How to Replace an audi key fobs G28 Engine Speed Sensor
In this video Charles the Humble Mechanic demonstrates how to replace the G28 engine speed sensor. The sensor is located 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 located on the instrument cluster.
1. Engine Speed Sensor
The sensor is located at the edge of the transmission just above the flywheel ring gear the G28 Engine Speed Sensor sends a signal to ECU pin T55/49 using a grey wire. The ECU uses this information to regulate the amount of fuel and boost. It also sends an alert to the G5 Tachometer within the instrument cluster.
The sensor is used to link with the G40 Camshaft position Sensor. The ecu must be aware when the crankshaft is TDC and where the camshaft is so it can activate spark and injectors in the right way.
If this sensor fails, the ECU will display the P00160 error, which means the Crank Shaft and Intake Camshaft are out of sync and possibly indicating chain stretch or a jumped link on the upper timing chain. However, the code won't appear on its own, without additional information from other sensors (G4 and G40).
It is a little tricky to test because 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. It should read about 1000 ohms if the sensor is operating at its maximum. Examine for signs of coolant or oil in the connector bay if there are problems with this part.
2. Injectors
Yesterday, while accelerating at full speed from the highway paytoll, i experienced a big cut in power as if the engine was running out of gas or injectors are not firing anymore. I took out the spark plugs this morning, 3 were drenched in gasoline and the fourth was dry. I placed a tissue over each injector hole and when I start the engine with no sparks, the three with gazoline jump out. The fourth one remains closed. I tried to test the ground connections of ECU pins 14,30, and 48/55. I found zero ohm. So i assume the problem is somewhere else.
I also tried to reset PID but without success. The car is able to start when the G28 is disconnected and it runs perfectly when it is plugged in however it is experiencing intermittent misfires at higher RPM. The coolant temperature sensor (G62) shows the wrong temperature value of -49c, even if I unplug it. Also i noticed that the oil pressure gauge in the cockpit is showing 2 bar when the actual pressure is 0.0 if i crank up the engine.
I don't know what to do. I believe that I've eliminated everything else. I'm concerned that i may have missed something. If anyone has any suggestions, please let me know! TIA!
3. Fuel Pump
The fuel pump in the g28 gets a signal 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 locate an extra in a wrecking shop or parts store. It is easy to test them - simply switch your DMM into resistance mode and determine the distance between pins 1 and 2 (with the bump at the connector end facing upwards). They must be infinite Ohms.
4. ECU
The ECU in our 20vt turbo (3B AAN ABY) engines needs to know both the position and speed the crankshaft to determine timing of the fuel injector, etc. To do this, it makes use of a Crank Position Sensor (G4) and an Engine Speed Sensor (G28). If either of these goes wrong, you will receive codes on the diagnostic scanner which could cause engine shut down.
A failing G28 sensor could result in an inaccurate speed counter for your gearbox or a gearbox that shifts faster than normal, and/or an unfire when in the gear. If you have any of these issues, it is most likely that your sensor is going bad and should be replaced. They're cheap and easy to find especially in the case of a Bosch unit like ours. Alternately, GM's version this component is an option.
5. Tachometer
A damaged engine sensor could cause a number of problems in your car. It's a crucial component of the transmission of your Audi Q3 Key (Https://Www.Northwestu.Edu/?URL=Https://Mozillabd.Science/Wiki/5_MustKnow_Hismphash_Practices_You_Need_To_Know_For_2023), as it transmits information to the ECU on how fast or slow the car's engine is spinning. This sensor could cause the transmission to malfunction and other components of the car to be affected.
The G5 engine speed sensor Audi A1 Key Fob (Stormclerk93.Bravejournal.Net) is located at the edge of the transmission just above the flywheel ring gear and sends a signal directly to the ECU at pin T55/49, via an uncolored wire. The ECU then processes the signal to control fuel, timig and boost, and also sends it on to the G5 Tachometer located in the instrument cluster. You can check the sensor for any failure by checking the continuity between it and the tachometer. You can also check continuity between ECU pin T55/49 and the instrument cluster connection via pin T6a/1 (trace [79trace [79]) and between T6a/1 and the instrument cluster pin T26a/12. You should see approximately 1000 ohms resistance between those two pins. This is the same across the audi smart key replacement 80-100-200-RS2 range, from the 1985 MC up to the 1997 UrS AN and 1995 RS2 DU, so you might find some good ones in wrecking yards.
