i got a P0107 code (if i remember correctly) in my history trouble codes. this P0107 is a map/barometric pressure low. .now my question is wat could this code be from my check engine light is not on cause its only in the history bank. the map sensor is brand new its the one that came with the s/c kit so idk. the only time my c.e.l will come on is when i race it it will flash say 5 times or so and go out the only other code ive had is random misfires which was due to a cracked coil. when i try to check to see what the code is no codes are present only in the history bank which is the map. so im tryin to see what the deal is with that code..and if anyone knows why the c.e.l would flash thats usually just comes up from catalyst damage

CIRCUIT DESCRIPTION
The manifold absolute pressure (MAP) sensor responds to pressure changes in the intake manifold. The pressure changes occur based on the engine load. The MAP sensor has the following circuits:

* 5-volt reference circuit
* Low reference circuit
* MAP sensor signal circuit The powertrain control module (PCM) supplies 5 volts to the MAP sensor on the 5-volt reference circuit. The PCM also provides a ground on the low reference circuit. The MAP sensor provides a signal to the PCM on the MAP sensor signal circuit which is relative to the pressure changes in the manifold. The PCM should detect a low signal voltage at a low MAP, such as during an idle or a deceleration. The PCM should detect a high signal voltage at a high MAP, such as the ignition is ON, with the engine OFF, or at a wide open throttle (WOT). The MAP sensor is also used in order to determine the barometric pressure (BARO). This occurs when the ignition switch is turned ON, with the engine OFF. The BARO reading may also be updated whenever the engine is operated at WOT. The PCM monitors the MAP sensor signal for voltage outside of the normal range.

If the PCM detects a MAP sensor signal voltage that is excessively low, DTC P0107 will set.
