P0822 OBD-II Trouble Code: Gear Lever Y Position Circuit

diagnostic check engine light

P0822 code definition

The P0822 code indicates a problem with the transmission range sensor. The position that the gear lever is in does not correspond to the gear that the vehicle is operating in.

The P0822 code is often associated with the P0820 and P0821 trouble codes.

What the P0822 code means

P0822 is the OBD-II generic code for a problem with the range that an automatic transmission is operating within. The transmission range sensor is the sensor that relays critical information to the powertrain control module regarding what gear the transmission should be in to operate efficiently. To do this, the vehicle also relies on data from the vehicle speed sensor and torque converter solenoid.

If, for some reason, the data coming from the sensors indicates that the transmission is not operating in the correct gear, the P0822 code will be indicated.

What causes the P0822 code?

The incorrect transmission range code may be indicated via a number of causes:

What are the symptoms of the P0822 code?

Once the P0822 code is indicated, the Check Engine light will illuminate on the vehicle’s dashboard. The transmission may have trouble shifting up or down. When the transmission does shift between gears, the shifts may be rough and make the car feel like it is driving more harshly. These issues with the transmission may cause a drop in fuel economy.

How does a mechanic diagnose the P0822 code?

A qualified technician will first use a diagnostic scanner to read the OBD-II trouble codes from the engine in real-time. The mechanic can use this tool to see exactly when the code was first set and get an idea of what caused it to be indicated. The technician will then reset the codes and restart the engine. They will also take the vehicle for a test drive to see if and when the trouble code indicates again. There is a chance that a small electrical issue cause the code to be indicated, and that there is no permanent problem with the transmission.

If the code is indicated during the test, then the mechanic will first check the area around the shift lever and transmission range sensor for signs of damaged or corroded wiring that may be interfering with the signal getting to the powertrain control module.

Common mistakes when diagnosing the P0822 code

Often, when there is an issue with the transmission range sensor, the sensor is simply replaced. This can be wasteful, as most instances of the P0822 code can be solved by properly adjusting the transmission range sensor. Other times the code is indicated due to issues with surrounding parts and circuits.

How serious is the P0822 code?

The P0822 code will not stop the engine from starting and it cannot shut the engine down when it is running. In a worst-case scenario, the P0822 code will cause the automatic transmission to enter “limp mode” and severely reduce performance. Due to the fact that this code can severely impair proper vehicle operation, it is moderately serious and should be diagnosed as promptly as possible when it appears.

What repairs can fix the P0822 code?

The most common repairs to address the P0822 code are as follows * Repair or replace damaged or corroded wiring around the transmission and specifically around the transmission range sensor * Transmission range sensor replacement or adjustment * Repair or replace wiring in and around powertrain control module * Repair or replace electrical connections within gear lever mechanism

Additional comments for consideration regarding the P0822 code

The P0822 code only indicates a problem with the gear lever position in vehicles equipped with an automatic transmission. If the code only appears intermittently, the issue may be an electrical problem that will take more time to properly diagnose. No diagnosis can be made until a code is indicated after the previous codes were already cleared.
