My friends car is throwing two codes right now and Im not sure on how to diagnose this problem....

54 P1336 CSF Sensor Intermittent Interruption

and the other code is a P1399 and I cant find the definition of this code anywhere. I looked on the threads on this site and no luck!!!

 

 

I know there are a lot of techs on here with a lot of knowledge so if anyone can help I would much appreciate it. THANKS

 

TTT

 

Also, is this a common problem.... What would cause this?

 

P1336 Engine Speed (RPM) Fluctuation Sensor Intermittent Interruption

that last code is for chrysler = "wait to start"
You should not be getting that code at all....ever

Check the codes the other way:

Come back with what those codes are

 

but what is that code tryin to tell me? how do i diagnose it?

By doing it the right way.

You shouldn't be getting codes that are impossible for the ECU to emit.

Follow the link pdiggitydogg gave you.

 

What I mean is.... what exactly is this telling me?
P1336 Engine Speed (RPM) Fluctuation Sensor Intermittent Interruption

Is it electrical, mechanical, do I need to replace anything, HOW do I diagnose this problem?

 

It's usually just a bad sensor.

Assuming it's the same as a crankshaft fluctuation sensor...if it's not - then I don't know what it is.

 

54 CKF - crank fluctuation sensor

I did the jump and thats what it says... Could the sensor be bad? could a fuse be bad? could there be something wrong with the wiring? These are the kinds of questions im looking to be answered

 

Where would this sensor be located and do any of you know what the Voltage specs should be for it? I have a DMM so I can test voltage for it... Thanks

 

 

 

you bumped exactly one minute later?

Its located on the oil pump, behind the timing belt, near the crank pulley
Connector is 3 pin and can be seen coming from that area

With ignition OFF:
disconnect ckf and measure the resisntance between pins 1 and 3
Spec ~ 1.6-3.2k

If thats good, then check for individual continuity between both 1 and ground and 3 and ground

Is your friend using an obd1 engine with an obd2 ecu?

 

Thanks I really appreciate the help... Its nice when ppl share their knowledge like this...
