Common Symptoms of a Faulty Gear Shift Position Sensor
A malfunctioning gear shift position sensor in a 2013 Dodge Dart can lead to various operational issues that affect both drivability and safety. Recognizing these symptoms early can help prevent further damage and ensure proper vehicle function.
One of the most noticeable signs is erratic or inaccurate gear indicator readings on the dashboard. The sensor informs the vehicle’s computer of the current gear selection, so any inconsistency in this communication can cause confusion in gear display.
Other symptoms include:
- Difficulty shifting gears or the transmission not engaging properly
- The vehicle starting only in neutral or park, or failing to start altogether
- Activation of the check engine light or transmission warning light
- Unexpected or harsh shifting behavior during driving
- Inability to shift out of park, potentially leading to the vehicle being immobilized
In some cases, the engine control module (ECM) or transmission control module (TCM) may trigger diagnostic trouble codes (DTCs) related to the gear shift position sensor, which can be retrieved using an OBD-II scanner.
Diagnostic Procedures for Gear Shift Position Sensor Issues
Diagnosing a faulty gear shift position sensor involves a systematic approach to isolate the sensor from other potential causes of transmission problems. The following steps outline the typical diagnostic process used by professionals:
- Visual Inspection: Check the sensor and its wiring harness for signs of damage, corrosion, or loose connections. Any physical damage can cause signal disruption.
- Scan for Trouble Codes: Use a diagnostic scanner to read any stored DTCs related to transmission or sensor malfunctions, such as P0705 (Transmission Range Sensor Circuit Malfunction).
- Sensor Signal Testing: Using a multimeter or oscilloscope, measure the sensor’s voltage output and resistance to verify if it aligns with manufacturer specifications.
- Functional Testing: Shift through all gear positions while monitoring sensor output to confirm accurate gear indication.
- Connector and Wiring Checks: Test continuity and resistance in the sensor’s wiring to ensure no short circuits or open wires exist.
If the sensor fails any of these tests, replacement is typically required.
