Hey honda buddies..

Im new here.. & im desperately in need of help..


Engine - b16b type r

ECU - PCT 003

Vehicle - del sol


PROBLEM #1


Basically my engine redlines at 6800-7k rpm full throttle...

When i should be expecting 8k+..?


Check engine light is ON✔✔


And what i noticed is that both my o2 sensors are disconnected


Secondary o2 (2white,1grey,1black)

Primary o2 (2black,1white & 1green)


PROBLEM #2*


There no actual connectors/plugs on the main harness**NONE


So im desperately asking if all the wires go back to the ECU or which wire goes where


All help will be greatly appreciated..


Feel free to ask any questions..


Im from the Caribbean

Trinidad and Tobago

 

Sooooo, it's running...., but there's no plugs on the harness? I'm confused....

 

Hey buddy sorry if u misunderstood..

Update..
I opened up the loom beneath the intake manifold & luckily i found 4 stray wires with matching wire colour with the secondary o2


WIRES

Black - white stripe
Black - yellow stripe
Green
White

Unfortunately im not a

Sure if these wires work

& im still missing the single white wire for the primary o2...


Or can i connect both o2 sensor's white wire together.?


Plz help!!!

 

The wire colors you listed are for the primary O2 sensor. The 2nd O2 sensor wire colors are

White/red

Black/yellow

Black/white

Red/yellow

 

Hey thx alot bro

So i reconnected the 4 wire (primary o2)

And wend down n removed the secondary..

Noticed that 3 wires are broken clean off from the top of the sensor leaving 1 wire hanging...

So actually there's 4 wires on this sensor also... damn : (

WIRES

2 white
1 grey
1 black

Unfortunately i cant seem to find wires on the loom to reconnect...

Now where can this be connected to.?
Hmm.

 

You shouldn't need the 2nd O2 with the ecu your using just the primary o2is needed. Reset the ecu and see if the check engine light comes on once you hook up the primary O2.

 

Okay thx..
I reconnected the (primary) o2
CEL remains ON

I used the code light technique by jumping the 2 wires
The CEL quickly blinked once

code #1 - primary o2 sensor

Cam any1 direct me from here..?
