Live data p0172 p0175
Did t have a scope just a volt meter. Felt it was a good start to clear up the draw first and that if I found a positive grounded out it might be tripping up the pcm and coil voltage. I’ll start over and test on amps with numbers. Battery was not dead.- Jhkj04

Live data p0172 p0175
New BCM and It did work no programing. Still getting a draw, I did find the starter repay or switch wire was crunchy so replaced to the first harness plug under the battery. So still a draw and still seeing odd voltage at the coils when running rich. Also under the still searching category I’m...- Jhkj04

Live data p0172 p0175
I had forgotten that but it was unplugged awhile. I’ll retest and give it 45 min doors shut lights off meter neg term to cable. I’m getting mixed reviews on programming or not on the bcm. I called a couple PCM places and they don’t do BCMs at all which is odd. The 3rd I found wanted 400 for a...- Jhkj04

Live data p0172 p0175
So I’ve been tracking. Before swapping the pcm I found I have a ground out or bad Parasitic draw. Meter between neg post and cable I’m getting voltage on the fuse 3-7-9-15 JB power lines. Tracked 15 to a bad wire behind the radio I believe it’s fixed. Tracked 7-9 to the BCM and it seams it’s...- Jhkj04

BCM Interchangeability
If car computer doesn’t do bcm who does? I think mines bad. Chasing a bad grounding that only goes away when I pull the bcm out.- Jhkj04

Tested each coil plug as it was running one at a time. That’s voltage from the pcm to coil.- Jhkj04

Live data p0172 p0175
It does map I’ll check. Also I just tested the coil voltage while running from the Pc to the plug. Odd numbers all around. Most show 4-8 volts the cleanest white plugs show 0-1-2-3-0-2 a range of low voltage. The only one showing 8-10-12-9 etc was the left front plug and that was first checked...- Jhkj04

Mass air ended up good under heat test just 0 at cold. Pulled the plus and not overly fuel smell at the tail pipe.- Jhkj04

Live data p0172 p0175
Lots of data, I went back and started from point A. If I unplug the mass air meter/air temp shouldn’t something happen? It didn’t react and the new sensor has no resistance. The harness shows volts 3-4-5-6v when running. The sensor is dead.- Jhkj04

Help - how to diagnose a bad catalytic converter?
Having p0172 and 175 - lots done to this point and still not right. New data- cold start coolant temp does read on the scanner at 60 steadily runs up to 79-80-113 seamed normal. Front 02’s randomly ran .100-.324-.845-.730 etc on warm up. Rear 02’s .840 .860 which is similar to what they run...- Jhkj04

Live data p0172 p0175
I did see brittle wire loom up over the transmission from the 02’s but I’m also getting readings on the scan tool of .840-.860-9.40. Did a cold start reading. Coolant 60-70-80-113 went cold to warmed up seamed normal. Both Front 02’s danced .124-.345-.764 as it warmed up and the tears started at...- Jhkj04

Live data p0172 p0175
Fronts changed last week rears in Jan. While driving its allot of neg fuel trim for sure. Also I did injectors and coil packs and plugs. Ngk plugs and 02’s and mopar coils. Rear 02’s had rough wiring could the pcm be bad if they grounded it out? Pics of the driving trim video. Thx for checking...- Jhkj04

Almost got my 04 back on The road after a lift and lots or updated maintenance. Tons of help on this site getting the right lift and in the end pulling the motor to do head gaskets and a TQ. I’ve swapped about ever sensor which all started with the back two 02’s having cut up wires prob shorted...- Jhkj04

Oil on plug. Chasing codes.
I’m lost. New gaskets checked hoses, I’m running out of new parts to add for p0172 175. The factory air filter box wasn’t it. On a positive note while with the light on it did drive 300 miles last weekend for the first time since October only now it’s way cooler.- Jhkj04

Pulled the intake redid the gaskets, reran all the pcv lines added clamps to everything and thought I solved this. Nope, still need to try the stock air box but seams odd it can’t function with a cone filter. P0172 175 are killing me.- Jhkj04
