Engine Codes - P0101 P0340 P0135

[pofo]

P0101 P0340 P0135. I am getting these code on my S52. They all seam to be linked as the are circuirt error messages. I have checked my ground wires but I am not seeing any issues. Is there something else I can look for?

Computer at work pulls up those codes as being the following:

P0101: Mass airflow sensor
P0135: Oxygen sensor
P0340: Camshaft postion sensor

So I let the car sit for the winter as I dont drive it, but summer is here and I need to get back to figuring this out.

I did know the codes are for circuit range witch has to do with voltage for the most part. I just pulled the ecu hoping water leaked in and corroded the connections, but no luck with that. Going to check harness again maybe I missed something.

Usually those codes indicate that the above listed components have failed and need replaced. The resistors and other electrical components in those sensors deteriorate overtime and that is what causes the circuit range to be off.

If you wanted more information, you could view a live data stream from the OBD if you had such ability. Long story short though, you will likely end up needing a new mass air flow sensor, new camshaft position sensor, and new oxygen sensor(s).

Well they are all new and would be strange if they all failed at the same time, I went threw the motor before I swapped it into my E21. I might have an extra maf I can swap to see if that is the issue but I dont think it is.

Would anyone know if all these sensor are powered by the same circuit?

Oh so its an S52 swapped into an E21 chassis?

Yes its swapped but the wiring is 99% oem, only change is the connection to the fuse box.
