so yeah...lately ive been getting p1309 codes...Also lately in reverse or in low rpms my truck drops rpms and dies sometimes or sounds like its gonna die...Along with the bucking at 1.5krpms.Wtf is up with that?

 

Have you cleaned the MAF?

 

yep cleaned the maf..I will clean it again tomorrow thoe

 

How old are the plugs and wires?

 

brand new pretty much

 

A P1309 is a camshaft position sensor code.

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 .

 

^^^Well there is your answer.

 

haha..It would be easier if it was told to me in plain english and not in mechanical terms.
That damn sensor is waaaaaaaaaaaaaaay back in the block too..What a pain

Connect digital multimeter between PCM test pin 85 and test pins 51 or 103

huh lol? what the heck is pin85,51 or 103?

 

just replace it

 

lol...k...

 

^haha I didnt know what all that ment either...

 

my truck has a similar problem but drops rpm and most of the time dies when i put it in P or N. i don't have a programmer to tell me the code. can someone tell me if its related?

 

is it throwing a code? if so go to like autozone

 

yeah autozone will let you use the obd2 (code reader) if not i have one u can use...It iwll only read it if your check engine light is on...

 

I don't think they can do that anymore at all. Some law or something passed.

 

humm..yeah ok now i recall them turning me down when i asked..I have a scanner if u need to barrow it

 

they still read the codes for people but aren't allowed to clear the CEL

 

I heard that too, but I thought it was only out in California?
