Manifold Absolute Pressure (MAP) Sensor The scan tool indicates Diagnostic Trouble Code (DTC) P0106: A range/performance problem (vacuum leak) in the Manifold Absolute Pressure (MAP) Sensor system. The MAP sensor converts manifold absolute pressure into electrical signals and inputs the PCM. SENSOR UNIT — The MIL has been reported on. Problem verification: engine speed at 1,000 rpm for 1 minute with the transmis- sion in Park or neutral. Is DTC P0106 indicated? NO Check the MAP sensor output: 1. Stop the engine. 2. Turn the ignition switch ON (II). 3. Check the manifold absolute pressure with the scan tool. Does it indicate atmospheric YES OUTPUT YES Check for vacuum leakage throttle body. Is there leakage? NO Replace the MAP sensor. Check the MAP sensor output: 1. Stop the engine. 2. Turn the ignition switch ON (II). tool. Replace the MAP sensor.
