I'm getting a CEL and I took it to Advance Auto and they put the computer on it and told me its the O2 sensor, Bank 1 Sensor 1. I found one other thread that had good instructions with pictures for replacing the sensor on a '96 Taco, is it the same process for my 2003? Do I need to remove the cover on the manual gear shifter as shown on that thread? What is the level of difficulty?
Anyone know the P/N for this sensor. Looks like URDUSA.com is 234-9001 and the Toyota P/N is 89465-39895. Is this correct?
There are these recommended Denso sensors, brand new, for about $80:
