P0175

Fix code P0175 System too Rich (Bank 2)

If you have a P0175 System too Rich (Bank 2)trouble code, read this to understand what it means

This trouble code indicates that the oxygen sensor on bank 1 (the bank that does NOT have cylinder #1) is reporting a rich mixture. Do NOT automatically assume that you have a bad oxygen sensor. This code can also be caused by a misfire or a bad fuel pressure regulator.
