I just put a b18b in my car but used all my obd-o parts,intake,dizzy all that.The car is throwing codes 4,5,6,7,and 9. Also it won't go past 3500 and its hiting some kind of rev limit. Please help.

 

4 CKP - crank position sensor
5 MAP - manifold absolute pressure sensor
6 ECT - water temperature sensor
7 TPS - throttle position sensor
9 CYP - cylinder sensor

you are in limb mode
get the cel fix then u be able to go pass 3500

 

I changed the dizzy and the computer but its still doing it. I bought a new throttle body withj the tps sensor. I'm going to change that and see if thats it, if not what should I do next?

 

your wiring is jacked up The Tps and map try switching the 2 plugs, as for codes 9 and 4 you need to check your wiring at the ecu there is a ORANGE and a WHITE wire that need to be moved from c1 and c2 to b10(orange) b12 (white)and the 2 blue wires go to c1(blue/green) c2(blue/yellow) check that that is all correct. and the code 6 check the plug under the Dizzy that single wire always breaks. hope this helps.

 

Yep, the wiring is all messed up. Or your alternator could be dead, bad alternators will make some weird things happen.

 

yea check ur wiring before u start replacing parts.

 

I did all the wiring when I put the b18a in and it fired right up and ran fine. Then I blew that motor up and installed the b18b and thats when I started having these codes. I know I bumped the map sensor when I put the new motor in but I don't know if thats the problem.
