Test procedure:


Scroll down past the resistance chart.

Could be as simple as the wire/harness falling off the sensor in the driver side head, between #1 and #3 spark plugs.

Just realized, I already responded to your earlier post about the same problem? Any reason you didn’t respond to that post?

Read the first paragraph in the link I gave you. That covers the DVM and resistance measurements. The procedure for measuring volts is covered further down on the that page. The device is probably more accurately described as a “digital multimeter” (DMM).

Read the second sentence of the writeup. It describes a critical requirement for whatever meter you choose - at least 10 megOhms impedance to avoid damaging the PCM. The writeup was prepared 20+ years ago… maybe everything digital meets that specification today.

I have a 25+ year old Craftsman that I bought at Sears, back when they were still selling tools with somewhat decent quality (although no longer made in USA). I'm not up to data on the current choices available. Like anything, the market seems to be dominated by the typical low-priced junk from China. I would ask an electronics professional or hobbiest for a recommendation. I'm a mechanical engineer, not an electrical engineer.

Someone who has a newer make/model that is still available will hopefully fill in the blanks here.
