I've been running with a CEL code 54 for the past 2 years. Does anyone have experience with this code? What did you do to correct the problem?

 

Is this on a B16?

 

yes

 

Whats the setup?

Obviously you're running an ECU that is looking for a CKF - do you have a CKF mounted and plugged in?

 

if it is an ob2d engine, it probably needs a CKF sensor. put an AC volt meter on it and crank it. if you have ac current the sensor ir probably good. if not chances are it needs the CKF sensor.

 

The weird thing is that I've never even touched that sensor ever.

I did buy a brand new CKF sensor from Honda awhile back, but I did't have a crank pulley tool to get to the area where the sensor is located. I intended to order a Moroso crank pulley, but I had to buy some other stuff for my car instead. In any case, I ended up returning the sensor to the dealer.

What's the easiest way to get to the CKF sensor without the tool?

Can this sensor just go bad by itself?

 

Before you go replacing stuff, just make sure the simple stuff is all good. Check the wires, plugs/harnesses etc. Could be like the VSS and the plug came loose or isnt making full contact and now its throwing a code. Easier to check that stuff than it is to pull your crank pulley and all that fun stuff.

 

But the problem is there's no way to reach or even see the sensor and its wires/plug without taking things apart. It is located in a virtually inaccessible place.

Any tips on getting to the actual sensor? I think I'm just going to go ahead and replace the damn thing. The CKF sensor itself is cheap, only about $30.

Well...c'mon now - the wires have got to be within reach - they eventually do go back to the ECU.

If you have a voltmeter, throw it on the DC scale and check for pulsing while the engine is running.

If you reset the ECU, does the code come back immediately - or do you have to drive awhile?

If you reset the ECU and turn the key 'on' and immediately get this code, then there is something electrically wrong with it.

 

I think the CKF sensor wires must have gotten cut by my AEM alternator pulley belt.

A new replacement CKF sensor will be on there soooooooooon.
