hey guys i have a JDM b16a and ecu is saying code4 i no its crankshaft position sensor i just dont no what to do to fix it and would that make cut out at 3000rpms

 

dizzy probably took a crap on ya

 

no it good i guess i am just going to get a nes crank position sensor so its a jdm b16a what car can i get one for that will work

 

its inside the distributor. is the timing belt on correctly?

 

You have to buy a whole new distributor assembly to replace the crankshaft position sensor.

Here is the Factory Service Manual to see what the issue is.





The pics are kinda small, if you can't read them let me know, I will send you the PDF file for the troubleshooting.

 

no i cant read them thanks a lot guys if i would get a new dizzy tho would that work better and so guy told me that it was down by the water pump thats were the crank sensor was

 

hey a nother thing i just did the swap and its a dx so i had to re wire the dizzy plug on and all that with the pin for b10 b12 and to other pins i think it was 2 c pins

 

that guy doesn't know what he is talking about - on OBD2 engines, there is a sensor behind the crank pulley, however, it is not the CKP (Crank Position Sensor) but is the CKF (Crankshaft Speed Fluctuation Sensor) and is only read by OBD2 ECUs - you have a CKP problem and the sensor is in the distributor - probably not the sensor that is bad - more likely, the bearings for the distributor shaft are worn allowing the shaft to move laterally and causing the sensor to, in effect, short out - best get a different distributor - very common problem on B-series engines - most people that i know with a B16A carry a spare distributor since they are constantly going out

 

you could try switching the orange and white CKP sensor wires at the distributor connector and see if that fixes it

 

good advice ^

op: now that you made us aware you did a dpfi to mpfi conversion it seems quite possible that you simply reversed these wires. double check the wiring and make sure its going to the right spot on the ecu. if that's not the problem then the next step would be to replace the dizzy because the CKP is inside it.

 

thanks guys i got to looking and i forgot to sauder the one wire and it was not on good but all good now thanks a lot for the help guys
