How to Replace an audi q5 key Tt replacement key (yogicentral.Science) G28 Engine Speed Sensor
Charles the Humble Technician shows how to replace the G28 Engine Speed Sensor. This sensor is located near the edges of the transmission above the flywheel ring gear. It transmits a signal to the ECU via the grey wire (T55/49), then to the tachometer in the instrument cluster.
1. Engine Speed Sensor
The sensor is located at the edge of the transmission just above the flywheel ring gear, the G28 Engine Speed Sensor sends an electrical signal to ECU pin T55/49 through an uncolored wire. The ECU uses this information to regulate fuel and boost. It also sends an indicator to the G5 Tachometer located in the instrument cluster.
The sensor serves as a reference for comparing with 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 accordingly.
If this sensor fails to function, the ECU will display a P00160 error code. This means that the Crank Shaft is out of line with the Intake Camshaft. It could also indicate a chain stretch or a jumped chain link in the upper chain of timing. However the code will not appear on its own, without additional information from other sensors (G4 and G40).
Testing is a bit challenging because there are two connector pins, and they serve different purposes but the best method of testing it is to measure the resistance between the sensor and the ECU. If the sensor is operational, audi spare keys (https://bookmarkzones.trade/story.php?title=its-enough-15-things-about-audi-tt-key-were-sick-Of-hearing) it should read about 1000 ohms. If you're having issues with this part, check for evidence of oil or coolant in the connector bay.
2. Injectors
Yesterday accelerating full speed from highway paytoll, I experienced massive power loss like the engine is running out of gas or injectors aren't firing anymore. I took out the spark plugs this morning and found that 3 were soaked in gasoline, and the fourth was dry. When I crank the engine, there are no sparks, I put a piece of tissue on top of each injector hole and the 3 drenched with gazoline jump out but the 4th one stays closed. I tested the ground connection on ECU pins 14/55, 30/55 and 48/55. I get 0ohm. I'm assuming that the issue is elsewhere.
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 connected. However, the intermittent misfire problem still occurs at higher RPM. The coolant sensor (G62) even if it is not plugged in, shows an ice temperature of -49c. I also noticed that the oil gauge in the cockpit shows 2 bars while the actual pressure is zero.
I'm not certain what to do, but i think i've pretty much ruled out everything else. I'm concerned that i may have missed something. Let me know if you have any ideas! TIA!
3. Fuel Pump
The fuel pump of the g28 gets a signal 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 which is why you can easily locate one at a junkyard or from a parts store. It is simple to test them - simply switch your DMM into resistance mode and test the distance between pins 1 and 2 (with the bump at the connector's end facing upwards). They should be infinite ohms.
4. ECU
The ECU in our 20vt turbo (3B AAN ABY) engines requires to know both the position and speed the crankshaft to determine timing of the fuel injector, etc. To do this, it uses a Crank Position Sensor (G4) and an Engine Speed Sensor (G28). If you have a problem with either of these, the diagnostic scanner will display codes that could lead to an engine shutdown.
A failing G28 sensor could result in an inaccurate speed counter for your gearbox, a gearbox that shifts faster than normal, and/or an unfire when in gear. If you have any of these problems, it is most likely that your sensor is going bad and needs replacing. They're cheap and easy to find especially if they're an Bosch model like ours. Alternatively, GM's version of this component is an excellent choice.
5. Tachometer
A damaged engine sensor could cause a number of problems in your vehicle. It is an important part of the transmission in your audi connect key since it sends information to the ECU regarding how fast or slow the engine is spinning. If this sensor fails, it will affect the performance of the transmission, as well as 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 a gray wire to the ECU pin T55/49. The ECU then processes this signal to control fuel, timig and boost and then sends it on to the G5 tachometer in the instrument cluster. You can test the sensor for any failure by checking the continuity between it and the tachometer, between ECU pin T55/49 and the instrument cluster connection to pin T6a/1 (trace [79]) and between T6a/1 and the instrument cluster pin T26a/12. You should see the resistance to be around 1000 ohms between these points. This is a typical part across the audi a3 keys 80 100, 200, UrS and RS2 range from 1985 MC to the 1997 UrS AAN and 1995 RS2 ADU. Good parts could be found in wrecking yards.
