What is an OBD2 code?

An OBD2 (On-Board Diagnostics) code is a diagnostic trouble code (DTC) generated by your vehicle's computer system when it detects a problem. These codes help identify specific issues with your vehicle's engine, transmission, emissions, or other systems.

How do I read OBD2 codes?

To read OBD2 codes, you'll need an OBD2 scanner. Plug it into your vehicle's OBD2 port (usually located under the dashboard), turn your key to the 'ON' position, and follow your scanner's instructions to retrieve the codes. Each code starts with a letter (P, B, C, or U) followed by four numbers.

What do the different types of OBD2 codes mean?

OBD2 codes are categorized by their first letter: P (Powertrain) for engine and transmission issues, B (Body) for interior systems like airbags, C (Chassis) for mechanical systems like brakes, and U (Network) for computer and module communication problems.

Code P0762

Symptoms

• Transmission stuck in one gear

• Harsh or delayed shifting

• Transmission slipping

Common Causes

• Faulty shift solenoid C

Official description

Shift Solenoid C Stuck On

Laymans terms

Your car's computer thinks a part that helps change gears is stuck and won't turn off.

Explanation

The P0762 code indicates that the transmission control module (TCM) has detected that the shift solenoid C is stuck in the 'on' position, preventing proper gear changes.

Technical description

Shift solenoids are responsible for controlling fluid flow to the transmission's hydraulic circuits, which engage different gears. The 'C' solenoid being stuck 'on' means it is continuously allowing fluid flow to a specific gear, which can cause improper shifting or being stuck in one gear.

Diagnosis steps

• Check transmission fluid level and condition

• Inspect wiring and connectors to the shift solenoid

• Test the shift solenoid C for proper operation

Repair procedures

• Replace the shift solenoid C

• Repair or replace damaged wiring or connectors

• Perform a transmission fluid flush and refill

Tools required

• OBD-II scanner

• Multimeter

• Transmission fluid pump

Estimated repair cost

$200 - $500
