How could this affect the car

Question

My car runs good but doesn't switch gears or down shift

Answer 1

Hi there

This code is for the atmospheric pressure sensor. This is internal to the ecm on this car. If its not shifting gears this won't be the cause of the problem. You need to check for codes in the transmission control module to try and pinpoint the issue. You may need a scan tool and not just a code reader to resolve this.
