Ok so my hhr suffered a fault gasline recently nd it set me back a good 7-800$ now the day after my much need oil change( car almost bone dry girl who sold it lied about oil change) my car wouldnt start back up when i had the oil changed the guy tested for codes and reset them. I remember seeing ps0012-17-19 003 and a few others that disappeared after initial oil change. So when i went to start the car the next day it cranked but would not turn over i purchased a new battery due to the car sitting a while from he bad gas lines and i installed a new crankshaft sensor which was def not ez not have wheel chalks walmart tools nd screw up jacks hoping the car dont fall nd crush me ive been reading the tech support pg and it says the codes im having are the intake and exhaust camshaft and crank shaft are not alligned and now im lost i dnt have much knowlege about auto mechanics but im trying my best if anuone can help me through this id appreciate it im not working nd spent my whole stimilus to get this car up and running so i can return to my work nd this happens im lost nd cant afford the overprice of a mech to scan it give my suggestions nd i still have the same issue if youve dealt with similar please help i did recently install a aftermarket radio and speakers but ive done this with my 16 malibu before totaling it and i had no electrical issues so im not thinking thats the issue it holds abouy 162k miles and i read a forum on bad water pumps and timing belts and camkshaft, all light inside work even radio lights flash on dash and the only light that stays lit is check engine light

 

to the forums!

Wow, that's the longest sentence I've seen in quite some time.

P0012 and P0019 are not HHR codes, perhaps you couldn't see them properly on the reader. https://www.chevyhhr.net/forums/prob...010-hhr-14259/

P0017 is related to the timing chain. If you replaced the crank sensor, which might have been unnecessary, the new sensor will need to be relearned.

You could remove the valve cover and inspect the timing chain, the timing chain needs to be tight, not just kinda tight.

 

Posting the year, model, engine size and mileage would be useful.

Also. Rewrite the post. I couldn't get thru but a couple lines. We'll try and help if we can figure out what you're trying to say.

 

I second what he said. Take the valve cover off, it’s not that hard, and look at the chain there should be no slop or sag in it.

The timing chain guides on these ecotec motors are the achilles heel, they wear out and often break apart. Your codes and symptoms sure do point that way

 

FMG , it’s a 2010, so it has VVT
162,000 miles
oil changes apparently not important
Sounds like a new timing chain is in order.
regarding P0017

Symptoms Symptoms of a P0017 will or may include: Malfunction Indicator Lamp (MIL) illumination The engine may run but with reduced performance The engine may crank but not start The engine may exhibit a rattle near the harmonic balancer indicating the tone ring is damaged The engine may start and run, but poorly Causes Causes may include: Timing chain stretched, or timing belt skipped a tooth due to wear Misalignment of timing belt/chain Tone ring on crankshaft slipped/broken Tone ring on camshaft slipped/broken Bad crank sensor Bad cam sensor Damaged wiring to crank/cam sensor Timing belt/chain tensioner damaged An improperly torqued crankshaft balancer A mis-built or mis-timed engine A loose or missing crankshaft balancer bolt The CMP actuator solenoid stuck open The CMP actuator stuck in a position other than 0 degrees Possible Solutions If your vehicle is new enough that is still has powertrain warranty, please let the dealer perform the repairs. First, visually inspect the cam and crank sensors and their harnesses for damage. If you notice broken/frayed wires, repair and recheck. If you have access to a scope, check the cam and crank patterns. If a pattern is missing, suspect a bad sensor or a slipping tone ring. Remove the cam gear and the crankshaft harmonic balancer and inspect the tone rings for proper alignment and make sure they're not loose or damaged or that they haven't sheared the key that aligns them. If they are properly installed, replace the sensor. If the signal appears normal, then check the timing chain/belt for proper alignment. If it's misaligned, check for a damaged tensioner that may have allowed the chain/belt to slip a tooth or several teeth. Also check that the timing chain isn't stretched. Repair and recheck.

P0012 pertains to camshaft problems also possibly VVT solenoids malfunctioning, not usually seen on an HHR

P0019 pertains to crankshaft problems also from a stretched timing chain

so, yeah, timing chain for sure

 

Ok i checked the chain, i had to give a lil tug for it to move so i will def say its tight. Because i cant
get it to start i cant align the chain wit the teeth markings

 

Thank you. So this actually makes alot of sense. I removed the valve cover nd checked the timing chain but i am unfamiliar how to move the chain. But the chain def appears tight and clean i dont know how to check the intake and exhaust solenoids to tell if they bad or good





Its tight could it have skipped a tooth and how do i line up the chain markings to the gear

 

Hhr 2010 2.2 liter LT 4Door 162,056mi
Replaced gas line, crank sensor, battery and radio. After a much needed oil change it stopped running when i got home nd wouldnt turn over after a few trys it stopped cranking all together.

 

This is proof the chain is in need of replacement, see the top guide between the camshaft actuators , see the top of the guide se broken away? Caused by a loose chain

 

The upper chain guide is half missing. The chain appears a bit loose; use a finger in the middle if it moves up and down easily it is too loose. the usual reason the guide gets destroyed is a loose chain. New guides come in a chain kit.

Whatever other symptoms a P0017 may present it is 98% a bad or poorly installed chain.

P0010, P0011, P0013 and P0014 all mean the VVT valves are bad.

As to the other codes; your memory must be failing, no such codes.

There should be a lot more evidence of oil in the chain area.
