Multiple CEL's. Help!

Yea that crankshaft sensor would be easy to replace just pop the belt off and then maybe like 6 bolts

its just in a crappy area to work tho. shouldnt be to bad since all my skid plates are off and if i get the tire off would be easier

 

[Torspd]

Have to take off the compressor and quite possibly the tensioner pulley bracket. 12mm for the 4 compressor bolts, and 14mm for the 5 or 6 tensioner bracket bolts.

 

[butters607]

Why the tensionor pulley bracket just loosen the tension pop the belt of unbolt the ac compresser and unbolt the sensor

Yea jack it up good get it good and high off the ground I could have that thing out in 20 minutes or less to bad ya werent closer haha

make a quick trip to ft eustis and come fix it for me :eviltongue:

yeah, doesnt look to hard to pull off. i got the alternator offa few times now so this shouldnt be any harder

Don't worry about the crank sensor. CHECK THE CAM TIMING FIRST.

yeah i plan on it. just gotta get everything apart once again when i get time.

 

[wrmathis]

so, pulled the crankshaft position sensor today and damn its a mess behind my a/c compressor. oil just caked all over the place.

anyways, did a resistance check on the crank sensor. the FSM calls for 1850-2450 ohms at 68 degrees. at first i was getting a straight out open. now im gettin about 2100 ohms. and every now and then it will go to open. i think something is wrong with this part. should get the new one in Monday. will try to replace that, clean up everything in the area and see if this fixes the problem. if it is an intermittent issue would explain why i had that one time where it was running fine until i messed around with it again.

if its not the crankshaft sensor, then ill check the timing one more time and see if My68ur8 can swing by and confirm that its good or bad. if thats good, then its going back to stock and going to the dealer. altho it wont go to the dealer until may since ill be going out of town for 2 months

Well, that is weird with the crank sensor. Maybe....... keep us posted.

yeah, what sucks is im not even getting any codes to pop up on the ultragauge while its running like crap and the CEL isnt even on. just idles like crap and just shuts off

 

[wrmathis]

so, a little update. decided to try and pull the APR X-1 again. didnt solve the problem but it did let the engine actually run so i could see if it would throw a code or 2. the codes it threw were

after that, for shits and giggles, i decided to swap the cam sensors. when i did that, i got this:

also, during the "idle" this is what my adv timing is

the engine smells like its running rich since i can just flat out smell fuel after it runs for a little bit.

the next thing im going to check is the actual timing again. gotta figure out what a good day to do this.

The timing looks close to where it's supposed to be change that crank sensor yet?

yep, changed it out. no change. its the first thing i did today. then did all the above

 

[butters607]

Dang man that's not good

 

[wrmathis]

Dang man that's not good

nope its not.

the p0016 and p0018 basically state to fix the timing chain. so thats what im hoping it is after all this.

if its not the timing, i dont know what else it could be :/

 

[butters607]

Yep you may have stretched the timing chain I was searching around

 

[wrmathis]

im guessing if its stretched, ill need to have it replaced huh? no fixing it other wise?

 

[butters607]

Yea there not worth saving. You should be able to tell if it is stretched though does it have a abnormal amount of slack?

 

[Torspd]

There is a timing chain inspection cover on the passenger side of the timing cover. Four bolts hold on the rectangle cover.

It might be that you have a malfunctioning tensioner. Possibly? It is right behind that cover. If your timing chain has any slack in it, then either it is bad, or the tensioner is bad.

To replace the timing chain, isn't too hard, it is just a lengthy process.

 

[1GRracer]

An idea for reference on the inspection cover. If you need, I can upload a whole TIS walk though on the timing chain.
