That's normal. It's a way of protecting the motor. Engines with floating wrist pins don't like to rev past 4k while under no load. It's too hard on them.

 

Is the floating wrist pin problem a new thing? My 2009 Camry with the same engine lets me take the engine all the way to red line in park, and I've driven several other Toyota's with the same engine that do not have this limiter either.

I thought the limiter in park had to do with emissions control, and is why a lot of new cars today have a park or neutral limiter set at a low RPM.

I do know that there is also another purpose for limiting the engine speed in park, and that is when the engine is cold. But engines that do this will most often let you open it wide open once it gets up to operating temp. BMW even has a dynamically changing red line (The RPM gauge even changes) based on engine temperature.

EDIT: Just thought of something else. Toyota may be doing this on all of their new cars because of the floor mats causing stuck gas pedals fiasco. Throw the car in neutral and the lower RPM limit kicks in to prevent the engine from blowing up.

 

My Ford Transit does this too...makes it hard to do neutral drops!

 

Neutral drops :shakehead:

I hope these are lease cars..........

 

My rev limiter in park is only 4K rpm, is this normal or should I take it to the dealer?

Are you trying to launch your car from a neutral to drive while revving at very high RPM? I did that a few times on rental cars. Trust you know it is very hard (can be catastrophic) on your transmission. Are you still in high school?

 

If the person is they are just going to go backwards in a hurry too. If you want to spin the front tires which I don't know.why anyone would want to in a camry just set the park brake in drive and floor it I guess lol.

 

 

im just waiting for one of you guys to float a valve reving the engine without any load on it like that.

 

2004 Neon SXT w/ 4spd auto had a rev limiter at 4K as well if in park.

Not sure why manufactures do it. Maybe one because there is *usually* no reason to revv an engine at idle except for noise and extra fuel consumption. Of course while driving, there is a reason why you rev an engine (i.e. to get to a certain speed faster in lower gear). Also I suppose it is there to prevent dumb stuff from happening with people because they accidentally went into neutral while shifting to a different gear in a parking lot (i.e. R to D or D to R) and have their foot on the gas revving the engine only to then put it in the right gear suddenly as a panic response. Prevents neutral drops in either reverse or drive maybe...

 

Mine is, lol. Granted I have yet to try a drop in my Ford, as its tranny already had issues and need major service at just 40k miles, but that's what happens when you install Focus drivelines in a cargovan...

It is fun to roll (in neutral) through parking lots and neighborhoods, foot burried, bouncing off the 3200rpm limiter doing 5mph or so.....so fast and furious!

 

Why in the world would you WANT to rev an engine over 4000 rpms in park?

 

See my previous post.

A lot of people like revving their cars in park or neutral to see what the exhaust, engine, and intake sound like without a load.

Car reviewers do this often in their video reviews, but since many cars today have a limiter in park and/or neutral car reviewers are unable to get a good recording of what the car sounds like unless they try and record while driving, which is much harder to achieve due to the increase wind and road noise.

Now, with this being a Camry, unless you have aftermarket parts installed, it really isn't worth listening to. But with the right setup, the 2GR-FE can sound very good (Go listen to a Lotus Evora, it uses the same engine as the V6 Camry).

I just want to add that there could also be other reasons related to diagnostics or repair work. For instance, checking for vacuum links or listening for a specific noise from the engine bay that only occurs at a higher rpm. Although 4k rpm is actually relatively generous. I've seen some other cars that won't let you rev the engine at all or just limit it to 2K rpms in park.
