Diagnostic Aids

After confirming DTC P0105, use scan tool to access CURRENT DATA to confirm manifold absolute pressure. If MAP sensor value displayed on scan tool is always zero, PIM circuit may be shorted. If MAP sensor value displayed on scan tool is always 130 kPa or more, VC circuit may be open or shorted, or PIM and/or E2 circuit may be open. Using scan tool, read freeze frame data. Freeze frame records engine conditions when malfunction is detected.
