How to Replace an audi key replacement near me G28 Engine Speed Sensor
Charles the Humble Technician shows how to replace the G28 Engine Speed Sensor. This sensor is situated near the transmission's edge over the flywheel gear. It transmits a signal to the ECU via an uncolored wire (T55/49), then to the tachometer located in the instrument cluster.
1. Engine Speed Sensor
The grey wire is located on the edge of transmission, just above the flywheel ring. This sensor sends an electrical signal through the grey wire to pin T55/49. The ECU uses this information to control fuel and boost. It also sends an indication to the G5 Tachometer located in the instrument cluster.
The sensor is used to link the G40 Camshaft position Sensor. The ecu must be aware when the crankshaft is TDC and where the camshaft is so it can trigger spark and injectors according to the situation.
If this sensor fails, the ECU will display an error code P00160 which indicates that the Crank Shaft and Intake Camshaft aren't in sync, possibly indicating chain stretch or a jumped link on the upper timing chain. However the code will not appear on its own without additional information from other sensors (G4 and G40).
Testing is a bit tricky since there are two connector pins and they perform different functions but the most effective way to test it is by measuring resistance between the sensor and the ECU. If the sensor is functional, audi A3 replacement key it should read about 1000 ohms. If you're having issues with this sensor, look for evidence of oil or coolant in the connector bay.
2. Injectors
Yesterday, as i was accelerating off the highway paytoll at full speed, i noticed a huge reduction in power. It was like the engine was running out of gas. Or, my injectors weren't firing. In the morning, i removed the spark plugs. Three were drenched with gazoline the fourth was dry. I placed a tissue over each injector hole, and when i turn the engine on without sparks, the 3 that have gazoline pop right out. The fourth one remains closed. I tried to test the ground connections of ECU pins 14,30, and 48/55. I got 0ohm. Therefore, i think the issue is elsewhere.
I also tried to reset the PID without success. The car is able to start if the G28 is not plugged in and it runs perfectly when it is plugged in, but still has intermittent misfire issues at higher RPM. The coolant sensor (G62) even when unplugged, still shows a temperature of -49c. I also noticed that the oil gauge in the cockpit shows 2 bars when the actual pressure is zero.
I'm not sure what to do. I believe that I've ruled everything else out. However, i'm afraid that I may have missed something. Please let me know If you have any suggestions! TIA!
3. Fuel Pump
The fuel pump on the g28 is activated by a signal sent by the RPM sensor. The GM-style transmitter functions similarly to the G4 sender, audi Key replacement and both operate on the 80,100,200, UrS, and RS2 vehicles. It is easy to find the spare in a salvage shop or parts store. Test them out 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 in our 20vt turbo (3B AAN ABY) engines requires to be aware of the position and speed of the crankshaft to make decisions regarding timing of fuel injectors, etc. To accomplish this, it makes use of a Crank Position Sensor (G4) and an Engine Speed Sensor (G28). If either of these sensors go badly, you will see codes on the diagnostic scanner which can cause the engine to shut down.
Some of the symptoms of a malfunctioning G28 sensor include an inaccurate gearbox rev counter, gears shifting quicker than normal and/or a misfire when in gear. If you experience any of these problems, it is likely that your sensor is deteriorating and should be replaced. The good news is they are very affordable and easily accessible particularly when you're looking at the Bosch model, which is what ours are. If you prefer, GM's version of this part would be a good option.
5. Tachometer
A malfunctioning engine sensor can cause a number of problems in your vehicle. It's a crucial component of the transmission in your audi key programming since it sends information to the ECU regarding how fast or slow the engine of the car is turning. This sensor can cause the transmission to malfunction and other car components to be affected.
The G5 engine speed sensor is located on the outside of the transmission, above the flywheel ring gear. It sends a signal directly to the ECU at pin T55/49, via a grey wire. The ECU uses this signal to control fuel and boost, and also timig. It also sends it to the G5 Tachometer in instrument cluster. You can test the sensor for any failure by checking the continuity between it and audi q5 Key the tachometer, between ECU pin T55/49 and the instrument cluster connection via pin T6a/1 (trace [79trace [79]) and between pin T6a/1 and the instrument cluster pin T26a/12. It should show approximately 1000 ohms of resistance between those points. This is a common feature across the Audi A3 key fob Replacement 80-100-200-RS2 range, from the 1985 MC up to the 1997 UrS AN and 1995 RS2 DU You may also find good ones in wrecking yards.
