camshaft position sensor
2000 ford 3.0
I got information from a post to set the sensor by locating the crankshaft to 26 degrees before TDC and taking a voltage reading from dark blue/orange wire to ground. I only read 35 MV max. (should be bat voltage). Can I be 360 degres off on crankshaft.
Any help appeciated.

There are two different systems ford has used... One was a hall-effect type of signal (three pin) and the other was a variable reluctance signal (two pin).
I've never heard of your method being valid, however it may work on a hall-effect setup the "guesstimate" the proper position, but I can guarantee this method will not work with the variable reluctance system.
I have a 2000 B3000 and mine is the variable reluctance system, so I would assume your 2000 ranger would be the same.
Have you had the synchronizer removed or are you trying to diagnose a problem?

I (and I'm sure others) have learned something important today. Good posting.

I have an 04 Ranger 3.0 with a 1336 code. This code means cam and crank are out of sinc. How does the syncronizer work. I do not understand how there could be an out of sinc when the cam and crank are connected by a chain.
I just replaced a cam sensor for a friend who has a 97 3.0 so I have the cam sensor alignment tool.

The pinpoint test for that code can be done with a simple DMM (its the same for DTC P1309):
Diagnostic Trouble Code (DTC) P1309 indicates Misfire Detection Monitor is not enabled.
HD40 CHECK CMP SENSOR OUTPUT — PCM DISCONNECTED
- Disconnect PCM.
- Connect digital multimeter.
- Measure voltage between CMP and PWR GND circuits at the PCM harness connector.
- 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?
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 Electronic Engine Controls, Section 303-14 in the Workshop Manual. If the CMP is installed properly, REPLACE PCM (refer to Section 2, Flash Electrically Erasable Programmable Read Only Memory (EEPROM) ). RESTORE vehicle. COMPLETE Misfire Monitor Repair Verification Drive Cycle
NO - REPLACE CMP sensor. RESTORE vehicle. COMPLETE Misfire Monitor Repair Verification Drive Cycle

- Inspect the Crankshaft Pulse Wheel for damaged teeth.
- Inspect the Crankshaft Pulse Wheel for wobble.
- Inspect for a loose Crankshaft Pulse Wheel.
- Inspect the CKP sensor for damage.
Some other things to consider: Harness routing, alterations, improper shielding, or electrical interference from other improperly functioning systems.
Good luck.

I made a template with paper marking the referenced degree marks in the manual and set accordingly. The truck ran. No codes at this time. Hope It will be ok. This was the
end of replacing head gaskets and exaust valves.
If code would apear, how long from startup?
It runs.

Sorry it has been a long time since I posted. I decided to look into my 1336 code now that I need a smog check soon. I replaced the cam position sensor and crank position sensor. I also re-aligned the cam position sensor with a special tool. Still I am getting the 1336 code. I have an 04 with 134k miles. Crank sensor toothed ring looks good. Could the timing chain have a plastic sprocket on the cam and be loose as hell causing the sensors to go out of sync under engine acceleration and deceleration.
The only other thing I can try is to have the computer reflashed at the dealer, but I hate to spend money at the dealer.
