My 2007 Chrysle Sebring was Coding a P0300 General Misfire and I found out it was the converter which I replaced along with both O2 Sensors. It then started coding a P 0135 - O2 Sensor Heater Circuit Malfunction (Bank 1 Snsor !0 and I cleared it now it is coding a P0032 - HO2S Heater Control Circuit High (Bank1 Sensor!) any recommendations for repair. I have replaced all the other sensos and hae a new ECM but have not put it on the vehicle yet.

Vehicle: 2007 Chrysler, Sebring, 2.4 L

P0032 Oxygen sensor Bank 1 Sensor 1  heater circuit high

P0135 Oxygen sensor Bank 1 Sensor 1 heater performance

Circuit high code are code that mean poor to no connections.  When the code condition first occured it occured as a P0135 this is the heater circuit, when you cleared it , The ECM now looks for open circuit, short circuit, and grounded circuit. and it coded a open circuit, this can be from a wrong type of 02 sensor used , or poor connection.

 

 This is a 02 sensor someone installed on the their vehicle, it coded a 02 sensor heater control circuit high, what happen here was the connection that are suppose to be crimped was missed and resulted in a heater circuit high code condition , what the 02 heater does is bring the 02 sensor up to operating temperatue faster allowing faster fuel control .
