What does P0731 Mean? OBD-II Code P0731 is defined as a Gear 1 Incorrect Ratio The purpose of the automatic transmission is to match the engine's optimum power and torque characteristics to the driver's desired rate of acceleration and speed by auto-selecting different gear ratios or 'speeds' to power the wheels. Code P0731 When the code P0731 is set in the Powertrain Computer, it means that the Powertrain Computer or PCM is seeing greater than a specified RPM difference between the rotational speed of the Input RPM Sensor and the Transmission Output RPM Sensor in Gear 1. This can occur during shifting or when driving at steady speeds in the same gear. It often implies that the transmission is slipping. engine code P0731P0731 fixobd P0731dtc P0731obd code P0731obd2 P0731P0731 car codediagnostic code P0731car code P0731check engine code P0731fehlercode P0731P0731 fiatcodigo P0731codigo falla P0731P0731 kody b??dówcodigo de falla P0731 What are the common causes of P0731 ? Rarely - faulty Powertrain Control Module (PCM-programming required after replacement) Rough running engine due to misfiring plugs. Many engines have misfire codes to indicate the cylinder effected, such as P0307 for number 7. A large vacuum leak would cause a massive amount of un-metered air to enter the intake manifold resulting in an overly lean mixture. View attachment 413 How do you troubleshoot P0731 ? Like the all engines, the car engine system employs specially developed hydraulic lifters (known as switching roller followers) for the P0731 code intake and exhaust valves. The lifters can be collapsed by disengaging an internal locking pin. The locking pin is disengaged using solenoids to alter oil pressure fed into the lifter.
