Details of the Dodge p1196 OBD Code

Dodge fault code P1196 relates to the oxygen sensor signal being slow to respond.

Dodge OBD code P1196 means that the Engine Coolant Temperature (ECT) sensor 1/2 correlation is out of range.

This code is triggered by the Engine Control Module (ECM) when it detects a discrepancy between the readings of the two ECT sensors in the cooling system.

The ECT sensors are responsible for providing the ECM with accurate temperature readings of the engine coolant.

When the correlation between the two sensors is not within the expected range, the ECM sets code P1196. This code is specific to Dodge vehicles and can indicate a fault in the ECT sensors, wiring, or the ECM itself.

Mechanic’s Tech Notes

Dodge code P1196 relates to the oxygen sensor 1/1 heater performance issue.

To diagnose and fix OBDII code P1196 on a Dodge, start by checking the transmission control module (TCM) power and ground using a multimeter.

Verify TCM communication over the Controller Area Network (CAN) using a scan tool.

If communication issues are detected, reprogramming or reflashing the TCM may be necessary.

Additionally, visually inspect the wiring harness and connectors for any damage, and ensure connector pins are not broken, bent, pushed out, or corroded.

This thorough inspection will help identify and address the root cause of the P1196 fault code.
