The Volkswagen Code P1296 is an indication of a cooling system malfunction, a common problem in many Volkswagen models. The Engine Control Module (ECM) uses the intake air temperature as a replacement value for an engine start when a Diagnostic Trouble Code (DTC) is stored in DTC memory for the Engine Coolant Temperature (ECT) sensor. This can lead to further issues with the cooling system caused by failed engine coolant temperature sensors, open circuits, shorts to B+, sensor circuits short to ground, or ECM failure. It is important to identify and address the issue’s source to ensure the vehicle’s safety and longevity.

Causes and Solutions for Volkswagen Code P1296
| Cause | Solution |
|---|---|
| Failed engine coolant temperature sensor | Replace the sensor with a new one |
| Open circuit or a short to B+ | Check wiring and circuit for damage |
| The sensor circuit is short to ground | Check wiring and circuit for damage |
| ECM has failed | Replace ECM with a new one |
Failed Engine Coolant Temperature Sensor
The Volkswagen Code P1296 indicates that the engine coolant temperature sensor has failed. This sensor is necessary to accurately measure the temperature of the engine coolant, which is essential for the engine to run properly. If the sensor fails, it can lead to further damage to the engine, so replacing it with a new one is important.
Open Circuit or a Short to B+
The open circuit or a short to B+ is a common issue when dealing with Volkswagen Code P1296. This issue occurs when the wiring or circuit has been damaged, and it can prevent the engine from running properly. To fix this issue, it is necessary to check the wiring and circuit for any damage.

Sensor Circuit is Short to Ground
Another common issue is when the sensor circuit is short to ground. This occurs when the wiring or circuit has been damaged, and it can prevent the engine from running properly. To fix this issue, it is necessary to check the wiring and circuit for any damage.
ECM Has Failed
The final cause of Volkswagen Code P1296 is when the ECM has failed. The ECM is the engine’s brain, and if it is not functioning properly, the engine will not run properly. To fix this issue, replacing the ECM with a new one is necessary.
Conclusion
The Volkswagen Code P1296 indicates a cooling system malfunction, a common problem in many Volkswagen models. It is important to identify and address the issue’s source to ensure the vehicle’s safety and longevity. The potential causes for Volkswagen Code P1296 are a failed engine coolant temperature sensor, an open circuit or a short to B+, a sensor circuit that is short to ground, and an ECM failure. To fix these issues, replacing the sensor, checking the wiring and circuit for damage, and replacing the ECM with a new one is necessary. Doing this ensures that your Volkswagen is running properly and safely with the Volkswagen Code P1296.
