Help: Y Civic Wideband O2 sensor can't work w/ K-Pro

Post by TodaCL7R » Thu Jan 27, 2011 5:36 am

I just purchase Civic D17 (Part# 36531-PLR-003) O2 sensor to replace my OEM O2 in order to work with Dual Harness TSX K-Pro.

I found out that the Civic O2 wires is not long enough to go thru the cabin, therefore i cut the cables & connect it directly to old/original O2 cables

Now K-pro recoqnize the New O2 sensor but throwing error code (O2 Heater Sensor Error) when i start the engine & datalogging. is there anything else that need to be check?

fyi, the A/F display shows 14:7 w/ ignition on (engine off), but later showing error 10:7 with engine on.

Please helps with any advise. thanks

Use an ohmmeter and check the resistance between the wires you have connected as the heater - it should be very low, like <20 ohms. If it's higher, it's miswired. Sure sounds like it's miswired though, considering it worked with the old one and because it's complaining about a heater circuit error.
