How to Replace an [https://www.demilked.com/author/johntail87/ audi replacement key] G28 Engine Speed Sensor<br><br>Charles the Humble Technician shows you how to replace the G28 Engine Speed Sensor. This sensor is located near the transmission's edge just above the flywheel gear. It sends a message to the ECU via an uncolored wire T55/49, then to the tachometer located on the instrument cluster.<br><br>1. Engine Speed Sensor<br><br>The grey wire is located on the outside of the transmission, directly above the flywheel ring. The sensor sends signals through the grey wire to pin T55/49. The ECU utilizes this information to regulate boost and fuel. It also sends a signal to the G5 tachometer in the instrument cluster.<br><br>The sensor is used as a reference point 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 trigger spark and injectors in the right way.<br><br>If this sensor fails the ECU will show an error code P00160 which indicates that the Crank Shaft and Intake Camshaft are not in sync, possibly indicating chain stretch or a jumped 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 as there are several pins on the connector and each has its own functions. The best way to do it is to measure the resistance between the ECU and the sensor. It should read approximately 1000 ohms if the sensor is at full operation. Check for signs of coolant, or oil in the connector bay if there are problems with this part.<br><br>2. Injectors<br><br>Yesterday, while accelerating at full speed from the highway paytoll, i experienced a big cut in power like the engine is out of gas or injectors aren't firing anymore. This morning i pull out the spark plugs. Three were drenched in gazoline,  [https://git.openprivacy.ca/rodwinter17 audi tt Key] the fourth one was dry. I put tissue over each hole in the injector and when i start the engine with no sparks, the 3 with gazoline jump right out. The 4th one remains closed. I tried to test the ground connections of ECU pins 14,30 and 48/55. I found 0ohm. I'm assuming that the issue is somewhere else.<br><br>I also tried to reset the PID with no success. The car is able to start if the G28 is disconnected and runs fine when it is plugged in however it has the intermittent misfire issue at higher RPM. The coolant sensor (G62), even when unplugged, still shows an ice temperature of -49c. Also, i noticed that the oil pressure gauge in the cockpit shows 2 bar when the actual pressure is 0.0 if i crank up the engine.<br><br>I'm not sure what to do,  [https://maps.google.nr/url?q=https://blogfreely.net/rabbitglue24/10-reasons-why-people-hate-how-do-i-get-a-replacement-key-for-my-audi-how-do replacement audi key cost uk] as i think i've pretty much completely ruled out all other possibilities. But i'm worried that i might have missed something. If anyone has any suggestions, please let me know! TIA!<br><br>3. Fuel Pump<br><br>The fuel pump of the g28 receives signals from the RPM sensor. The GM-style transmitter is similar to the G4 sender, and both operate on the 80,100,200, UrS, and RS2 vehicles. You can easily find the [https://tagoverflow.stream/story.php?title=15-pinterest-boards-that-are-the-best-of-all-time-about-audi-a4-car-key-replacement audi spare keys] in a salvage shop or parts store. It is easy to test them - just switch your DMM into resistance mode and test the distance between pins 1 and 2 (with the bump at the connector end facing upwards). They should be infinite Ohms.<br><br>4. ECU<br><br>Our 20vt turbo (3B AAN, ABY, and ADU) engines are equipped with an ECU that must know the position and speed of the crankshaft in order to make a decision about fuel injector timing etc. In order to do this it utilizes a Crank Position Sensor (G4) and an Engine Speed Sensor (G28). If you are experiencing issues with either one of these, the diagnostic scanner will display codes that could lead to an engine shutdown.<br><br>The signs of a malfunctioning G28 sensor include an inaccurate rev counter for the gearbox, gears shifting quicker than normal, and/or a misfire when you're in gear. It is possible that the sensor is failing and needs to be replaced if you notice any of these symptoms. They're cheap and easy to find, especially when they're an Bosch unit like ours. You can also choose the GM version of this component is also a good choice.<br><br>5. Tachometer<br><br>A failing engine sensor could cause a variety of issues in your car. It's a vital component of your [https://maps.google.ae/url?q=https://anotepad.com/notes/t37fsaqy audi etron Key]'s transmission, since it relays information to the ECU about how the car's crankshaft is rotating. When this sensor fails, it can cause problems for 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, over the flywheel ring. It sends signals via gray wire to ECU pin T55/49. The ECU utilizes this signal to control the flow of fuel and boost as well as timig. It also sends it to the G5 Tachometer in instrument cluster. You can check for sensor failure by examining the continuity of the sensor to the tachometer. Additionally, you can examine the continuity between pins T55/49 of the ECU and pin T6a/1 of the instrument cluster (trace [79trace [79]) and between pin T6a/1 and pin T26a/12. There should be the resistance to be around 1000 ohms between these two points. This is a typical component across the [https://maps.google.com.lb/url?q=https://mcconnell-jepsen-2.technetbloggers.de/a-look-inside-the-secrets-of-audi-a3-replacement-key audi a3 keys] 80 100 200, UrS and RS2 range from 1985 MC until the 1997 UrS AAN and 1995 RS2 ADU. Good ones could be available in wrecking yards.
