Hi,
That works. The code is related to the manifold absolute pressure sensor (MAP). The amount of intake air flow must be inputted to PCM in order to determine the fuel injection quantity. MAPS calculates the amount of air indirectly by measuring the pressure inside of intake manifold. I suspect either the sensor has failed or there is a wiring/connector issue.
Take a look below and let me know if you are comfortable performing the test. Additionally, check to make sure there is no wiring or connector damage. See pic 2 for the location.
Also, this sensor also functions as an intake air temperature sensor. Either of its functions can cause a hard start.
Let me know if this helps.
Take care,
Joe
