How did you get the very back engine to trans bolt out. I just can’t find a way to get to it from the top or bottom. Thinks

It seems searching for Journey random horn finds a ton of owners with the same issue but not always the same resolution. Seems like they are all 2010’s with this issue. I’ve got a new clock spring as well as the horn ring on the way. 99% sure it is in the steering wheel as I can stop it by just touching the steering wheel when it happens. Great idea on those rear plugs, I’m sure they are original and have 104K on them. Thanks again! I will post back what I find on the horn. Jeff aka Hemi_JJ

Thanks. It was the knock sensor. I’m not ready to tear the intake off and ended up attaching it to a bracket on the side of the engine. It seems it has to detect it is picking up some engine vibration or it reports a bad knock sensor circuit. No knock, just a bad sensor. now to fix the stupid horn that goes off at random! Dang 2010 Journey issues!

Both the old and new sensors test the same. My thought is that in researching the P0325, it is saying the knock sensor circuit is bad and not that it is detecting a knock. I did a wiring test from end to end including g the connectors and the wiring is good. The new sensor is wrapped in a towel to avoid it detecting any knock and it still triggers as soon as the car hits the 2000 rpm in drive that it has to reach to scan the sensor. I will order a reconditioned controller and see if that resolves it. I will post back in a week.

Also - where is the best place to order a ECU programmed for my car?

So my 2010 Journey (3.5) overheated from a coolant leak and didn’t seem to cause any internal engine damage but now gets an instant P0325 as soon as you reset it and drive it. Engine runs smooth and no knock detected by my ear. I didn’t want to pull the intake to replace the sensor just to discover that was not it, so I bought a new sensor and hooked it up outside the engine. Same issue. I then tracked the 2 wires back to the orange plug on the ECU and they tested fine from pin to pin. I cleaned all the contacts and again, same issue. My gut says bad ECU, but wanted to see if anyone else had any ideas or thoughts on this one. I’m stumped.
