This is how to read those codes -
- The first digit is B for body, C for chassis, P for powertrain, or U for network.
- The second digit is 0 for SAE or 1 for manufacturer. I have no idea what a “2” is.
- The third digit can be 1 through 8. 1 is for fuel and air metering. I don’t know what a zero in this field means.

Please do it yourself....there are instructions in the DIY thread. Takes about 30 minutes....just be sure to insert the rear of the airfilter into the new maf before snapping down the front.
