content camshaft position sensors help

adjust engine timing for optimum fuel

O'Reilly Auto Parts Store to determine

which sensor has failed today I'll be

changing the camshaft position sensor on

this 2005 Jeep Liberty with a 3.7 liter

engine this vehicle only has one

camshaft sensor but other vehicles may

have two procedures will vary from one

vehicle to the next so be sure to know

the specifics for your vehicle before

getting started if you're not completely

comfortable doing this yourself we'd be

happy to recommend a professional

technician in your area so if you've

determined this is your problem and

you've got your supplies together here's

what you'll do Park on a level surface

and open the hood for this or anytime

you work with sensors or electrical

components always disconnect your

negative battery cable it may be easiest

to remove and replace the camshaft

sensor from under your vehicle but today

we'll show you how to do it from the top

by removing the air filter housing so

it'll be easier for you to see once

that's out of the way locate the

camshaft position sensor you'll find the

one on this Jeep on the passenger side

of the engine near the front remove the

electrical connector visually inspect

the pigtail to make sure it isn't

damaged or dirty oil and corrosion could

affect the signal from the sensor to the

engine control module remove the bolt on

the camshaft position sensor retaining

ring in our case it's ten millimeters

twist gently to remove the sensor

visually inspect the sensor to make sure

it hasn't been contaminated by a leak

from another engine component if it has

repair the leak to prevent the new

sensor from being damaged check to make

sure the o-ring from the sensor hasn't

fallen into its hole push the new sensor

into place and replace the bolt and

electrical connector tighten the bolt to

manufacturer specifications being

careful not to over tighten the bolt so

you don't damage the mounting ear of the

new sensor replace the air filter

housing by pushing it into the clips in

the inner fender then replace the air

inlet air filter air filter housing
