Can someone please tell me what code 1667 is?

I had some 300 codes cleared at AutoZone after a repair job.

But 1667 then popped up. The guy who cleared the 300 code
could not get rid of the 1667 and suspected it had something
to do with the unit under the dash that involves the code
clearing. If that'* the case, what would a replacement of
that pronged outlet cost? And could 1667 be some other
circuity along the line to the computer?

Thanks, guys!

Happy St. Paddy'* ..... soon

300 codes? Holy cow! Ok, if he cleared that many codes, there'* nothing wrong with your ALDL connector. I don't know what 1667 is. Not in my listing, but it'* not your connector. I don't think there are even 300 OBD2 codes available.

My bet is this guy had his scantool up his ***. No way your PCM was throwing 300 codes unless it'* hosed, or the scantool was. Go get another scan, and in the meantime, someone can chime in on the 1667.

Put your year and model in your signature. It'll help alot!

Oops, sorry to obfuscate the issue! LOL.

Codes 300 thru 306 were cleared after upper intake manifold replaced.

I've got a 98 Bonneville SE

DTC P1667 Reverse Inhibit Solenoid Control Circuit

I THINK that'* the solonoid that prevents you from going into reverse at a certain vehicle speed or RPM. If I'm right, this wouldn't be too serious as long as you were careful shifting.

Anyone wanna back me up here?

I appreciate your efforts!
