Well I just bought a 2000 Sunfire 2.2 and need to get it inspected...but my CEL is on and I am getting the following codes

P0113 - Intake air temp circuit high
P1870 Transmission Component Slipping
P0130 HO2S Circuit Closed Loop (CL) Performance Bank 1 Sensor 1

I have also gotten a lean code. For the 0130 Is that a problem with the sensor or the circuit? What about 1870? I think that appeared after I got a new gasket for my tranny fluid. And for 0113 Does this mean I need to replace the sensor? I has to disconnect it to put on my intake..maybe i hooked it up wrong and blew it out?

The 113 Air Intake Temp sensor you should replace or check where it's located in your new intake. I installed an AEM cold air system on my '03 Cav and drilled a new hole in the plastic tube, worked
just fine. The 1870 is odd, maybe the initial startup after the fluid change and pressure buildup? The 0130 i don't know, but it sounds like an ECM fault of some type. Replace the air temp, unplug the battery for a few minutes or clear the codes and see if the others re-appear.

bank 1 sensor 1 is your upper o2 sensor
