2013年2月19日 · Good Morning everyone, I have a question about a code p0727 I am throwing. Through research on the site I now know that it is engine speed sensor circuit no signal. I have also read that it is a twisted pair wire that goes into a connector over the bell housing. A few months back I discovered...

2016年6月4日 · This is further confirmed by continuing to get P0727 with the brand new engine input speed sensor, and implies a wiring or TCM issue (or something really badly broken in the transmission, based on what Mike L. said, but if that were the case I would think I'd have much more obvious issues, not to mention other codes).

2017年2月18日 · I think the p0700 is getting set by the p0727. If you google the GM DTC P0727 you should be able to find the exact location of the engine speed sensor, two-wire sensor at the top of the bell housing. You didn't say but we are discussing a Duramax aren't we?. I suggest you put your truck details in your signature. Ted

2010年12月27日 · My '01 LB7 is constantly throwing tranny codes of P0700, 0727, 0742. I replaced all 3 transmission sensors (speed, turbine and output) w/OEM sensors. The only time I notice strange tranny behavior is when highway cruising under minimal load around 80mph and sometimes it sounds like the torque...

2012年10月15日 · My handy dandy scantool showed P0726, P0727, and P0846. Truck drove great, but I only got it up to 55mph or so (but the dash was stone dead, so who knows how fast I was really going). Google told me it was likely the transmission pressure switch manifold and/or wiring harness, the fluid was clean, and it shifted great, so despite the codes, I ...

2019年1月13日 · Where do I start? I found this code because the CEL came on for an unrelated issue - MAF sensor issue that was resolve by tightening up the intake connected to the turbo.

2017年9月26日 · P0727 That is the code for the speed sensor on the bell housing. About 10 oclock. Input sensor is reading ( counting ) dimples on the converter.

2011年7月18日 · p0727 I have already replaced the sensors and it seemed to be fine for a while, now she is shift range inhibited on cold starts and slams into Drive or Reverse from nuetral randomly. Getting really aggravated.
