ECU is then able to process the signal to control fuel, timig and boost, and also transmitting it to the G5 tachometer in the instrument cluster. You can check for sensor failure by examining the continuity of 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. There should be the resistance to be around 1000 ohms between these points. This part is common across the audi tt key Replacement 80-100-200-RS2 series, starting from the 1985 MC up to the 1997 UrS AN and 1995 RS2 Du So, you may find good ones in wrecking yards.
