How to Replace an [https://funsilo.date/wiki/Whats_The_Most_Creative_Thing_Happening_With_Replacement_Audi_Key audi spare keys] G28 Engine Speed Sensor<br><br>In this video Charles the humble mechanic demonstrates how to replace the G28 engine speed sensor. The sensor is located near the transmission's edge just above the flywheel gear. It sends a signal to the ECU via a grey wire (T55/49) which is then sent to the tachometer located in the instrument cluster.<br><br>1. Engine Speed Sensor<br><br>The grey wire is situated at the edges of the transmission, above the flywheel ring. This sensor sends a signal via the grey wire to pin T55/49. The ECU utilizes this information to regulate the amount of fuel and boost. It also sends an indicator to the G5 Tachometer within the instrument cluster.<br><br>The sensor is used to link with the G40 Camshaft position Sensor. The ecu must know when the crankshaft is TDC and where the camshaft is located so that it can start spark and injectors according to the situation.<br><br>If this sensor fails when it fails, the ECU will display a P00160 error code. This means that the Crank Shaft is out of alignment with the Intake Camshaft. It could also be a sign of a chain stretch or a jumpy chain link in the upper timing chain. However the code will not appear on its own without additional information from other sensors (G4 and G40).<br><br>It's a bit tricky to test since there are different 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 at full operation. Look for signs of coolant or oil in the connector bay if you have issues with this part.<br><br>2. Injectors<br><br>Yesterday, when i was accelerating to the fullest speed from highway paytoll, i experienced massive power loss like the engine is out of gas or the injectors aren't firing at all. In the morning, i removed the spark plugs, 3 were drenched with gazoline the fourth one was dry. I put a piece of tissue over each hole in the injector and when I turn the engine on without sparks, the ones that have gazoline pop right out. The 4th one stays closed. I checked the ground connection of ECU pins 14,30 and 48/55. I found zero ohm. I'm assuming the issue is in another place.<br><br>I also tried to reset the PID without success. The car will start when the G28 is disconnected, but it runs fine with the G28 plugged in. However, the intermittent misfire problem continues to occur at higher RPM. The temperature sensor for coolant (G62) shows the wrong temperature of -49c even when i unplug it. I also noticed that the gauge for oil pressure in the cockpit shows 2 bar while the actual pressure is 0.0 if i crank up the engine.<br><br>I don't know what to do. I believe that I've ruled everything else out. However, i'm afraid that i might have missed something. Please let me know If you have any suggestions! TIA!<br><br>3. Fuel Pump<br><br>The fuel pump in the g28 receives signals from the RPM sensor. The GM-style sender is identical to the G4 and both function in the 80, 100, 200, UrS and RS2 cars so you can easily find one at a salvage yard or at a parts store. It is simple to test them 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 the left on the black connector's side). They should be infinite Ohms.<br><br>4. ECU<br><br>The ECU of our 20vt turbo (3B AAN ABY) engines requires to know the position and speed of the crankshaft in order to make a decision about timing of the fuel injector, etc. In order to do this it makes use of a Crank Position Sensor (G4) and an Engine Speed Sensor (G28). If you have a problem with either of these, the diagnostic scanner will show the codes that could trigger an engine shutdown.<br><br>A malfunctioning G28 sensor could result in an inaccurate gearbox speed counter, a gearbox that shifts faster than normal, or a misfire while in gear. If you have any of these issues it is most likely that your sensor is failing and requires replacement. The good thing is that they are very cheap and easily accessible, especially if you're looking at the Bosch sensor, like ours. Alternatively, the GM version of this unit is also a good choice.<br><br>5. Tachometer<br><br>A malfunctioning engine speed sensor could be a cause for a slew of issues in your car. It is a crucial part of the [https://images.google.com.na/url?q=https://telegra.ph/12-Stats-About-Audi-Car-Keys-To-Make-You-Take-A-Look-At-Other-People-09-27 audi a4 replacement key]'s transmission since it relays information to the ECU about how fast or slow the vehicle's crankshaft is turning. This sensor can cause the transmission to malfunction and other components in the car to be affected.<br><br>The G5 engine sensor is located near the edge of the transmission, over the flywheel ring. It sends an electrical signal through gray wire to ECU pin T55/49. The ECU then processes the signal to control the flow of fuel, timig and boost and then transmitting it to the G5 Tachometer located in the instrument cluster. You can test for sensor 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 [79]) and between pin T6a/1 as well as pin T26a/12. There should be a resistance of approximately 1000 ohms between these points. This part is common across the [https://www.pinterest.com/angoradesk1/ audi spare key] a5 key fob [[https://www.metooo.es/u/66f75d50f593185a1d10583d click through the next web site]] 80-100-200-RS2 range, from the 1985 MC up to the 1997 UrS AN and 1995 RS2 DU You may also find them in wrecking yards.
