P0914 is a diagnostic trouble code (DTC) for "Gear Shift Position Circuit".

When a vehicle stores a P0914 trouble code, it indicates that the Powertrain Control Module (PCM) has detected a problem with the gear shift position circuit. Related codes include a P0915, P0916, P0917, and P0918 trouble code.
A P0914 trouble code denotes an electrical error in the gear shift position circuit. When the voltage coming from the gear shift position sensor varies too much according to the manufacturer's specifications, a P0914 trouble code is stored and the check engine light illuminates.
The most common reason for the storage of a P0914 trouble code is damaged or faulty wiring, connectors, or components within the gear shift position system. Blown fuses, a short to the battery ground, and a faulty PCM can also cause the storage of this code.
Symptoms of a P0914 trouble code include harsh shifting and, in some cases, the inability to shift gears. Another common side effect of a P0914 trouble code is a reduction of the fuel efficiency in the vehicle that has stored the code.
To diagnose and repair a P0914 trouble code a mechanic needs to use an advanced scanner and a digital volt/ohm meter. Using this equipment, the mechanic needs to perform the following:
Mechanics diagnosing and fixing a P0914 trouble code most commonly make the mistake of replacing the entire gear shift position system when the problem was with a much less expensive and easier-to-replace electrical component, connector, or wiring. In addition, failure to clear codes as they are stored can result in a failure to fix the problem causing the code, resulting in its eventual return.
A stored P0914 trouble code could only cause trouble with shifting, though in some cases the vehicle gear shifter might refuse to work at all. That is why it is imperative that you have a mechanic address the P0914 trouble code when it is first stored. In addition, conditions causing the storage of a P0914 trouble code can further damage the transmission if not diagnosed and treated.
To repair a P0914 trouble code, a mechanic should take the following steps after diagnosis:
