Check Engine Code P0141 on T-100 (1 Viewer)

[sitnlow4life]

Hello

I have a 1996 T-100 3rz automatic

Check engine light cam on last week, Scanned truck and got 1 code P0141
Oxygen Sensor Heater

From the info I gathered it is the Front or Pre-Cat oxygen sensor

I ordered the Denso replacement for this application, installed it on Friday night , wiped the code and started driving it.

The next day the check engine light came on again , scanned the truck and once again we have P0141.

Thanks
