Hello all,

Just replaced my O2 sensors , 99 D1 w/aels.
I had code p1183. So being proactive I replaced all 4. Now I have p1187 and p1193.

Scratching my head on this one.

Sounds like a short in the harness between the o2 sensor and the ECU. Trace it out from where the oil temp sender joins the harness.
