SES Light

I have been getting an SES light randomly for the last month. Finally I went down to Checker and and borrowed a scanner. Found out I am getting a code 34 which seems to do with the MAP sensor and a code 24 for the vehicle speed sensor.

With this information I would like to know what I should and what solved this issue if you have had it.

Thanks for the help.

You need to check the wiring to be sure voltage and ground are ok. Maybe you have sensor problems. A scan tool would be helpful by letting you watch the readings the pcm is getting.

Some info here might be helpful.
