P1290: Unleashing The Mystery Behind This Automobile Fault Code
The P1290 fault code refers to a low input from the Cylinder Head Temperature (CHT) sensor. This sensor is located in the cylinder head and is responsible for sending a signal to the Powertrain Control Module (PCM) to indicate the temperature of the cylinder head. When the temperature exceeds 126°C (-258°F), the PCM disables four fuel injectors at a time.
This is done to prevent further heating of the engine.
The PCM alternates which four injectors are disabled every 32 engine cycles. The four cylinders that are not being fuel injected act as air pumps to help cool the engine. If the temperature goes even higher, exceeding 154°C (310°F), the PCM disables all of the fuel injectors until the engine temperature drops below 154°C (310°F).
This is a safety measure to protect the engine from overheating. In summary, the P1290 fault code indicates a low input from the CHT sensor, which can lead to the PCM disabling fuel injectors to prevent engine overheating.
