PaulJulien Posted October 1 Report Share Posted October 1 Hi everyone, I have question regarding a no crank issue with my 2010 journey sxt 3.5L In the past I knew my transmission range sensor was going slowly on the fritz. I thought it was that, but following recommendations from the community, I decided to verify my fuses and relays using the electrical diagrams for my 3.5L engine. Going through the many checks, I noticed there was no power going to the pcm relay pin #30. According to the diagram, it was supposed to be hot all the time. I verified the continuity between the positive post on the tipm and pin 30 of the pcm relay, but there was nothing. I verified other relays that are supposed to be hot all the time, and guess what? NO POWER. Could my tipm become defective between the moment I shut-off my car, and came back 45min later or could the wiring diagrams be incorrect? I would like to know how or what can I do,before opening up the tipm. Thanks in advance Quote Link to comment Share on other sites More sharing options...
John/Horace Posted October 1 Report Share Posted October 1 (edited) People have made up a temporary TIPM bypass harness to trouble shoot this type of problem. Because of high cost of the part and tricky trouble shooting. If car has original CPS sensor, crank position sensor; your should pursue this for no start issues. Heat and vibration eventually make them flaky. A fairly cheap plug and play part ($30 -ish) oem original equip manuf being preferred option. Does not always set a code when failing.
