The temp sensor helps tell the engine how to mix the air and fuel to compensate for air temperature. If this isn't working then the air fuel mix can be off and cause rough idle.
Have the coolant temperature sensor checked, or replace it. (under the intake manifold)....The overdrive will not engage, unless the computer reads that the coolant temp. is at a certain level.
The temperature sensor activate the fan. Unless it was hot wire by a back yard mechanic.
If this is a 6VD1 engine, the camshaft position sensor will be located on the very back of the left bank head (on the inside, under the intake manifold). The easiest way to have it replaced or removed is to take off the intake manifold. The sensor is only secured with one 10mm bolt but it is a frustrating thing to put it back on with the intake installed, unless you have very slim hands.
in the worst dam place in the world under the intake were you cant get to it unless you remove the intake . also if you are going to replace it you need to replace the wire going to it that is more likely the problem than the nox sensor. the wire it thiry five bucks the sensor wholesale is one hondred and fifty good luck
The fan connects to a temperature sensor, unless it's been bypassed. This sensor should be checked first.
There is no such thing as a Cherokee with a 8 cycl unless its a grand Cherokee
Per Suzuki Dealer ...Under the Intake Manifold near back of Engine Block, Unless you have an all wheel drive These are supposed to be internal.
According to the manual the outside temperature sensor is located behind the front bumper. Roughly in the location of the driver side fog lamps would be placed. Unless the car came equipped with an outside temperature gauge getting it to display correctly though the instrument package may be a little iffy.
On the 05 4.2 it is tucked behind the alternator and difficult to see unless you are standing on the driver's side.
# The sensor is located in the exhaust manifold or exhaust pipe and is accessible from under the vehicle # Since the oxygen sensor may be difficult to remove with the engine cold begin by operating the engine until it has warmed to atleast 120 degrees # Disconnect the electrical wire from the oxygen sensor and carefully unscrew the oxygen sensor from the exhaust pipe.Be adviced that excessive force may damage the threads inspect the oxygen sensor for damage unless you are replacing it
Refill the reservoir with coolant and the light should go out unless the switch is broken. Where is the temperature sensor for motor? one for computer
From what I have read : The camshaft position sensor ( mounted on top of the synchronizer ) on the Ford 4.0 L , EFI V6 engine . Is on top of the engine , near the centerline , at the rear of the engine near the firewall ( apparently you can"t see it unless the upper intake manifold is removed )
