My Mustang through a P0900 code which is "Clutch Actuator Circuit OPEN". My question is how to I correct this issue.....1. Change clutch switch at pedal ?
2. Or something else ?
I need to fix soon the check engine light is driving me NUTS !!!!!!!!!!!

 

i'm not convinced it's the clutch pedal position
sensor, it seems you would have gotten dtc's
0830 and/or 0833 if it had a problem.

not sure what 0900 really is, it could be
transmission related, but i'm not positive.

 

it could be a bad sensor.
check to see if there are no loose conections and erase the code and if it returns you gotta track it down and go from there

 

Thanks everyone !! I did remove the clutch pedal switch and cleared code after reinstall. Code is still stored, sooooooooooo I'm at the same place I was before. P0900 is as stated and OPEN Circuit somewhere in the clutch actuator system. Any other help guesses would really help. The only reason I won't go to Ford is am supercharged, 04 Cobra block etc, etc.............you know all there going to say is your Mustang is not stock so we can't help.

 

the reason i said i was not convinced is
because that dtc is not listed in the
05/06 service manual.....i did see a
reference to it in a general obdII list
though, while searching for it on the net
yesterday..

if it were me i would check the clutch
pedal position circuit with an ohm meter,
but i understand that you may not be set up
to do that.

if you need the wire colors at the PCM
connector let us know, we can get those
for you.

 

Very helpful information, thanks again. My research shows the only elec. switch for the clutch is located at the pedal area. I'm thinking why not just purchase a new on and plug it in and see what happens. Maybe this switch has gone bad (?) if so that would explain the "OPEN Circuit" issue as addessed in P0900 what do you think?

 

if you have access to an ohm
meter, how about taking the
CPP switch out again and testing
it to be sure.

if the reading on the meter doesn't change,
when you move the plunger in and
out, the switch is definitely bad. if it
does change, that would indicate a possible
wiring issue or that the p0900 code is for something
other than the CPP circuit.

 

I'll do that ASAP, if its not the switch and the code is still P0900 what would you do then? How do you clear a code that isn't the correct problem?

 

first things first, let's see
what the switch test tells us

 

Hammeron....do you remember CrazyAl?...you remind me of him.....so much understanding and info for many aspects of the car....just thought of this while reading the thread.

OP-wish I could help but I am at a loss
