How to replace audi key an new audi keys G28 Engine Speed Sensor
In this video, Charles the humble mechanic demonstrates how to replace the G28 engine speed sensor. This sensor is located near the transmission's edge over the flywheel gear. It transmits a signal to the ECU via a grey wire (T55/49) and then to the tachometer located in the instrument cluster.
1. Engine Speed Sensor
The grey wire is situated on the edge of transmission, above the flywheel ring. The sensor transmits signals through the grey wire to pin T55/49. 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 know when the crankshaft is TDC and where the camshaft is so it can trigger spark and injectors accordingly.
If this sensor fails, the ECU will show an error code P00160 which indicates that the Crank Shaft and Intake Camshaft aren't in sync and could indicate 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 as there are various pins on the connector, and they all have different functions. The best method for doing this is by measuring the resistance between the ECU and the sensor. It should read approximately 1000 ohms if the sensor is operating at its maximum. If you're having issues with this part, check for evidence of coolant or oil in the connector bay.
2. Injectors
Yesterday, as i was accelerating off the highway paytoll at maximum speed I noticed a massive decrease in power. It was like the engine was running out of gas. Or, my injectors weren't firing. In the morning, i removed the spark plugs, 3 were drenched in gazoline, the fourth was dry. I put tissue over each injector hole, and when I start the engine without sparks, the ones with gazoline jump right out. The 4th one remains shut. 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 somewhere else.
I also tried to reset PID but without success. The car can start if the G28 is not plugged in and it runs perfectly when it is plugged in, but still has the intermittent misfire issue 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 certain what to do, i think i've pretty much ruled out everything else. I'm afraid i may have missed something. Let me know If you have any suggestions! TIA!
3. Fuel Pump
The fuel pump of the g28 receives signals from the RPM sensor. The GM-style transmitter functions similarly to the G4 sender, and both operate on the 80,100,200, UrS, and cheapest RS2 vehicles. It is easy to find a spare in a wrecking shop or 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 on the connector's edge facing up). They should be infinite Ohms.
4. ECU
Our 20vt turbo (3B, AAN, ABY and ADU) engines have an ECU that must know the position and speed of the crankshaft in order to make a decision about fuel injector timing etc. It utilizes a Crank Position Sensor G4 and an Engine Speed Sensor G28 to achieve this. If either of these sensors go badly, you will see codes on the diagnostic scanner which can cause the engine to shut down.
Some of the symptoms of a failed G28 sensor are an inaccurate rev counter in the gearbox, gears shifting quicker than normal and/or a misfire when in gear. It is probable that the sensor is failing and needs to be replaced if you experience any of these symptoms. They're inexpensive and easy to locate, especially when they're a Bosch model like ours. If you prefer, GM's version of this part would be a good option.
5. Tachometer
A malfunctioning engine sensor can cause a variety of issues in your car. It's a vital component of the audi tt key replacement's transmission as it sends information to the ECU about how the car's crankshaft is spinning. This sensor can cause the transmission to fail and other components in the car to be affected.
The G5 engine sensor is located at the edge of the transmission, just above the flywheel ring. It transmits signals via a gray wire to the ECU pin T55/49. The ECU then uses and processes the signal to control fuel, timig and boost as well as sends it on to the G5 tachometer inside the instrument cluster. You can check the sensor for any failure by checking the continuity between it and the tachometer, between the ECU pin T55/49 and the instrument cluster connection to pin T6a/1 (trace [79]) as well as between T6a/1, and Audi Remote Key (Https://Vuf.Minagricultura.Gov.Co/) the instrument cluster pin T26a/12. You should see a resistance of approximately 1000 ohms between these two points. This part is common across the audi Replacement key service near me 80-100-200-RS2 series, starting from the 1985 MC up to the 1997 UrS AN and 1995 RS2 Du So, you may find some good ones in wrecking yards.
