Diagnostic Aids

Check for blocked or pinched vacuum hose to MAP sensor. Check MAP sensor filter for damage, blockage, or water and vapor contamination. Check for engine vacuum leaks. A shifted or incorrectly calibrated MAP sensor may cause DTC P0106 to set. Check for a poor PCM electrical connection.

An intermittent malfunction may be caused by a poor connection, rubbed-through wire insulation, or a wire broken inside insulation. Inspect harness connectors for backed-out terminals, improper mating, broken locks, improperly formed or damaged terminals, or poor terminal-to-wire connections before component replacement.
