How to Replace an audi key fob replacement cost G28 Engine Speed Sensor
In this video Charles the Humble Mechanic shows 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 signal to the ECU via the grey wire (T55/49) which is then sent to the tachometer located in the instrument cluster.
1. Engine Speed Sensor
The grey wire is located at the edges of the transmission, above the flywheel ring. The sensor transmits a signal via the grey wire to pin T55/49. The ECU then uses this information to control the flow of fuel, timig and boost. It also sends an alert to the G5 Tachometer in instrument cluster.
The sensor Audi Car Keys serves as a reference point to connect with the G40 Camshaft Position Sensor. The ecu must know when the crankshaft reached TDC, and the position of the camshaft, to trigger the spark and injectors.
If this sensor fails when it fails, the ECU will display a P00160 error message. This indicates that the Crank Shaft is not in alignment with the Intake Camshaft. It could also indicate an issue with the chain or a jumpy chain link in the upper timing chain. However, the error code won't appear on its own, without additional information from other sensors (G4 and G40).
Testing is a bit challenging because there are two pins for the connector and they have different functions however the best method of testing it is by measuring resistance between the sensor and the ECU. When the sensor is operational, it should read approximately 1000 ohms. Examine for signs of coolant or oil in the connector bay if you have issues with this component.
2. Injectors
Yesterday, while accelerating from the highway paytoll at a high speed, i noticed a huge drop in power. It was as if the engine was running out of gas. Or, my injectors weren't firing. I pulled out the spark plugs this morning, three were soaked in gasoline, and the fourth was dry. I placed a tissue over each hole in the injector and when I turn the engine on without sparks, Audi Key the 3 that have gazoline pop right out. The 4th one remains closed. I tested 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 disconnected, but it is running fine with the G28 plugged in. However, the intermittent misfire problem still occurs 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 but the actual pressure is zero.
I'm not sure what to do, but i think i've pretty much eliminated everything else. I'm afraid i may have missed something. If anyone has any ideas please let me know! TIA!
3. Fuel Pump
The fuel pump on the g28 is activated by a signal from the RPM sensor. The GM-style sender 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 junkyard or in a local parts store. Test them out 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 left on the black connector's side). They must be infinite Ohms.
4. ECU
The ECU of our 20vt turbo (3B AAN ABY ADU) engines needs to be aware of the position and speed of the crankshaft to make decisions regarding timing of fuel injectors, etc. It utilizes a Crank Position Sensor G4 and an Engine Speed Sensor G28 to accomplish this. If either of these sensors go badly, you will see codes on the diagnostic scanner which can lead to engine shutdown.
Some of the symptoms of a failed G28 sensor are an inaccurate rev counter for the gearbox and gears that shift faster than normal and/or misfiring when you are in gear. It is likely that your sensor is failing and needs to be replaced if you encounter any of these signs. The good thing is that they are very cheap and easily accessible particularly when you're looking at an Bosch unit like ours. If you prefer, GM's version of this part is an option.
5. Tachometer
A malfunctioning engine sensor can cause a variety of issues in your car. It's a vital component of your audi replacement key service near me's transmission, since it relays information to the ECU about how fast or slow the car's crankshaft is spinning. 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 situated on the outside of the transmission just above the flywheel ring gear and transmits a signal to the ECU at pin T55/49 via an uncolored wire. The ECU is then able to process this signal to regulate the flow of fuel, timig and boost, and also transmitting it to the G5 tachometer inside the instrument cluster. You can determine if the sensor is in 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 [79]) and between pin T6a/1 as well as pin T26a/12. You should detect a resistance of approximately 1000 ohms between these points. This part is common across the audi key replacement near me 80-100-200-RS2 range, from the 1985 MC all the way up to the 1997 UrS AN and the 1995 RS2 DU, so you might find some good ones in wrecking yards.
