Also, how easy is this to replace? thanks Re: ECU temp sensor question... [Re: Scotty_Gotti] #721471 05/06/06 07:23 PM Joined: Jan 2000 Posts: 12,153 N. California. USA 4Crawler Web Wheeler Sure. Why? If ECU thinks the engine is cold, it richens up the fuel mix to make the engine warm up faster. r.c.brown@ieee.org TruckEditor@tlca.org Project: 4Crawler 4Crawler OffRoad - 4x4Wire discount code Re: ECU temp sensor question...

In place you'll only have a rough idea of the coolant temps, so you can just get a ballpark guess on whether it is working or not. I recall checking mine when I had the intake off and took it out and cleaned off the side in contact with the coolant. r.c.brown@ieee.org TruckEditor@tlca.org Project: 4Crawler 4Crawler OffRoad - 4x4Wire discount code Re: ECU temp sensor question... [Re: 4Crawler] #721477 05/07/06 03:11 PM Anonymous Unregistered it def. sounds like a problem with that sensor or the egr. would this make it send a code? is that temp sensor the one labeled BVSV? im gunna check these few things. if I can't find the problem will the stealer find the problem for me for a diagnostic fee? and if so can I then just fix it myself without them doing the $$$ labor? i would hate to do this but I just want my new motor to run perfect. sometimes it runs great when warm and sometimes it idles really low and rough cold or warm, but almost always hesitates before gettin on it Re: ECU temp sensor question... #721478 05/07/06 03:25 PM Joined: Jan 2000 Posts: 12,153 N. California. USA 4Crawler Web Wheeler The BVSV is the Bimetal Vacuum Switching Valve that sends vacuum to the EGR modulator once the engine warms up to let is start operating. r.c.brown@ieee.org TruckEditor@tlca.org Project: 4Crawler 4Crawler OffRoad - 4x4Wire discount code Moderated by  4Crawler, 4x4Wire, kewlynx  Hop To Mitsubishi Forums ------  Mitsubishi 4x4 and SUV Tech  Mitsubishi Diesels  Mitsubishi ArchiveToyota Forums ------  Early Toyota Trucks  Toyota 4Runner, FJ Cruiser &...  T100 & Tundra Forum  Tacoma Forum  Toyota Tech ArchiveJeep Forums ------  Jeep Talk  Jeep TechIsuzu Forums ------  Isuzu 4x4 & SUV Talk  Isuzu 4x4 & SUV Tech  Isuzu DieselsKia Forums ------  Kia Talk  Kia Sportage & Sorento TechOff Topic Chat ------  4x4 Gallery  Off-Topic Chat  Recreational Access & Land ...  Politics4xForums ------  Outdoor Gear  General 4x4 Discussion  Tools and Fabrication  General Communications  Amateur Radio  GPS and MapsParts Bin ------  Private Party - Garage Sale  Private Party - Items wanted  Vendors, Hot Deals, Group Buys4x4Wire Back Yard ------  Suzuki Forum  AZ Crawler Crew  Cal-Nev Crew  General Ford 4x4 & SUV Forum  General Dodge 4x4 & SUV Forum  General Chevy 4x4 & SUV ForumFeedback & Testing ------  Problems, Questions, Suggestions4x4Wire Staff ------  Forum Moderators  Problem Threads Print Thread Switch to Threaded Mode 5 Excellent 4 Good 3 Average 2 Bad 1 Terrible View Profile Private Message Follow User Forum Posts View Profile Private Message Homepage Follow User Forum Posts View Profile Private Message Homepage Follow User Forum Posts View Profile Private Message Homepage Follow User Forum Posts View Profile Private Message Homepage Follow User Forum Posts
