IGNA14 - Check PCM PIP Signal

^ Key OFF.

^ Disconnect diagnostic cable PIP sensor tee from PIP sensor only; leave PIP sensor tee connected to vehicle harness.

^ Disconnect PCM.

^ Measure the resistance between Pin 34 (PIP) and ground.

^ Is the resistance greater than 10,000 ohms?

YES -- Replace the PCM. Remove all test equipment. Reconnect all components. Clear continuous memory. Rerun quick test.

NO -- Service PIP between PIP sensor and PCM or Ignition Control Module in harness for short. Remove all test equipment. Reconnect all components. Clear continuous memory. Rerun quick test.
