I decided to re-verify my MAF harness voltages. It's getting 12V on the red wire, but the white is reading 5.3 mV (key on/eng off). Specs I've read are 100-500 mV. I am thinking this is not bueno. Where is the other end of that white wire?

On other cars I have replaced conventional rubber vacuum hoses with silicon - the main reason being high heat (around a turbo). That was small I/D stuff, however.

While inspecting the PCV valve on my 1991 Loyale, I cracked the (brittle) hose that connects. Part number seems to be 807415162. Any suggestions for a replacement, or substitute?

Does that harness go all the way inside the passenger compartment?

Been working on other projects and finally got to focus some time on the Loyale. I'm getting code 23 flashing. So would I suspect either 2 bad MAF sensors, or perhaps faulty wiring? So

Thanks! Very helpful.

Hi everyone, Trying to check my vehicle for stored CEL codes. From my recent troubleshooting, the CEL has been illuminated when the car isn't starting properly. Based on my understanding, the wires are in the engine bay, and I need to connect the white connector to read codes. The green connector is a "test" connector. Right so far? When I connect this white connector and turn the key on, all I get is a flashing CEL light. Does that mean there are no stored codes?

It was $50 shipped so I think I'll hang onto it. Apparently a supply of extra parts is a good thing with these cars. I've been a little pressed for time this week, but I plan on checking the codes this weekend.

Well... This one is a used OEM from eBay. Sold as "functional". So I am not sure I proved anything. Either I have two bad ones... or it's not the problem. Leaning toward the latter.

I am aware of the troubleshooting that needs to occur and I do appreciate the suggestions. I had already purchased a (used) MAF and there was certainly no harm in checking to see if it fixed anything. I honestly didn't expect it to.

UPDATE: Replacement MAF did not produce a different result.

I have one on order. The funny thing about the unplugged MAF behavior is that you'd think running in this manner would rule out a fuel pressure issue.

Yes, it restarts every time.

It starts, goes up to around 2K, then dies - all in a matter of seconds. No hunting. you have to feather the throttle to keep it running. I will check the grounds - thanks for that.

It is next on my list. Given the combination of behaviors, I was going for big fish / low hanging fruit first. Thanks for the suggestions.
