P1133 = Heated Oxygen Sensor (HO2S) insufficient switching bank 1 sensor 1 (Rear Bank)

You might want to check your splicing just in case it came apart.

Once you splice in youre wiring harness youre gonna want to get some heat shrink covering for thr bare wires cause, water and dirty get into there, Youre gonna have short in youre wiring, All some those butt connectors are no good for that either, Just twist the wires together, heart shrink them youre set.

Good Luck.

well, I am not sure about a 2.2 on a 98, but I have a 2.4 twin cam 98 and the upstream (one on the manifold) is not a heated o2. I am almost 100% for sure yours is not either. If it has 1 wire, then no, it is not a heated o2...

How did you splice it? Solder the wires or twisted them together?

those are no good. they've corroded, you need to cut, solder , and heat shrink it.
