ak2018 0 Posted May 25, 2018 I have a Toyota Previa 2005 2.4L Auto (Not import), which has been converted to LPG. The engine light comes up every now and then and the obd-ii error code is P2238. Apparently this type error is typical on a LPG car and I was told to try an o2 sensor extender, so I had an extender fitted and I still get the engine light come on but I think the original code different to what I'm getting now (P2238). I just wanted to know if there is a way to permanently fix this problem with a car thats runs on LPG? Quote Share this post Link to post Share on other sites
