My car is reading the map sensor
OBD1 system, you have to clear the ECM after repairs are made.
I disconnected the battery for 12 hours won't that reset everything?
And the car is still running the same also
Yes that normally does it, so now you have to start checking the wiring, sensor grounds are a problem with these cars so start there.
Ok so if it is the ground do I just run one straight from the battery for what should I do?
Dig out your wiring diagram and trace out the ground wire to the point where it is grounded, usually a bolt on the intake somewhere, disconnect the ground and ohm it out to make sure the resistance is normal and not open then make sur the connections are clean when putting it back together. After you checked and repaired if necessary the grounds and you still get the code, then you need to check for computer power to the sensor, that will be about 5 volts, then check the signal return wire from the sensor to the ECM, for open circuit, if all of that checks good then you have a bad new part, it happens.
google your make, model, year, and How to test the map sensor. There is a site that has 3 to 4 pages of info, testing, explanation and what to do after when the light is still there.
Thanks for your vote, rereading, i must mention that no jumper wires or circuits need be added to a system of this type during testing unless directed to do so by the service manual. that can be a mindblower. Enjoy your car, have a great day.
