Main3s Posted December 22, 2009 Report Share Posted December 22, 2009 A lady I work with is having some issues with her 01 Mazda MPV mini van. Based from the symptoms she described I figured it was a bad o2, which according to the trouble codes is an issue. The one that I don't get is the P1512 – VTCS FAULT (variable tumble control solenoid) what does that control? The other codes are... P0421 – Warm up catalyst below threshold P0171 – System too lean (Bank 1) - this has to do with the O2 sensor P0303 – Cylinder 3 misfire detected The last 3 can all be related if I'm not mistaking, bad plug may cause a poor reading to the o2 and trigger the P0421 code... or vice versa, bad o2. It's the VTCS fault that I'm lost on? I just want to give her some solid advice so if she takes to somewhere she doesn't get screwed over. She knows absolutely nothing about cars and they'd take her to the cleaners if she went in there with nothing. Quote Link to comment Share on other sites More sharing options...
