4 Trouble Codes
I have a 1997 Mercury Sable LS V6
I have 4 trouble codes I need help with: 1: P1518 - Intake Manifold Runner Control Stuck Open (Bank 1) 2: P0420 - Catalytic Converter System - Efficiency Belwo Threshold (Bank 1) 3: P0171 - System Too Lean (Bank 1) 4: P0174 - System Too lean (Bank 2) Does anyone know how to fix these? Thanks, Trevor |
I have the same 0171 and 0174 codes. Only think I am down to testing now is the fuel pressure (which I don't think is a problem with a new pump), Air Mass Flow sensor. (trying to find the "what it should be for electrical testing). And I am debating if I am going to replace all the H202S sensors on my car (2000 Sable).
Otherwise, runs good. Just annoyed, and am sure it is something simple. I will post my findings. Definately not taking to dealership for 110 diagnostics and not doing anything!!! |
