Ground from rear engine block to firewall?

[qslim]

The ground locations are all in section 8W of your manual. If you scroll past the schematics there's a list of all the grounds that correlate to the figures illustrating the locations. I saw @Jerry Bransford post them earlier in another one of your threads.

What codes are you getting? I recently had do.e O2 codes that wouldn't go away. I tested both ends from the sensors to the PCM. Ended up being an electrical gremlin in the harness.

...that’s what I’m guessing it is and instead of continually giving myself a headache trying to figure it out I was just going to remove the whole engine harness and replace it.
Codes after resetting the pcm:

0038 followed by 0058

drive about 10km and I get : 0132 followed by 0152

all 02 sensors are brand new ngk. You’d also have to see my other posts and leading up to these issues. My power steering blew and oil drenched the entire Bay Area. Day after replacing got a camshaft position sensor code followed by 0038 code. Following day after replacing all 02 sensor codes showed up.

been dealing with it since trying to figure it out.

I pulled the plugs to my pcm yesterday and they’re as clean as ever no pins missing no nothing.

wow. That’s a horrible picture. Editing pics on a phone isn’t the best way to do it. Here’s a second attemptView attachment 142459

Ya that’s the g105 ground and then the other one I’m assuming is connected to the back of the engine block which I was asking about earlier today. I need to clean that ground it’s full of oil behind my engine block maybe this is creating a problem
