Intake camsensor bank #1 is located at the back of the right valve cover on the left side above the impulse wheel
Exhaust cam sensor bank #1 is located just to the right of the intake cam sensor no the back of the valve cover
Do you now where # 1 cylinder is that bank one (rule of thumb)

Car does not start on my 99 bmw m3 does not turn over either


Many items can cause it not to start:
1. battery voltage too low,
2. fuel pump not working-blown fuse, old, clogged fuel filter,
3. cam shaft sensor fault,
4. crank shaft sensor fault,
5. starter gone, and
6. on BMW M cars, if the oil level is down 3 quarts

Where is fuel trim bank 2 located on bmw 2000 740i bmw


Are you getting the code P0173 That would mean that the ECU was unable to set the correct mixture for cylinders 4-6 (bank 2). I'd guess that the most likely culprit for that failure would be a failing pre-cat O2 sensor based on the code alone.The pre-cat O2 sensors are a critical part of the feedback loop for mixture control. When an O2 sensor ages enough it no longer delivers a valid signal to the ECU, which can cause this fault. The only other component that will affect only bank 2 is the catalytic converter for that bank. Given relative costs of O2 sensors and catalytic converters I'd change out both pre-cat O2 sensors and see if that helps. FYI: O2 sensors are usually staring to fail at 80-90K.

I own a 2002 Jeep Cherokee. Where is the oxygen sensor bank 2 sensor 2 located. This jeep has 4 oxygen sensors. Thanks


the bank 1 and 2 refer to what side of the car ir is on. Bank 1 is passenger side bank 2 is drivers side sensor 1 and 2 refer to before and after the catalytic. sensor 1 is before and 2 is after . i hope this helps and just a references if your cam shaft sensor and crank shaft sensor have not gone bad yet i would have them checked. usually these go bad really quick on jeeps. just had to replace both my cam and crank sensors and with out labor it cost around 100 with labor about 150 to 200. and the o2 sensors run anywhere from about 50 to 150 depends on the quality you want
