CEL Problem

[BB DC294 NHCT]

I checked the blinks on the CEL and there are lots of codes showing. The code are 3 short, stop, 4 short, stop, and 9 short. Then 2 long 1 short, stop, 4 long 1 short and went back back again.

Correct me if I'm wrong, these are the codes that popped up:

3 MAP - manifold absolute pressure sensor
4 CKP - crank position sensor
9 CYP - cylinder sensor
21 VTEC spool solenoid valve
41 Primary oxygen sensor heater

Can someone give me tips on how to get rid of these problems. The car is running like shit.

what car sounds like a ground

dont they all share the same ground?

[NHSwaps13203]

na i just read closer. most of those sensors ground thru the ecu. Is this a motor swap? i seen a member on here have a problem on a ek because the caps werent on the plugs under the intake mani. they have distribution plugs with caps to connect all the wires

before there was no ground wire from the valve cover to the radiator support. i got grounded the wire and now it's good. the car is a civic dx with a sohc vtec swap.

the car was driving fine for a bit, same problem and codes showing up again. the ecu harness needs to get re-done again because of some loose wires. i'm getting on tomorrow.

problem solved. now it's good.
