GStrachan Posted December 1, 2022 Share Posted December 1, 2022 Hi Guys, looking for a a bit of advice on fault code P0237. It’s telling me the turbo boost sensor A circuit is low so assuming the sensor is goosed 🤞🏻 but does anyone know where the hell it actually is?! I also noticed a slight puffing noise coming from one of the injectors which was the injector seal, just waiting for a cutting tool to come as the seat looks a bit pitted so will get that cleaned up before refitting. Anyway, any help on the sensor location would be much appreciated! Quote Link to comment Share on other sites More sharing options...
TomsFocus Posted December 1, 2022 Share Posted December 1, 2022 Which engine size? As you mentioned injector leak I assume it's a 1.6? If so, the boost (MAP) sensor is on the throttle body, top left of the engine as you look at it. It's a 'flat' sensor with one single screw fixing. 1 Quote Link to comment Share on other sites More sharing options...
GStrachan Posted December 1, 2022 Author Share Posted December 1, 2022 Sorry yeah it’s the 1.6, 80KW. Perfect thanks, I was looking at them but trying to find info on the t’internet was near impossible. That’ll be the job tomorrow. At least I managed to get the old injector out today after chiselling off the baked on carbon and squirting some Kroil in, if nobody has heard of this stuff before it’s amazing…. 1 Quote Link to comment Share on other sites More sharing options...
