How to Replace an audi tt key programming G28 Engine Speed Sensor
In this video Charles the humble mechanic demonstrates how to replace the G28 engine speed sensor. This sensor is located near the edges of the transmission above the flywheel ring gear. It sends a message to the ECU through the grey wire T55/49 and then to the tachometer located on the instrument cluster.
1. Engine Speed Sensor
It is located on the outside of the transmission just above the flywheel ring gear G28 Engine Speed Sensor sends signals to ECU pin T55/49 using a grey wire. The ECU uses this information to regulate boost and fuel. It also sends a signal to the G5 tachometer inside the instrument cluster.
The sensor is used to link the G40 Camshaft position Sensor. The ecu must know when the crankshaft is TDC and the location of the camshaft so it can activate spark and injectors in the right way.
If this sensor fails, the ECU will display a P00160 error message. This means that the Crank Shaft is out of alignment with the Intake Camshaft. It could also indicate the possibility of a chain stretch or jumped chain link in the upper chain. The code will not appear without the additional information provided by other sensors (G4 or G40).
Testing is a bit tricky because there are two pins for the connector and they serve different purposes but the best method to test it is to measure the resistance between the sensor and the ECU. When the sensor is functional, it should read about 1000 ohms. Look for signs of coolant, or oil in the connector bay if you have issues with this component.
2. Injectors
Yesterday, when accelerating from highway paytoll at full speed I noticed a massive decrease in power. It was as if the engine had run out of gas. Or, my injectors were not firing. Today, i pulled out the spark plugs. Three were soaked with gazoline and the fourth was dry. I put tissue over each hole in the injector and when i start the engine with no sparks, the ones with gazoline jump out. The fourth one remains closed. I checked the ground connection on ECU pins 14/55/30/55/48/55/14/55/48/ I get 0ohm. I think the issue is elsewhere.
I also tried to reset PID without success. The car will start when the G28 is disconnected, but it runs fine with the G28 connected. However, the intermittent misfire problem continues to occur at higher RPM. The temperature sensor for the coolant (G62) shows the wrong temperature value of -49c, even if I unplug it. Also i noticed that the gauge for oil pressure in the cockpit shows 2 bar when the actual pressure is 0.0 when I crank up the engine.
I'm not certain what to do, i think i've pretty much eliminated everything else. I'm worried that i might have missed something. If anyone has suggestions, please chime in! TIA!
3. Fuel Pump
The fuel pump on the g28 is activated by a signal from the RPM sensor. The GM-style transmitter is identical to the G4 sender, and both operate on the 80,100,200, UrS, and RS2 vehicles. It is easy to find the spare in a salvage shop or a parts store. It is simple to test them - just switch your DMM into resistance mode and measure the distance between pins 1 and 2 (with the bump at the connector end facing upwards). They must be infinite ohms.
4. ECU
The ECU of our 20vt turbo (3B AAN ABY) engines must be aware of the position and speed the crankshaft in order to make a decision about fuel injector timing, etc. It utilizes a Crank Position Sensor G4 and an Engine Speed Sensor G28 to achieve this. If you encounter a problem with either one of these, the diagnostic scanner will display codes that could lead to an engine shut down.
A malfunctioning G28 sensor can cause an inaccurate speed counter for the gearbox or a gearbox that shifts faster than normal, and/or a misfire while in the gear. If you have any of these issues it is likely that your sensor is deteriorating and should be replaced. They're inexpensive and easy to locate especially if they're an Bosch model like ours. Alternatively, the GM version of this component is also a great option.
5. Tachometer
A faulty engine speed sensor could be the cause of a slew of problems in your vehicle. It's an essential component of the transmission in your audi car key replacement cost since it sends information to the ECU about how fast or slow the audi car key case's engine is turning. When this sensor fails, it can affect the performance of the transmission and the rest of the car's components.
The G5 engine sensor is located at the outskirts of the transmission, over the flywheel ring. It sends signals via gray wire to ECU pin T55/49. The ECU utilizes this signal to regulate fuel and boost, and also timig. It also relays it to the G5 Tachometer in instrument cluster. You can determine if the sensor is in failure by examining the continuity from the sensor to the tachometer. You can also 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. It should show around 1000 ohms of resistance between these two points. This is a standard component across the audi key shell Tt key replacement audi key fob (www.pcsq28.Com) 80 100, 200, UrS and RS2 range from 1985 MC to the 1997 UrS AAN and 1995 RS2 ADU so good ones might be availble in wrecking yards.
