Code 22 ... Where to start?

If anyone has had to trouble shoot the “Code 22” “Low TBS Voltage Reading” on a 5.7L motor I would like to hear what you’ve found out.

I have a 1995 Suburban with the 5.7L engine. It’s been flashing the code 22 intermittently, over the past few months. I’ve done a visual inspection of the TPS (looks fine), but would like to save some time on trouble shooting the issue.

Any advice is much appreciated.

Thanks,

either the tps is going south or you have a ground issue...check your grounds first
