INNOVA 3123 GM OBD1 Code Reader, Windows XP

Very useful code reader for OBD1 systems. Would recommend

Helped with no check engine light in truck

I dont really need this, but my wife and daughter do. Helps when they're not mechanically inclined. Otherwise use the wire trick to get the codes. Fits in the port under the steering wheel on an S10. Inexpensive, reads codes, works well

I have a 1989 Corvette that was showing a "service engine soon" light. I've got an OBD2 reader, but that's no use on a car of this age. This unit worked exactly as advertised. I plugged it in, and then read the blinking dash light to get the codes. In my case, the accompanying book indicated I had a problem with my mass airflow sensor and/or my manifold absolute sensor. I cleaned the MAF sensor with the correct cleaner and found that my year's engine does not have a MAP sensor. I also replaced the two relays that control the MAF sensor. No more "service engine soon" light!!!! I read negative reviews of this device and how the pins will can come loose and retract into the plastic housing making the device useless. Not sure if they've improved their manufacturing, or I got lucky, but mine is fine. Finally, The internet is full of very good advice on how you can use a paperclip to jump two of the pins on an OBD-1 port and read the blinking code on the dashboard of these older vehicles. I completely agree that this will work and save you the cost of this device. However, the gymnastics (for me) of holding a paperclip precisely in place (with one hand), while turning on the key and reading (and writing down) the blinking light codes up on the center of the dashboard (with the other hand) made this device an easy decision. Maybe if I had a pickup truck or some other large vehicle with plenty of room in the interior to maneuver, I might have gone with the paperclip.

Old school technology…had to lean how to read..reading was acurate..

Get a paper clip or piece of wire and it will be as useful as this scam product. I thought I could bypass the possible burnt out "Service Engine Soon" light in the instrument cluster of my car but this PRC made waste of money has no lights or anything to indicate my Pontiac Fiero engine service codes. 100% ripoff. Fiero owners, please do not buy.

Aggravating having to watch the light blinks. But it works

Works as advertised.

Used it on my 1993 sierra, worked perfect! Would 100% recommend this reader for older trucks

Der Code Reader funktioniert im 1991er Buick Park Avenue!! Sehr hilfreich inkl. Anleitung mit Übersicht der Codes!

Excelente

This worked well on my 1995 car

une étoile parce qu'on peut pas en mettre 0, remplace bêtement un trombone et c'est à peu près tout
