Good afternoon,
please I owned 2006 Honda Civic Coupe, if I should drive it for 14-15 minutes at 100-105km/h on high way, the vehicle will fail to accelerate again and the RPM will remain at 2,000rpm after placing the gear shift on Neutral, if I turn off the engine and wait for some minutes it will work normal again. i have replaced the electronic throttle body, change the temperature sensor but the problem still remain. please i need help.

 

scan for codes

 

i scanned for code, and he asked me to replace coolant temperature sensor and I did but the problem still persist. Is it possible for the fuel pump or key battery low to be causing it, I discovered that the key battery is poor.

 

The key battery is only going to affect how you get in and out of the car by unlocking or locking the doors.

Have you check the TPS sensor?
