hey guys got a weird issue with my car. it wont rev past 5500 rpm no matter in what gear in either sport mode or automatic while driving. in part it just revs to about 4900 then hit rev limiter which i assume is normal. i have already reset the ecu and did the drive by wire throttle reset still the same. my snap on scanner did not pic up anything. is this normal?? any one else with this issue i have searched the forums and no one has my specific issue. car is a 2005 acura rl 3.5 170k

have you checked oil level? make sure it's at full line.

jmoney2001

yes oil is good

if oil level is good, then it may be the APP sensor?
does the RL even have an APP sensor?

jmoney2001

yes from my understanding its a fly by wire system. do you happen to know what the car hits rev limiter in park??

in park, it doesnt red line. the max RPM it reaches is like 5500.


redline is 7200 RPM.

if the car doesnt reach the red line, means either low on oil or APP sensor.

i will have to look into the app. my car in park will only reline at 4900 rpm. i know its supposed to be lower just didnt think this low

dont worry about what it does in park. because that's the max RPM it reaches.
you should ONLY be worried about why it isnt going to redline 7200 RPM in drive and under load.

vtec starts at 5500 RPM. the cam switches profiles, so if low on oil it wont go into the HIGH RPM range.
also, may be vtec actuator.
may be APP sensor.

jmoney2001

how would i go and check to see if vtec actuator is working
