Increased RPMs on Honda Pilot?

Question

I own a 2007 Honda Pilot.

I was charging my phone, and for some reason happened to blow out the fuse on the charger and the radio. The Honda Dealership fixed it.

Ever since the fuse though, I have noticed that the car uses higher RPMs during acceleration.

It is hard to prove that the car is using higher revs to the Honda guys.

Does anybody have any ideas as to why this is happening?

Answer 1

The only thing that comes to mind on your concern is that Honda vehicles use adaptive learning to tailor the way the engine runs and the transmission shifts to your driving style. Over time the engine speeds will be adjusted in the memory of the on-board computer as it 'learns' how you prefer to drive the vehicle.

if you normally have a conservative acceleration the transmission shift program would be altered when that drive pattern is learned so that the engine runs at a lower rpm.

My theory, and its only that, is that the memory function for the 'learned' values of the computer is shared by the memory for the radio stations and other devices on the car. When the battery power is disconnected for a few minutes all memory is lost; for example, you have to reset the radio, reset the clock etc. They can be manually reset; on the engine adaptive learning however those values have to be 're-learned' by driving the vehicle.

the honda guys see a car that is operating within the normal range of operation; that's why they can't verify your 'problem'. They can't reset the computer values that have been learned so in essence the only 'fix' is for you to drive the vehicle to teach it how you like to drive it.

there is one thing you can try. Warm your engine to normal operating temperature then turn the car off. Then disconnect your battery for 5 minutes. reconnect the battery and then, turn all of the accessories in the car to off (radio, heater, defroster, etc.) then start the car without touching the gas pedal and let it run for 10 minutes. that will teach the car the idle values for your vehicle. that may help restore your lower rpm when accelerating. Its worth a try if it bothers you that much which it obviously does if your asking about it. If it doesn't help then give the vehicle time to relearn how you drive

hope that helps
