The CEL in my Jeep has been on for a while, I knew that the downstream sensors needed to be replaced from checking the codes a couple months ago. Finally got around to replacing them with Bosch sensors a couple days ago. Now that I've done 2 or 3 trips with it, the CEL is back on. Checked the codes and it's showing P0135 P0141 P0155 P0161 which relate to all 4 of them complaining about the heater.
Any ideas where to check? The upstream sensors were both replaced with Bosch sensors last summer, approx 5000 miles ago. No codes back then.
