How to Replace an audi replacement key service near me G28 Engine Speed Sensor
Charles the Humble Technician shows how to replace the G28 Engine Speed Sensor. The sensor is located on the outside of the transmission just above the flywheel gear. It transmits a signal the ECU via an uncolored wire (T55/49), then to the tachometer in the instrument cluster.
1. Engine Speed Sensor
Located on the edge of the transmission just above the flywheel ring gear G28 Engine Speed Sensor sends a signal to ECU pin T55/49 through the grey wire. The ECU utilizes this information to control the amount of fuel and boost. 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 must know when the crankshaft is TDC and where the camshaft is located so that it can trigger spark and injectors in the right way.
If this sensor fails, the ECU will display a P00160 error code. This means that the Crank Shaft is not in alignment with the Intake Camshaft. It could also be a sign of the possibility of a chain stretch or jumpy chain link in the upper timing 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 repairing they all have different functions. The most effective method to test it is by measuring the resistance between the ECU and the sensor. It should read around 1000 ohms if the sensor is in full operation. If you're having issues with this sensor, look for signs of coolant or oil in the connector spare audi key bay.
2. Injectors
Yesterday, while accelerating at full speed from the highway paytoll i had an abrupt drop in power like the engine is out of gas or the injectors are not firing anymore. I took out the spark plugs this morning, 3 were drenched in gasoline and the 4th was dry. When I start the engine without sparks i put tissue on the top of each of the injector holes and Audi Key Programming the 3 that were drenched in gazoline leap out, however the 4th stay shut. I checked the ground connection on ECU pins 14/55, 30/55 and 48/55. I get 0ohm. I assume that the problem is somewhere else.
I also tried to reset the PID without success. The car is able to start if the G28 is not plugged in and it runs perfectly when it is connected but it still has intermittent misfire issues at higher RPM. The coolant temperature sensor (G62) shows the wrong temperature of -49c even when i unplug it. I also noticed that the oil gauge in the cockpit shows 2 bar while the actual pressure is 0.
I'm not sure what to do. I think I've ruled everything else out. But i am afraid I may have missed something. If anyone has any suggestions, please share them! TIA!
3. Fuel Pump
The fuel pump of the g28 gets a signal from 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 so you can easily find one at a wrecking yard or at a parts store. It is easy to test them - just switch your DMM into resistance mode and determine the distance between pins 1 and 2 (with the bump at the connector end facing up). They must be infinite Ohms.
4. ECU
Our 20vt turbo (3B, AAN, ABY and ADU) engines have an ECU that needs to be aware of the speed and position of the crankshaft to make decisions about timing of the fuel injectors, etc. It utilizes a Crank Position Sensor G4 and an Engine Speed Sensor G28 to achieve this. If either of these goes wrong, you will receive codes on the diagnostic scanner which can cause the engine to shut down.
A malfunctioning G28 sensor can cause an inaccurate speed counter for the gearbox, a gearbox that shifts more quickly than normal, and/or a misfire in the gear. It is possible that your sensor is failing and needs to be replaced if you encounter any of these signs. The good news is they are very cheap and easy to find, especially when you're looking at the Bosch unit which is what we have. You can also choose the GM version of this component is also a great option.
5. Tachometer
A failing engine speed sensor could be a cause for a slew of issues in your car. It's an essential component of the transmission in your audi car key replacement cost, as it transmits information to the ECU on how fast or slow the engine is spinning. If the sensor fails, it can cause problems for the transmission as well as the other car's components.
The G5 engine speed sensor is located on the outside of the transmission above the flywheel ring gear and sends a signal to the ECU at pin T55/49 via a grey wire. The ECU is then able to process this signal to regulate fuel, timig, and boost and then sends it on to the G5 tachometer in the instrument cluster. You can check the sensor for failure by examining the continuity between it and the tachometer, between the ECU pin T55/49 and the instrument cluster connection via pin T6a/1 (trace [79]) and between T6a/1 and the instrument cluster pin T26a/12. You should observe around 1000 ohms of resistance between those two pins. This is a standard component across the Audi key replacement Cost 80, 100, 200, UrS and RS2 range from 1985 MC until the 1997 UrS AAN and 1995 RS2 ADU, so the best ones could be available in wrecking yards.
