How to Replace an audi spare key replacement G28 Engine Speed Sensor
Charles the Humble Technician teaches you how to replace the G28 Engine Speed Sensor. The sensor is located near the edges of the transmission above the flywheel ring gear. It sends a signal to the ECU via an uncolored wire (T55/49) and then to the tachometer within the instrument cluster.
1. Engine Speed Sensor
Located on the edge of the transmission, above the flywheel ring gear G28 Engine Speed Sensor sends signals to ECU pin T55/49 through a grey wire. The ECU uses this information to regulate boost and fuel. It also sends an indication 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 of when the crankshaft has reached TDC, and the location of the camshaft in order to activate the spark and injectors.
If this sensor fails when it fails, the ECU will display an error code P00160. This means that the Crank Shaft is out of line with the Intake Camshaft. It could also be a sign of an issue with the chain or a jump in the chain link of the upper chain. The code won't show without the additional information provided by other sensors (G4 or G40).
It can be a bit difficult to test since there are several pins on the connector and each has its own functions. The best way to do it is by measuring the resistance between the ECU and the sensor. When the sensor is fully operational, it should read around 1000 ohms. Look for evidence of coolant or oil in the connector bay if you have problems with this part.
2. Injectors
Yesterday, when accelerating from highway paytoll at a high speed I noticed a massive reduction in power. It was as if the engine had run out of gas. Or, my injectors weren't firing. I took out the spark plugs this morning, three were soaked in gasoline, and the fourth was unclean. I placed a tissue over each injector hole and when i turn the engine on without sparks, the 3 with gazoline jump out. The 4th one stays shut. I checked the ground connection on ECU pins 14/55/30/55/48/55/14/55/48/ I get 0ohm. I'm assuming that the issue is in another location.
I also tried to reset the PID but with no luck. The car can start if the G28 is disconnected and it runs perfectly when it is connected but it still is experiencing intermittent misfires at higher RPM. The temperature sensor for the coolant (G62) shows the wrong temperature value of that is -49c even after unplugging it. Also i noticed that the gauge for oil pressure in the cockpit shows 2 bar when the actual pressure is 0.0 if i crank up the engine.
I'm not certain what to do, i feel i have pretty much eliminated everything else. But i am afraid I might have missed something. Please let me know If you have any suggestions! TIA!
3. Fuel Pump
The fuel pump in the g28 can be activated by a signal by the RPM sensor. The GM-style transmitter functions similarly to the G4 sender, and both operate on the 80,100,200, UrS, and RS2 vehicles. It is easy to find a spare in a wrecking shop or a parts store. It is simple to test them by putting your DMM in resistance mode and take measurements between pins 1 (with the bump on the connector's side up) and 2 (2nd from the left on the black connector's end). They must be infinite Ohms.
4. ECU
The ECU of our 20vt turbo (3B AAN ABY ADU) engines requires to know both the speed and position of the crankshaft to determine timing of fuel injectors, etc. In order to do this it utilizes a Crank Position Sensor (G4) and an Engine Speed Sensor (G28). If either of these go badly, you will see codes on the diagnostic scanner which could cause engine shut down.
A malfunctioning G28 sensor could cause an inaccurate speed counter for your gearbox or a gearbox that shifts faster than normal, or a misfire in the gear. If you are experiencing any of these problems, it is likely that your sensor is deteriorating and requires replacement audi key cost uk. The good news is they are very affordable and readily available, especially if you're looking at the Bosch sensor, like ours. You can also choose the GM version of this unit is also a good choice.
5. Tachometer
A failing engine sensor could cause a number of problems within your vehicle. It is a crucial part of your audi q7 replacement key new audi key blade (https://images.google.com.ly/url?q=https://zenwriting.net/chinhoe82/8-tips-to-enhance-your-replacement-audi-car-key-Game)'s transmission, as it sends information to the ECU about how fast or slow the car's crankshaft is turning. When this sensor fails, it could disrupt the performance of the transmission, as well as the other car's components.
The G5 engine sensor is located at the edge of the transmission, over the flywheel ring. It transmits a signal via a gray wire to the ECU pin T55/49. The ECU utilizes this signal to regulate the amount of fuel and boost, as well as timig. It also relays it to the G5 Tachometer inside the instrument cluster. You can check for sensor failure by examining the continuity from the sensor to the tachometer. You can also 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. There should be an average resistance of 1000 ohms in these areas. This part is common across the audi tt replacement key 80-100-200-RS2 range, beginning with the 1985 MC and up to the 1997 UrS AN and the 1995 RS2 DU So, you may find some good ones in wrecking yards.
