The sensor is situated at the top of the transmission above the flywheel ring gear. It transmits a signal the ECU via an uncolored wire (T55/49), then to the tachometer within the instrument cluster.<br><br>1. Engine Speed Sensor<br><br>It is located on the outside of the transmission above the flywheel ring gear, the G28 Engine Speed Sensor sends an electrical signal to ECU pin T55/49 using an uncolored wire. The ECU then uses this information to control the flow of fuel, timig and boost. It also sends an indication to the G5 Tachometer located in the instrument cluster.<br><br>The sensor is used to connect with the G40 Camshaft position Sensor. The ecu must be aware when the crankshaft is TDC and where the camshaft is located so that it can start spark and injectors accordingly.<br><br>If this sensor fails the ECU will display the P00160 error, which means the Crank Shaft and Intake Camshaft are not in sync, possibly indicating the chain stretching or a jump link on the upper timing chain. The code will not appear without the additional information supplied by other sensors (G4 or G40).<br><br>It can be a bit difficult to test because there are various connector pins, and they all have different functions. The best way to do it is to measure the resistance between the ECU and the sensor. If the sensor is operational, it should be reading approximately 1000 ohms. Examine for evidence of coolant or oil in the connector bay if you are experiencing issues with this component.<br><br>2. Injectors<br><br>Yesterday, while accelerating at full speed from the highway paytoll, i experienced an abrupt drop in power like the engine is running out of gas or injectors aren't firing anymore. This morning i pull out the spark plugs, 3 were soaked with gazoline and the fourth one was dry. When I crank the engine with no sparks i put tissue on the top of each hole in the injector and the 3 drenched with gazoline jump out but the 4th one stays shut. I checked the ground connection on ECU pins 14/55,30/55 and 48/55 I got 0ohm. Therefore, i think the issue is in another place.<br><br>I also tried to reset PID but without success. The car is able to start if the G28 is disconnected and it runs perfectly when it is connected, but still is experiencing intermittent misfires at higher RPM. The coolant sensor (G62), even when it is unplugged, shows a temperature of -49c. Also, i noticed that the gauge for oil pressure in the cockpit shows 2 bar when the actual pressure is 0.0 when i rev the engine.<br><br>I'm not certain what to do, as i feel i have pretty much ruled out everything else. I'm concerned that i may have missed something. If anyone has suggestions, please share them! TIA!<br><br>3. Fuel Pump<br><br>The fuel pump in the g28 receives signals from the RPM sensor. The GM-style transmitter is the same as the G4 and both function in the 80, 100, 200, UrS and RS2 cars so you can easily find one at a wrecking yard or from a parts store. Test them out to do - just put 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 end of the connector). They must be infinite ohms.<br><br>4. ECU<br><br>Our 20vt turbo (3B AAN, ABY and ADU) engines have an ECU that has to be aware of the speed and position of the crankshaft to make a decision about timing of the fuel injector, for example. It makes use of a Crank Position Sensor G4 and an Engine Speed Sensor G28 to accomplish this. If either of these goes badly, you will see codes on the diagnostic scanner that can lead to engine shutdown.<br><br>Some of the signs of a malfunctioning G28 sensor are an inaccurate gearbox rev counter and gears that shift faster than normal and/or misfiring when in gear. If you have any of these issues,  replacement audi Key cost Uk ([https://articlescad.com/in-which-location-to-research-audi-battery-key-replacement-online-281036.html articlescad.com]) it is likely that your sensor is deteriorating and should be replaced. The good news is that they are very cheap and easily accessible particularly when you're looking at a Bosch unit which is what ours are. Alternately, the GM version of this unit is also a good option.<br><br>5. Tachometer<br><br>A failing engine speed sensor could be a cause for numerous problems in your car. It is a crucial part of the [https://finn-hermann-2.hubstack.net/20-audi-battery-key-replacement-websites-taking-the-internet-by-storm-1728046967/ audi a1 car key]'s transmission because it communicates to the ECU about how the car's crankshaft is spinning. If the sensor fails, it will affect the performance of the transmission as well as the other car's components.<br><br>The G5 engine speed sensor is located at the outside of the transmission just above the flywheel ring gear and sends 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 then sends it on to the G5 tachometer in the instrument cluster. You can check the sensor for any failure by checking the continuity between it and the tachometer, between ECU pin T55/49 and the instrument cluster connection on pin T6a/1 (trace [79]) and between pin T6a/1 and the instrument cluster pin T26a/12. You should see the resistance to be around 1000 ohms in these areas. This part is common across the [http://wuyuebanzou.com/home.php?mod=space&uid=1224442 audi lost key] 80-100-200-RS2 series, starting beginning with the 1985 MC and up to the 1997 UrS An and 1995 RS2 Du You may also find good ones in wrecking yards.
