No Start Condition (Codes P0340, P0341, P0365, P0366)
 

Hello everyone, a few days ago as I left a meet my car lost power and then died on me. I pulled over and attempted to restart it but it cranked oddly and wouldn't turn over. I towed it home and pulled codes P0340, P0341, P0365, and P0366. I'm not sure if it's the camshaft position sensors or maybe my timing chain jumped a two-three teeth. I did swap the right intake sensor and put it on the left side but it threw the same codes. I'm curious if Toyota would cover this under the 6/60,000 warranty but I doubt it.

Here's a short clip of me attempting to start it.

I've also done lightweight crank pulley and a CF driveshaft if these may have played a role in jumping the timing or something.

Clip sounds like a timing issue and the fact you threw codes for both the A and B sensors is not promising! They may indeed try to blame the light weight pulley as it is part of the belt system.

It's weird that I'd only have a timing issue now. I wonder why there wasn't much leading up to it. Oh well, guess I'll be dropping the entirety of my income tax to get the timing fixed.

That is what happens when timing belt/chains jump or break. Not very often you get warning. All is good and then suddenly it isn't. Hopefully you didn't damage anything. I broke the belt in my turbo Talon and since they were an interference engine it blasted most of the valves through the head. It was messy. The bad news is that the FA 20 is also an interference engine. The good news is you didn't break the belt but just skipped it. It may be as easy to fix as popping a new belt on and making sure things are in the right place.

There are of course other things that it could be but that video is very telling. This is the very first case of this happening to a FA20 that I have read (there could be some I missed though) and I have to wonder if the pulley had anything to do with it. NOTE: I am not trying to start a another pulley debate here but it seems more than coincidental to me.

I just know replacing that chain replacement is gonna cost a ton in labor and I don't have the know-how or time to do it. The stock pulleys are going back on whenever I can get this thing into a shop.

How many miles are on your car?

It sounds like the timing chain to me too

Have you checked the plugs/wiring for your camshaft position sensors?

Only 57k.

Yeah, checked and cleaned all of them like a mad man.

How are you with a multimeter? Meh, it gets deep quickly. Best to cut losses.

I haven't really used one but I understand you can test voltages on the wires. I'm taking it to a shop tomorrow but I'll keep the thread updated in case this happens to anyone else.

Quick update: Turns out the timing chain broke entirely on the passenger side. I've been told there is definitely bent valves and possible damage to the piston heads. I don't know how it happened but it did.

:(

Pulley and driveshaft only? My condolences on your engine dude. RIP

It's all good, I'm taking it back to stock then it's gonna be covered under manufacturer warranty. Then I'm selling it.

my timing chain broke
 

My car just threw these codes and when opened up the timing chain and camshaft sprocket were broken per my local dealership.... 73k. Seems like a warranty should cover this in an unmodified car...what happened to modern car reliability let alone Toyota...? Subaru parts?

There must be an issue with some engines then. What year is yours and is it an FR-S or BRZ? I'd fight with Toyota or Subaru to get them to cover it. Because timing chains shouldn't be breaking, especially on a stock vehicle.

I'm calling Toyota tomorrow - apparently they are located on Cali but use central time... the dealership told me they no longer assist with this process but just give the number to call... I will update as I find out more. Right now I'm being sold more labor to see if the internals are damaged vs. putting in a junk yard refurbished engine for like 5k + labor...

Sooooo...my engine is destroyed and Toyota considered helping me financially but then backtracked after giving me an initial offer of $2500 towards the repair or replacement. It took forever (I'm at week 4 of a rental car) and it's all very cryptic but I can only assume it is because I couldn't find the complete service records and its past warranty. Toyota doesn't actual provide any kind of information or report (although I'm continuing to ask). They just said, through the dealer, we're not giving your any money towards replacement or repairing your car - it left a bad taste in my mouth. So I'm stuck purchasing a rebuilt engine for a boat load of money... You know it's interesting because the service manual specifically says that they won't deny a claim if one doesn't produce perfect service records but I guess since it's out of warranty they do...? So much for Toyota reliability...

I think you can just total it on your insurance, pay the deductible and be done with it. I bought a BRZ with 78k miles on it and I'm praying this crap doesn't happen to me. I can't even understand what causes this to happen.

If it's out of warranty of course they'll deny the claim. It's out of warranty.

As for the reliability- a couple cases on an internet forum aren't exactly a pattern failure. 1 isn't being covered by warranty because an aftermarket part probably caused the issue and the other isn't covered because it's out of warranty. I'm not looking to turn mine in as soon as the warranty is up because of this. The fact that there are so few threads like this is encouraging for me. Check out some Focus RS/ST forums....

If you still have this car your in luck! They just issued a recall on 2013 86's for valve spring failures.
