Should my engine rev with steering input

Fusion powered, with an M/T option....
Sorry ...couldn't resist...

 

I hope they give the MT fellas a knob to play with, on the 4th Gen electric Taco. Even if it’s only fake/placebo, it will help ‘em feel like men again.

 

A little yes

 

Those pedals look like Picasso Jeep grills.

Nice!!

 

I think that is cool AF!

 

I agree. I’d love to take if for a spin. I can’t imagine all that torque. Does it have an actual clutch?

 

From what I read, you have the option of driving it as a stick, or you could just put it in 3rd gear and drive it like an automatic if you felt lazy. Sounded as if it had a high torque capacity clutch and transmission too.

 

Cars did this before EFI and ECM's. Some older power steering pumps had vacuum lines running to them, when more PS is used, the vacuum would kick the idle up.

This is 100% normal. It's because customers complained steering effort was too much at idle. Now they complain the revs go up.

 

Just wanted to chime in that my 2018 taco does have the idle surge when turning the wheel. It's extremely pronounced and has almost caused me to hit the wall or another car. It usually happens in tight spots or parking. The truck jumps/lunges a little. There is a TSB for a reason.

 

Well a friend of mine also has a 2019 trd or but his is Auto trans. And while they are very different, I would assume the power steering systems are very similar or same. His steering seems much lighter and I wondered if mine seemed not as might due to the fact my truck doesn't rev when turning at idle.

He drove my truck tonight and he agrees my steering is stiffer.

 

Yes part of me thinks that's just the way my truck may be it only has 7000 more miles than my friends. And I'm at 18xxx miles. Also my brakes suck compared to his but that's a topic for another thread

 

Too late. You've just made it part of THIS thread.

 

I wonder if it's because yours is manual? When you have the clutch out its not as easy to increase the RPM's like it is for an auto car. Does it do with the clutch in or in neutral?

 

That's exactly why they did it but modern pumps are significantly more efficient (if even still belt-driven) and with faster computer response, the ECU only changes the idle as needed to maintain. There really isn't any need to increase pump speed to get the desired pressures anymore.

 

My Subaru's steering pressure sensor failed (blew out of the pump) so I blocked the port until my new pump arrived. It definitely makes a difference, the engine was nearly stalling during tight maneuvers.

My '06 Tacoma's idle surged pretty dramatically when the AC compressor kicked on and when steering. It was a common complaint back then with the automatic as it would push you ahead from a stop if your foot wasn't firmly on the brake pedal.

 

So there's a lot of responding-while-reading-only-the-title going on and from that I'm picking out a theme: OP says his RPM's are NOT bothered by steering input. OP drives a manual. Then come a bunch of responses from owners who say their RPM's ARE bothered by steering input, to the point where the truck surges. All these responses came from people with automatic trucks.

Here's today's nugget of interesting: If you own a manual 3rd gen, find someone with an automatic one or vice-versa. Pop the hoods. You'll notice that the steering systems are different. The automatic truck's steering is hydraulic-actuated, while the one on the manual is good ol' vacuum-actuated. Which unfortunately bogarts up the added space under the hood that would be perfect for an auxiliary battery. Maybe I'm off but maybe this explains the difference in these responses.
