98 DX honda civic with a B20 swap CEL
I need help ASAP. So I just recentlu bought a 98 Hatchback and was told it had a B20B swap done. It is currently throwing codes "P0113, P0135, P0141, P1337, and P1508"
I took a look at the exhaust and I didn't find any place where an o2 sensor would go into it. It has a full 4,2,1 Header. No Cat. And I just wanted to know what I had to do to get rid of these codes.
I have no idea if its running the stock ECU or not. Please help. Will not pass NJ inspection becuase of the CEL.

Re: 98 DX honda civic with a B20 swap CEL
P0113 is intake air temp sensor. The B20 uses one in the intake manifold and the Civics is located in the air box. Either they never hooked it up or the wiring is damaged. You need to either get a plug for the B20 or find the Civic sensor and put it into your intake arm
P0135/P0141 are for primary and secondary 02 sensors. You need to have a cat installed and a bung put in place before and after and plug the primary before the cat and secondary after. You'll probably need to extend your 02 sensor wiring
P1337 is crankshaft fluctuation sensor. The B20 is more than likely JDM and doesn't have this sensor. You'll either have to bypass (google bypass CKF) or get a US B20 oil pump and convert your plug to two wire and plug it up.

Thanks so much. What about the P1508 one?

Sorry that's for idle air control. Previous owner probably didn't convert to 2 wire. Check this thread I made
