Code 54 keeps showing up on my check engine as soon as I start the car.

I checked and made sure that the sensor right by the oil pump was plugged in and it is so I am not sure how to remedy this.

Anyone that knows anything I don't about this problem please let me know.

UPDATE!

I cleaned the plug going to my crank angle sensor and that fixed my original problem. thanks to everyone who helped.

NOW I HAVE A NEW PROBLEM.

I am throwing a code for secondary o2 sensor. Problem- I don't have a plug on my existing engine harness for a secondary o2. Not sure where in the hell it went but maybe the previous owner cut it off or something.

Does anyone know where/how to wire in a second o2 sensor?

 

does anyone have a clue?

 

Are you using a itr ecu? Maybe something different between the two looking at the crank fluctuation sensor.

 

No noone has been able to tell me how to bypass or remove the immobilizer in the itr ecu

 

are u still obd2?.....type-r dizzy mite be diff for the other b-series dizzy....so convert to obd1 and get tuned and use a dizzy jumper harness so u can use a obd1 dizzy then u dont have to rewire the plugs and that should fix ur problem...

 

I have a P28 with crome but it's tuned for a b16 and runs this motor like crap.

I need a tune but I am waiting on cams from the guy I bought the motor from because they weren't in the motor like said and don't want to tune it till I get them. I just need something to limp around on till I get my cams.

BUT when I do drive around on the P28 I don't get the check engine light but that's only because obd1 doesn't look the crank angle sensor.

 

Does anyone have any help OTHER than use an obd1 ecu because that is obvious. I would like this thing to work the way it is supposed to first before I go tuning it on crome. Like I said I am waiting for my cams.

 

look on fffstech.net, I think that's the site. u can run the cyl pos wires to the cfk wires and bypass it

 

yea this can be done all you need is two quick splices i did it on my old mini me swap i'm at work and dont have the link on hand but i'll try to find it when i get home...but i hear that it doesn't work on all applications...solved my problem though

 

Only other suggestion i have is to order a basemap chip from phearable.net. I've had good success with chips from him.
