How to Replace an audi lost key G28 Engine Speed Sensor
Charles the Humble Technician teaches you how to replace the G28 Engine Speed Sensor. This sensor is located near the edges of the transmission, above the flywheel ring gear. It sends a message to the ECU via a grey wire T55/49, then to the tachometer on the instrument cluster.
1. Engine Speed Sensor
The sensor is located at the edge of the transmission just above the flywheel ring gear G28 Engine Speed Sensor sends signals to ECU pin T55/49 through an uncolored wire. The ECU utilizes this information to control the amount of fuel and boost. It also sends signals to the G5 tachometer in the instrument cluster.
The sensor serves as a reference to correlate with the G40 Camshaft Position Sensor. The ecu must be aware when the crankshaft is TDC and audi car key replacement the location of the camshaft so it can start spark and injectors accordingly.
If this sensor fails when it fails, the ECU will display a P00160 error message. This indicates that the Crank Shaft is not in sync with the Intake Camshaft. It could also indicate an issue with the chain or a jumpy chain link in the upper chain. However, the error code won't appear on its own without additional information from other sensors (G4 and G40).
Testing can be a bit difficult as there are two different pins for the connector and they have different functions but the most effective method to test it is to measure resistance between the sensor and the ECU. When the sensor is functional, it should read approximately 1000 ohms. Check for evidence of coolant or oil in the connector bay if you are experiencing issues with this component.
2. Injectors
Yesterday, as i was accelerating off the highway paytoll at maximum speed I noticed a significant drop in power. It was like the engine had run out of gas. Or, my injectors were not firing. This morning i pull out the spark plugs. Three were drenched in gazoline, the fourth one was dry. I put a piece of tissue over each injector hole, and when i start the engine without sparks, the three that have gazoline pop right out. The 4th one stays closed. I tested the ground connection of ECU pins 14,30, and 48/55. I got 0ohm. So i assume the problem is in another place.
I also tried to reset the PID without success. The car can start when the G28 is disconnected and it runs perfectly when it is connected however it is experiencing intermittent misfires at higher RPM. The temperature sensor key for audi the coolant (G62) shows the wrong temperature value 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 feel i have pretty much ruled out everything else. But i'm worried that I may have missed something. If anyone has any ideas please share them! TIA!
3. Fuel Pump
The fuel pump in the g28 is activated by a signal from the RPM sensor. The GM-style transmitter is the same as the G4 and both are used in the 80 100 200, UrS and RS2 cars so you can easily find one at a wrecking yard or Audi Car key replacement from a parts store. It is easy to test them - simply put your DMM into resistance mode and determine the distance between pins 1 and 2 (with the bump at the connector's end facing up). They must be infinite Ohms.
4. ECU
The ECU of our 20vt turbo (3B AAN ABY) engines needs to know the speed and position of the crankshaft in order to make a decision about timing of fuel injectors, etc. It makes use of a Crank Position Sensor G4 and an Engine Speed Sensor G28 to achieve this. If you encounter a problem with either of these sensors, the diagnostic scanner will show codes that could lead to the engine shutting down.
Some of the symptoms of a failing G28 sensor include an inaccurate rev counter in the gearbox and gears that shift faster than normal and/or a misfire when in gear. If you are experiencing any of these issues, it is likely your sensor is failing and should be replaced. They are cheap and easy-to-find especially if they're an Bosch model like ours. You can also choose the GM version of this component is also a good choice.
5. Tachometer
A malfunctioning engine sensor can cause a myriad of issues in your car. It's an essential component of the transmission in your Audi Car Key replacement since it sends information to the ECU on how fast or slowly the car's engine is spinning. When this sensor fails, it will affect 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 just above the flywheel ring gear and sends a signal directly to the ECU at pin T55/49 through an uncolored wire. The ECU utilizes this signal to regulate the amount of fuel and boost, and also timig. It also transmits it to the G5 Tachometer located in the instrument cluster. You can test for sensor failure by examining the continuity of the sensor to the tachometer. You can also check continuity between pin T55/49 of the ECU and pin T6a/1 of the instrument cluster (trace [79trace [79]) and between pin T6a/1 and pin T26a/12. You should see approximately 1000 ohms of resistance between these two points. This is the same across the Audi 80-100-200-RS2 series, starting beginning with the 1985 MC and up to the 1997 UrS AN and 1995 RS2 DU So, you may find them in wrecking yards.
