Imminent Crankshaft Position Sensor (CPS) failure in 2016s?

Seems like there have been a lot of premature failures of the CPS on the 2016s. Makes me think that Toyota sourced some cheap-ass China parts for the CPS or something. I wonder if Toyota is aware of this? Would they issue a TSB or recall for this or would they just try to cut costs and hope that many would fail outside of warranty when they'd be off the hook.

I rely on my truck to get me deep into and out of the backcountry. Would be quite an inconvenience if this happened on an isolated forest service road. Although with the growth in Colorado, it's getting pretty hard to find true isolation.

Anyone know if Toyota is putting in the same CPS or if they're replacing with a more reliable model? I know warranty wouldn't cover this, but if I see many more of these reports I'd almost consider paying to have the sensor replaced if Toyota has upgraded.

 

Yeah, I'd hope so. I'd imagine having a mis-timed crankshaft could jack up the engine a bit and maybe cause some significant wear once the sensor goes bad? No idea, as I'm not a mechanic. I could be totally full of shit, but I'd rather not have to get stranded and go through the rigamarole...

If anyone who has had this issue could chime in that'd be sweet... are they replacing like with like or is there maybe an upgraded sensor? I guess that information may not even be public knowledge at this point.

Is this something that's pretty easy to do? I replaced the O2 sensor in my POS Nissan Altima, but this seems like a more critical component and I'm minimally mechanically-inclined.

 

Not to mention the guy who just got a new truck because the dealership apparently couldn't figure out it was merely a bad CPS before it was too late. I think he said they replaced the head gasket and a bunch of other stuff that I would not want a dealership tinkering with!!!

How many is "a lot of premature failures"? Seen 2 or 3 posts about it.

 

Yeah .. those parts in my experience are made in Japan .... unless I see otherwise I'm going with a very integral part of my engine should be a quality part.

Doesn't make sense to cut corners on a vital engine part to me.. but I'm a common sense sort of guy with some of electrical engineering experience. Bean counters on the other hand ...

Electrical engineers will build with the BEST parts available. I trust Toyota on that. I've actually banked on that.

 

Yeah, I don't want to get it replaced if it's the same part anyway... I'll probably roll this dice.

And for the guy who says 2-3, I've seen more like 6-7 over the past few months. It's definitely probably the most common failure I've seen so far...

 

I'll remind you of a quote from a movie which pretty much says it all...

A new car built by my company leaves somewhere traveling at 60 mph. The rear differential locks up. The car crashes and burns with everyone trapped inside. Now, should we initiate a recall? Take the number of vehicles in the field, A, multiply by the probable rate of failure, B, multiply by the average out-of-court settlement, C. A times B times C equals X. If X is less than the cost of a recall, we don't do one.

 

There have been other CMP sensor TSB's that require shimming, but most have been the stupid Subaru 2.0 (FRS) D4S engine, I had the same issue with my previous Subaru, They are extremely sensitive to air gap clearances and a minor defect can cause issues.

I've yet to see a model where replacement of the sensor doesn't correct the issue.

 

I've thought about carrying one as a spare. I don't know where it's mounted on this truck, but having one in hand could turn a ruined trip into a few hours or inconvenience.

I haven't found one listed for the 2016, but it looks like typical prices are around $40-$70.

 

If more than 1 person has an issue on an automotive forum, Its a major issue and there should be a recall immediately.

 

Does anyone have a picture of what the CSP sensor looks like or where is is mounted on the 2016?

 

Except sites like this tend to draw in people who have issues. It's a lot like going to the doctor and noticing that most of the people in the waiting room are sick. "Must be something going around". But it's a doctor's office and that's where people go for answers to their problems. It's the same around here. "Must be something going on".

Maybe it is....maybe it isn't. But like any issue...unless there are enough failures to trigger whatever red-flag system Toyota has in place...things like the occasional bad CPS will be replaced on a as-needed basis.

 

Those of us with the 7.3l Powerstroke did just that....it was a weak link on the motor so I kept one in the glove box. Had to change it once as I recall.

 

The description in Fight Club was incorrect. Actual "analysis" was done by Ford in regards to the Pinto in a rear collision, where the bolts on the rear axle can pierce the fuel tank. Anyway, the way safety reporting and recall decisions are handled by NHTSA have changed significantly since then.

 

Wait...you are saying a movie about a ficticious fight club misrepresented a fact like that. Who knew?

 

Toyota uses a common CKP sensor across many models. Since the 2016 parts catalog isn't online yet, I can't confirm if 2016 still uses the same part as 2005-2015. There's been some speculation the sensor's proximity to an exhaust pipe in 2016s may be causing the failures. So the solution may not be a redesigned sensor, but better heat shielding.

 

Haven't tried soap made from human lipo fat to confirm the other "facts" from the movie either.

That's something else we don't know, was it the CPS that actually failed or the install?

CPS do fail, but very seldom, I can only think of a few in my life, but from different makers, one Ford, Olds, and one other.
To get a spare for the wilderness (or a weekend) is not an expensive part to have, based on the scary stat info we have so far, but to do the actual R&R might be a challenge, if we don't know the proper install for this application. I know I don't.
Perhaps someone with an active TIS account can download the installation instructions for the ’16??
Cheers!

Please can someone do this.
