marc fisher helped me check them and I have the following:

P0420 H & C TWC low efficiency bank 1-A
B0361 H & C Left Actuator feedback short to GND
C2115 H & C Left rear TPM sensor malfunction

I have a handful of other codes but they're all "H" so I don't need to worry about them, right? what do the "H & C" codes mean? please don't tell me I need to take her to the dealership!

thanks.

Look the codes up on the above site.... "H" is history "C" is current. Sounds like a dealer run. Just don't go to the dealer Marc is using.

DTC P0420 is your major concern. it indicates your catalytic converter is not working properly.
DTC B0361 is the HVAC. something to do with the actuator providing the proper air mix door position.
DTC C2115 indicates the LR wheel sensor is not transmitting info to the receiver.
as you requested i will not tell you that you need to take her to the dealer. :)

 

P0420 is set by the Powertrain Control Module (PCM) monitoring the difference in output signals between the Heated Oxygen Sensors (HO2S) # 1 and #2 (on each side of the Three Way Catalytic Converter (TWC)).

You may have damage to the converter, check for dents, severe discoloration (excessive temperatures), holes, etc.

You might also have a leak and loose or missing hardware.

Check that the HO2S sensors are secure, and that the electrical connection is good. Also check that the wiring is not damaged or contacting the exhaust.

As to not worring about the "H" codes, it is nice to be an optimist. "H" may be nothing, or they may be an indication of an intermittent problem on its way to something bigger. Rare for a Corvette to "fix" itself. :lol:


Sorry not much help.

thanks! already got the replacement pressure sensor. the catalytic converters were taken out with the headers install. actuator? proper air mix door?

 

the actuators are the devices that operate the opening and closing of the "doors" or "flaps" that directs the air flow out into the car depending on the setting you select, i.e. defrost, upper, or lower.

 

so that has to do with airconditioning or engine? sorry for the stupid questions.

 

it has to do with the heating and air conditioning(HVAC).

 

thanks for your help! :cheers:
