Code P1153 Pontiac Description
The heating elements inside each HO2S heat the sensor to bring the sensor up to operating conditions faster. This allows the system to enter Closed Loop earlier and the ECM to calculate the air-to-fuel ratio sooner.
The Diagnostic Trouble Code (DTC) will be set when the ECM detects that the heated oxygen sensor rich-to-lean counts or the lean-to-rich counts are less than a calibrated value greater than 100s.
What are the Possible Causes of the DTC P1153 Pontiac?
- Faulty Heated Oxygen Sensor (HO2S) Bank 2 Sensor 1
- Heated Oxygen Sensor Bank 2 Sensor 1 harness is open or shorted
- Heated Oxygen Sensor Bank 2 Sensor 1 circuit poor electrical connection
- Low or high fuel system pressure
- Fuel contamination
- Faulty fuel injectors
- Exhaust gas leaks
- Engine vacuum leaks
How to Fix the DTC P1153 Pontiac?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
