So I've got this code which is Manifold Absolute Pressure (MAP) Sensor Signal Lower or higher Than Expected. I've replace the map thinking it would solve the problem. It didn't. Really don't know where to go from here since I don't have a scan tool and idle keeps surging 1 to 2rpm (once reached operating temperature). I am thinking about taking off the iacv and cleaning it out, just to see if it would help the idle. Is it possible for it to be ground or loose wires? All feedback appreciated!

did you reset the ECU after replacing the sensor? there are no other troubleshooting procedures for those codes for a 2003 RSX-S, you have to replace the sensor. if the ECU reset doesn't work, then there's a problem with the plug connector or the wiring.

Yes I've reset the ecu and check light comes on after reaching operating temperature. Wiring seems okay no frays or cuts.
