Hi Everyone! I'm a newbie to this forum as well to Corsica's. I recently picked up a 1988 Corsica for a commuter that im trying to get to pass smog. Im having trouble with a DTC code 64. My programmer says its a MAP sensor circuit signal voltage low. From what Ive been reading low voltage= low pressure= high vacuum??? Any help to kill this fault code from popping up so i can pass smog would be great! The only symptoms the car is showing is a bit of a low idle and a very small hesitation on initial acceleration.

I found cracked vacuum hoses going to the MAP sensor as well as replaced the sensor with a brand new one. And unfortunately the code keeps popping up after I reset it. Any other suggestions???

Thanks for your help in advance!
Regards
