P0824 code definition
The P0824 code is a generic powertrain code related the transmission, including pressure faults and sensor failures. In this case, the engine control module (ECM) has detected a fault in the transmission shift mechanism range for the Y gear lever position.
Codes related to the P0824 include:
- P0820: Gear Lever X-Y Position Sensor Circuit
- P0821: Gear Lever X Position Circuit
- P0822: Gear Lever Y Position Circuit
- P0823: Gear Lever X Position Circuit Intermittent
- P0825: Gear Lever Push-Pull Switch (Shift Anticipate)
What the P0824 code means
A P0824 code will only apply to vehicles with an automatic transmission. The automatic transmission range/speed sensor sends data to the ECM, which uses the data to calculate fuel delivery strategy, the engine’s RPM, engine timing, and more. Transmission range sensors are frequently variable resistance, and the switch is often positioned over the transmission shift shaft. The shift lever slides over the shift shaft. When the lever is moved, it pivots the range sensor to different contact points.
If the sensors including the vehicle speed sensor, transmission shift solenoids, or torque converter lock-up solenoid show that the vehicle is not in the correct transmission shifter range, a P0824 code is stored.
What causes the P0824 code?
Several problems may cause a P0824 code including:
- Incorrectly adjusted transmission range sensor
- Defective or damaged transmission range sensor
- Damaged, corroded or faulty wiring and other circuit componentry
- Possible corrosion in sensor connector
What are symptoms of the P0824 code?
Symptoms of a P0824 code may include:
- A check engine or warning light may illuminate
- The vehicle may shift harshly
- The vehicle may not shift at all
- Decreased fuel economy
How does a mechanic diagnose the P0824 code?
A mechanic may use several methods to diagnose a P0824 trouble code, including:
- Utilize an OBD-II scanner to check for a stored P0824 trouble code
- Visually inspect the wiring and componentry related to the gear lever and transmission range sensor
- Check adjustment of transmission range sensor
- Check transmission range sensor for battery voltage as well as ground signals
- Use a digital volt/ohmmeter to test for continuity and resistance if voltage or ground signals were open
- Test all related circuits and componentry for resistance and continuity
Common mistakes when diagnosing the P0824 code
The most commonly reported cause of a P0824 is due to an incorrectly adjusted transmission range sensor. Before replacing sensors, it is recommended to check that they are adjusted to manufacturer specifications.
How serious is the P0824 code?
Because a vehicle’s safe driving operation may be impacted due to faults that store a P2090 code, including the inability to shift, this code is considered a potentially serious code. When this code appears, it is recommended to immediately take your vehicle to your local service center or mechanic for repair and diagnosis.
What repairs can fix the P0824 code?
Several repairs can fix a P0824 trouble code and include:
- Repair or replace any damaged, shorted, or corroded wiring and related componentry
- Repair or replace damaged circuits and connectors
- Adjust transmission control sensor to manufacturer recommended levels
- Repair or replace damaged or defective transmission control sensor
- Clear all codes, test-drive the vehicle, and rescan to see if any codes reappear
Additional comments for consideration regarding the P0824 code
Transmission sensor related codes often accompany other shift solenoid codes. It is recommended to diagnose all trouble codes in the order they appear as some may be symptoms of a larger problem.
