I have a 05 f-250 4x4 5.4 gas automatic trans. and the check engine lite came on, also the abs lite comes on and then goes off. I took to the parts house in town and they scanned it and came up with these codes b1145, b1175, b1236, po500, po191. From reading some of the post, the speed senser also has to do with the abs. The fuel pump module, with the check engine lite. Now I will also tell you the gas guage has not worked in probably a year.nothing new to me as i have always used my trip meter.Any suggestions, thanks
