I have a 2001 bmw 740i code PO452 and po135. Where is the evap ctrl pressure sensor po452 and where is the po135 o2 sensor heater fault (bank1 sensor 1)
P0135 02 sensor heater circuit bank 1 sensor 1
P0452 Evap leak detection pump
The Location for 02 sensor bank 1 sensor is on the passenger side before the catalytic. As for P0452 on BMW you will be dealing with the leak detection pump,for emission,First check the fuel cap, make sure the seal has no cracks,
