I've had my 02 Accord EX, AT, 4 cylinder VTEC for about 5 months and I am ready to trade it. None of the Honda Forums have been able to confirm a problem with the hesitation exhibited by me and others with the VTEC. I am disappointed that this appears to be a common issue with these vehicles. After component tuning and routine maintenance, I am convinced that the transmission ECU and the throttle position sensor has a lapse in 2 way communication which allows a brief hesitation after slowing, then accelerating. I've read that the 6 cyl. engines have the same issue.

Anyway, if someone finds a solution to this hesitation, let us know.

Thanks, Jeff

 

Welcome to the world of overly complicated vehicles. They arent getting any better.

 

My guess a trans. but maybe you could be a little more specific.

Sorry no solution here but that just seems to be a common problem with autos in general. I have a 04 4runner that does that sometimes. I will be slowing to make a turn off the road and right before I almost come to a complete stop the and hit the gas again the tranny hesitates downshifting. I recently drove a land rover lr3 and noticed the same behavior but it had a violent lurch instead of a hesistation.


By the what do you mean with the vtec?

 

your vehicle is auto, that, unfortuanely is the problem. I have a 91 civic with an auto tranny, and my sis has a 92 accord. Both of these cars do what your talking about, its very common. You may be right about your diognosis, but if your familiar with the honda auto trannys you know that its not like a conventional automatic which has plantary gear sets and clutch discs but rather it is a conventional manual gearshift setup with a complicated valve body that controls shifting. Thes trannys are crisp when very fresh but they all develop problems down the road and alot of it has to do with how it is designed.

 

i missed that it was an 02, im very sorry, but what i said is true about honda auto trannys, id get a 5 spd. I would look into your dianosis and confirm thats working properly.

That's not really how it works. The sensor is fed +5v, and the variable resistance allows the ecu to see a 0.45v - 4.50v range. To use the term communication makes it seem more complex than it really is.

I have experienced that with all Honda autos. Slowing rapidly and then getting back on the gas quickly doesn't give the transmission time to downshift, so it has to sort itself out. Happens on the cars off the truck with 0 miles, happens on my 89 civic with 200k miles. Sorry.
