P0342 Camshaft Position Sensor Circuit Low Input

has anyone ever had this cel OR any experience swapping out the sensors? i'm reluctant to begin my usual throwing parts at it methodology, but this can't be anything major unless i've chipped a timing chain tooth/ and i think i would have determined something that catastrophic by now. car runs perfect ( so far!? ) no rough idle/starting nothing odd like stalls etc.

apparently this cel can be caused by a bad starter, low battery, loose ground strap, or wires to alt? but generally speaking ( from what I've read ) all roads lead back to faulty cam position sensors. it would really help to hear of anyone having had the issue with the cel pointing to a LOW input bank one, as opposed to hi output since thats not what i'me getting. just changed my oil and cell occurred the next day. dont think "we" banged into anything, and car runs like a stung mule, though drive to shop cel will go on at 1.2 bar. thats all i got

any help would be greatly appreciated.

I had to replace on of my camshaft position sensors. It's a pretty easy job. Diagnosing it took some thought, though, since the code I got was not actually for the sensor and the factory service manual made no mention of the sensor being the possible cause. I just monitored those inputs in the Durametric and made an executive decision to replace the sensor with positive results.

You can get the sensor from advance auto. Order online with a coupon code from retailmenot and pickup in store.

Executive decision! I like that. Since my 30$handheld reader is pointing to those I AM trying to avoid the 100,per hr diagnostic route since if it IS as simple as a bad 50$,part I can swap it with my bud in the driveway. I don't trust shops any more than necessary.

Besides the cel(s) did you have any symptoms??, I have zero.
Thx BTW.....

Nope, no symptoms. It ran absolutely perfect... I even beat a C6Z while monitoring on the durametric. The inputs just weren't jiving with the way it was running. I noticed the inputs would get worse as the sensor heated up.

That dovetails with it seemingly occurring at 1.2. If you're right you're gonna be 2 for 2 with my recent bearing plate r&r (,good call ) and on my next Xmas list. Lucky you ha..
All kidding aside... Thanks.

Let's hope. If there's anything my wife will say I live for it's being right.

i'll still install the CPS ( since i bought it wtf! ) but just add this to one more niggling feature of a low battery and how critically important to the proper running of ALL elec functions of this car a fully charged battery is! i figured driving it daily was enough and forgot my own advice to trickle it bi-weekly whether it "needed" it, or not.

just some added anecdotal info....these cars are voltage HOGS lol

Interesting. I'll have to keep this in mind if I get any low input codes.

hence the term "throwing parts"! I ordered it before I even bothered to trickle charge. so far not ONE cel & "drive to.. NOT" lol

gotta love pelican. order Friday had it sat by 2 pm!

I had the CEL too - I reset my codes and it didn't come back. However, in my research I think I remember reading that the car does something like 6000 start cycles before it will check/throw the code again.

Come to think of it though, my battery might have crapped out shortly after that and I replaced it with an AGM Bosch

i was getting/clearing the cel about 10x a day. since charging ( car is trickling after my daily sprint as i type ..

it has yet to return. hoping, since i dont feel like yanking out the intake etc even though i have the new part already. it literally suggests that a low battery will throw this specific code "p0342 CPS low input", so i'm not in the least surprised. just pissed as my battery isn't yet a year old ... grrrr.

Perhaps a high output alternator would help?

Do you have a stereo with lots of amps or anything? Maybe the voltage regulator is going out?
