I had to replace my 'burned' 2007 Fit engine head due to a radiator cooling fan relay going wrong. Did all the valve adjustments, etc accordingly. Now when RPM's hit near 4K during acceleration, the rpm limiting kicks on. Checked at the Honda dealer and a vtec sensor problem code was obtained. Replaced the vtec oil pressure sensor and still having the same problem.

Pls kick in your inputs...... I'm miss my FIT pep!

 

Hey F.Lr.,
Where is the over rev. sensor located? And what / how does it sens rpm's? I ain't doing alot right now so I'll check my info get back to ya. To see anything that may help.

the sensor i replaced is the 75 bucks oil pressure sensor. There are 2, located at the 'rear of the engine' (looking from the front of the car, located toguether at the far right side of the head. What call my attention is that according to the pcm code, the vtec is not jumping in due to low oil pressure. This is why the rpm limiting kicks in. When replaced the oil prsr sensor, there was no change in the hesitation the engine makes when getting to the 4k rpm while accelerating.

 

Bump, if this problem could someday happen to me I'd love for you to find the solution. :]

 

The sensor associated to the vtec is the TDC

 

Was reading another honda rsx forum and someone's car was cutting out @ 4k also and the answer for him was to pull the ECU fuse and he said that fix it. Now this is a rsx that's older tech. than our ecu but it's what worked 4 him. the pic is the tdc sensor for the 07 Fit.

Thanks for your input. Will do and post the results
