This is right out of the Ford shop manual........


HD40 CHECK CMP SENSOR OUTPUT

Diagnostic Trouble Code (DTC) P1309 indicates Misfire Detection Monitor is not enabled.

Breakout box installed, PCM disconnected.
Connect digital multimeter between PCM test pin 85 and test pins 51 or 103.
Bump engine in short burst with the starter without starting engine for at least 10 engine revolutions.
Does digital multimeter reading switch between low (less than 2.0 volts DC) and high (greater than 8.0 volts DC)?

Yes
Note: A Hall effect type CMP sensor that is installed out of synchronization will produce a DTC. VERIFY the correct installation by referring to the Powertrain/Engine Group in the Workshop Manual. If the CMP is installed properly, REPLACE PCM. RESTORE vehicle. RERUN Quick Test .

No
REPLACE CMP sensor. RESTORE vehicle. COMPLETE Misfire Monitor Repair Verification Drive Cycle. RERUN Quick Test .
