    I’ve seen this brought up quite a few times but never seen an actual answer. So it happened to me while door deep in the mud. Engine would crank but not fire. Luckily my buddy was able to pull me out with his FJ. After letting the mud dry a bit and we were able to free it from the undercarriage we started looking around and after 45min I noticed a small white with yellow stripe wire that came undone on a connector to some sensor (still trying to figure out what damn sensor it is so I can order the plug). The sensor is on the bottom of the engine on the drivers side above the cross member next to where the exhaust ties into catalytic converter (see pics). I pulled the plug loose and stripped the loose wire back about 1” and poked the bare wire through the connector pin and wrapped it around the pin and plugged the connector back in. Cranked it and she fired right up and no more lights lit up on cluster. So if anyone knows what the correct name is for the sensor so I could order the plug let me know it would be greatly appreciated. 3AE8443E-D4B7-49B8-83FB-3200BDF75300.jpg7D735ABB-3D9C-46EA-A59A-87777CFB0085.jpg4974EA63-F315-43AF-8B8B-FF08B7E407B9.jpg

    Sweet. I just ordered it. The one pic I seen was showing it under the crankshaft pulley in the front of the engine. Just learned there are 5 of them bastards on the engine ‍♂️
