What is P0983?
The diagnostic trouble code (DTC) P0983 indicates a problem with the transmission range sensor circuit, specifically concerning the 'A' circuit. This code is commonly found in vehicles equipped with automatic transmissions, particularly models from Honda, Toyota, and Ford, produced between 2015 and 2020. The transmission range sensor is crucial as it informs the engine control module (ECM) about the selected gear position. When this sensor fails or provides incorrect data, it can lead to significant driving issues. Real-world implications of a P0983 code may include erratic shifting, inability to shift into certain gears, or the check engine light illuminating. If left unaddressed, these issues can lead to further mechanical failures or damage to the transmission system. Vehicle owners might notice that the engine RPMs are higher than usual during shifts, or the vehicle may unexpectedly stall when changing gears. Regular maintenance of the transmission system and immediate attention to warning codes like P0983 can prevent costly repairs down the line.
System: P - Powertrain (Engine, Transmission, Emissions)
Symptoms
Common symptoms when P0983 is present:
- Check engine light stays on constantly, indicating a problem with the transmission range sensor.
- Engine hesitates during acceleration, leading to a frustrating driving experience as the vehicle may not respond as expected.
- Fuel economy decreased by 10-15%, often due to the engine working harder to compensate for incorrect gear shifts.
- Unexpected stalling when shifting gears, which can pose serious safety risks while driving.
- Difficulty shifting into reverse or other gears, making it challenging to operate the vehicle smoothly.
Possible Causes
Most common causes of P0983 (ordered by frequency):
- The most common cause of a P0983 code is a faulty transmission range sensor, which has a likelihood of around 60%. This sensor may wear out or suffer from electrical issues.
- Another common cause is damaged wiring or corroded connectors in the sensor circuit. This can lead to intermittent signals or complete failure of the sensor.
- Improper transmission fluid levels or quality can also trigger a P0983 code. Regular checks and maintenance of your vehicle's transmission fluid can help prevent this.
- Less common but serious causes include internal transmission failures, which can be costly to repair. These might stem from neglecting regular maintenance.
- A rare cause could be a malfunctioning ECM, which may misinterpret signals from the transmission range sensor, leading to erroneous readings.
