P0036 Volkswagen -

Question

Hi. I am getting sensor codes 0030, 0036, and 0042. I also have misfiring on cylinder number 2. Are the oxygen sensor problems secondary to the cylinder misfiring?

Also, I'm getting nowhere trying to solve the misfire problem. I swapped out the ignition coil and replaced the spark plug and I still get misfiring on the same cylinder so it's not the coil or the plug. Ideas?

Hi there,

These codes indicate an issue with the heated O2 sensors on bank 1 sensor 1, 2, and 3. Here is a list of possible causes.
