Checked for Error Codes and this is what I got: P0108 Manifold Absolute Pressure sensor circuit high voltage P0113 Intake Air Temperature (IAT) sensor circuit high voltage P0118 Engine Coolant Temperature (ECT)sensor circuit high voltage P0123 Throttle Position Sensor (TPS) circuit high input. P1498 Exhaust Gas Recirculation (EGR) valve sensor circuit High voltage. P1607 Internal ECU Malfunction. When I erase these codes only three WILL NOT GO AWAY!!!!!(IAT, ECT, & P1607) The rest come as soon as I start the car. It backfires and smokes but run. New Map Sensor and the Code still pops up. How can I fix this? Anybody knows what this means???
