L1H1 O2 sensor wire colors
Trying to find out what the 5 wires on the L1H1 NTK O2 sensor are for, such as which ones are heaters, etc. The colors on my sensor are:
White Yellow Orange Red Black This was an engine swap, from obdo to obd1, with a conversion harness and now I need to get the O2 connected to a PO7 ecu which I just obtained. No plugs or harnesses available to me, just wanted to know what the colors on the actual sensor side were for and then I could find the proper pinout on the ecu. |
Got this from NGK
Yellow: Heater Ground (-) Orange: Heater Power (+) Black: Common Ground ( for IP and Vs ) White: IP circuit (Current pumping) (+) Red: Vs reference (+) Now, could anyone guide me to which pins these would go on the PO7 ecu? |

Last page of that PDF will show you what you need to know. |
What pdf? Is there one located on that web link, I do not see any pdf files attached anywhere?

Look again, it's there now, I just had image tags on it by accident, lol.
