Cam relearn 2002 Jeep Liberty 3.7

no job stated,
its not spark , 3.7L usa runs 6 COPS, all PCM fired direct
must be playing with what
CAMS
why not say the job, so we can be
ON THE SAME PAGE>?

if not in USA , now be like the time to say,no?
chapter 8 in service manual

posted VAST times,search much?

usa official, book. from jeep,not NET rumors.

no photos. so help will limited .
all cam timing matters.
"not sure what does", the cam, crank, sprocket or pin?
The 2.4L inline 4 engine, is a throw back old Dodge Neons
DOHC engine ,a twin cam head.
2002 is first year, Liberty in USA>
is this the 2.4L turbo engine, EDZ engine.??
KJ jeep it is.
be nice to say what job your working? HOw'd you get here?
if you buy the service manual from jeep
chapter 9s, covers this 2.4 total engine, in one chapter.
but this engine cams are Belt drive. NOT CHAIN.
first post that it really is, this engine? or the VIN, or photos.

so you must be confused on that is there.
the other engine, the 3.7L is a V6 engine vastly different than the 4 banger.
it has chains.
covered in chapter 9- page 71 +
this v6 has a counterbalancer too.
i recommend reading the FSM book on this engine , after counting cylinder, 4 or 6? and reading chapters 9 or 9s.

see KJ 2002 here
RTM read the manual
seen here

No. A crank relearn is sometimes necessary, but that won't keep it from running.

the 2002 has fixed spark timing, so must guess
cam or balancer?
no job stated, so i must guess, why make me guess?
ok lets google search for you

heads off or what?

here it is , read it, then ask questions?

Try replacing the crank sensor and the cam sensor

you cant without proper computer tools

Since a P0340 Could be either the Cam Position Sensor or The Crank Position Sensor they are obviously in 2 different spots, however they both either sit on the back of the engine or on the transmission bellhousing. Your Cam Sensor is at the top and your Crank Sensor is near the bottom.

Hope this gives you some direction. Thanks for using FixYa!
