hi i've seen procedures that give a resistance at a temperature as a means of diagnosis, such as this: http://www.st165-all-trac.net/st162manual/fuelinjection/fi100.jpg 1 is there a preferred method for temp reading of parts such as the block, trans, sensors etc? 2 does the temp on the graph mean the temp of the part or ambient air temp? i have no idea how hot a metal sensor would get... 3 anyone got experience with those cheapy point n click infra red temp readers from supa cheap etc? do they give accurate readings? thanks
Never, never, never trust a sensor! Don't know about the cheapie ones but I've used the infrareds in racing etc - excellent Watch carefully and you'll see pit crews using them on brakes, tyres etc all the time. I bought a temp probe ($15) from Dick Smith for my multimeter, works great for me
