2007 Dodge Caliber P0032 and P0113 Fault: O2 Sensor Heater Circuit High & Intake Air Temperature Sensor Issue
I'm experiencing a serious performance issue with my 2007 Dodge Caliber. The vehicle does not accelerate smoothly, even after I replaced the oxygen sensor (O2 sensor) connected to the exhaust and the fuel pump casing. Diagnostic scans have revealed two trouble codes: P0032 - O2 Sensor 1/1 Heater Circuit High, and P0113 - Intake Air Temperature Sensor Circuit High. Despite these repairs, the problem persists. I've already invested significant money in troubleshooting this vehicle and need accurate guidance on what could be causing these faults. Can anyone provide insight into possible root causes or recommend next steps for diagnosis?
Could you please confirm the exact year, model, and engine type of your 2007 Dodge Caliber? Using an OEM Mopar O2 sensor is recommended—aftermarket parts can lead to inconsistent readings. For accurate diagnosis, it's important to know your vehicle specifics. Can you access a digital multimeter (DVOM) and refer to the official wiring diagram? Alternatively, having a diagnostic scanner that provides live data would greatly assist in identifying whether the sensors are functioning correctly. Note: Retrieving fault codes alone is not sufficient for proper diagnosis—live data and system behavior analysis are essential.
