How to Replace an [https://g28-car-key-solutions90075.blogstival.com/52159387/5-audi-advanced-key-projects-that-work-for-any-budget audi key copy] G28 Engine Speed Sensor<br><br>Charles the Humble Technician shows how to replace the G28 Engine Speed Sensor. This sensor is located at the top of the transmission above the flywheel ring gear. It transmits a signal to the ECU via an uncolored wire (T55/49), then to the tachometer in the instrument cluster.<br><br>1. Engine Speed Sensor<br><br>The grey wire is located at the edges of the transmission, just above the flywheel ring. The sensor transmits signals through the grey wire to pin T55/49. The ECU uses this information to control the amount of fuel and boost. It also sends a signal 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 needs to know when the crankshaft is TDC and where the camshaft is located so that it can trigger spark and injectors in the right way.<br><br>If this sensor fails when it fails, the ECU will display a P00160 error code. This indicates that the Crank Shaft is out of line 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).<br><br>Testing is a bit tricky because there are two pins for the connector and they perform different functions but the most effective method to test it is to measure resistance between the sensor and the ECU. When the sensor is operational, it should be reading approximately 1000 ohms. Check for signs of coolant or oil in the connector bay if you are experiencing issues with this part.<br><br>2. Injectors<br><br>Yesterday, as i was accelerating off the highway paytoll at maximum speed, i noticed a huge drop in power. It was like the engine was running out of gas. Or, my injectors were not firing. I took out the spark plugs this morning, 3 were soaked in gasoline, and the fourth was dry. When I start the engine, there are no sparks, i place a tissue on top of each injector hole and the 3 drenched with gazoline jump out but the 4th stays shut. I tried to test the ground connections of ECU pins 14,30, and 48/55. I got zero ohm. I assume that the problem is somewhere else.<br><br>I also tried to reset the PID with no success. The car will start when the G28 is unplugged, and it is running fine with the G28 connected. However the intermittent misfire issue persists at higher RPM. The coolant temperature sensor (G62) shows the wrong temperature value of that is -49c even after unplugging it. I also noticed that the oil gauge in the cockpit shows 2 bar but the actual pressure is 0.<br><br>I'm not certain what to do, as i feel i have pretty much completely ruled out all other possibilities. But i'm worried that I may have missed something. If anyone has any ideas please share them! TIA!<br><br>3. Fuel Pump<br><br>The fuel pump in the g28 is activated by a signal sent by the RPM sensor. The GM-style sensor is identical to the G4 and both are used in the 80, 100 200, UrS and RS2 cars so you can easily find one at a junkyard or from a parts store. It is simple to test them - put your DMM in resistance mode and measure between pins 1 (with the bump on the connector's end up) and 2 (2nd from left on the black connector's end). They should be infinite Ohms.<br><br>4. ECU<br><br>The ECU in our 20vt turbo (3B AAN ABY ADU) engines requires to know both the position and speed the crankshaft to determine timing of the fuel injector, etc. It utilizes a Crank Position Sensor G4 and an Engine Speed Sensor G28 to achieve this. If either of these goes bad you will get codes on the diagnostic scanner that could cause engine shut down.<br><br>A malfunctioning G28 sensor could result in an inaccurate gearbox speed counter or a gearbox that shifts faster than normal, and/or a misfire in gear. It is likely that the sensor is failing and needs to be replaced if you notice any of these signs. The good news is they are quite affordable and easy to find, especially when you're looking at an Bosch sensor, which is what we have. Alternately, the GM version of this unit is also a good choice.<br><br>5. Tachometer<br><br>A faulty engine speed sensor could be a cause for many problems in your vehicle. It's an essential component of your [https://autolocksmiths73178.blue-blogs.com/36463330/the-next-big-trend-in-the-audi-a3-replacement-key-industry audi replacement key cost uk] car key replacement cost; [https://mnobookmarks.com/story18044360/20-up-and-comers-to-watch-in-the-audi-car-keys-replacement-industry try these out],'s transmission, because it communicates to the ECU about how fast or slow the vehicle's crankshaft is turning. If this sensor fails, it could disrupt the performance of the transmission as well as the rest of the car's components.<br><br>The G5 engine sensor is located near the edge of the transmission, just above the flywheel ring. It sends a signal via gray wire to ECU pin T55/49. The ECU utilizes this signal to control fuel and boost, and also to timigrate. It also transmits it to the G5 Tachometer located in the instrument cluster. You can determine if the sensor is in 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 as well as pin T26a/12. You should see an average resistance of 1000 ohms between these points.
