Code 34
I am getting a code 34 ( map sensor), but I can't find it's location. Some sources say it's on the passenger side high on the firewall. Help please. A photo would be best. Also there seems to be various opinions if the 89 305 tpi has a map sensor or a maf sensor. The parts store lists a map sensor as does my Chilton's manual.
This ones free!

Re: Code 34
You don't have a MAP sensor, you have MAF, forget whther it's high or low signal.
But...don't go looking for a MAP, it's not on that '89
