This code means that the car's computer found a problem with the part that helps control how much air goes into the engine. It's like when a door doesn't open or close properly.
The throttle valve actuator is responsible for controlling the air intake in the engine. This code indicates a failure in the actuator's ability to perform its self-test and return to a safe position.
The P1694 code is triggered when the Engine Control Module (ECM) detects that the throttle valve actuator cannot perform its start test, spring test, or return to the limp home position. This can affect the engine's ability to manage air intake effectively, leading to performance issues.
• Check Engine Light is on
• Reduced engine performance
• Vehicle may enter 'limp' mode
• Faulty throttle valve actuator
• Wiring issues or poor connections
• Faulty ECM
Throttle Valve Actuator: A component that controls the air intake into the engine.
Limp Home Mode: A safety feature that limits engine power to allow the vehicle to be driven to a service location.
• Use an OBD-II scanner to confirm the code.
• Inspect the throttle valve actuator for damage or wear.
• Check wiring and connections to the throttle actuator.
• Replace the throttle valve actuator if faulty.
• Repair or replace damaged wiring or connectors.
• Reprogram or replace the ECM if necessary.
• OBD-II scanner
• Multimeter
• Screwdriver set

Moderate
• Volkswagen Passat
• Audi A4
• BMW 3 Series
• Regular maintenance and inspection of the throttle system.
• Ensure proper electrical connections.
• Keep the throttle body clean.
Engine Performance
• Avoid driving at high speeds until the issue is fixed.
• Seek professional diagnosis to avoid further damage.
Check with your vehicle manufacturer for warranty coverage on the throttle system.
This code has been associated with vehicles that have electronic throttle control systems, which became more common in the 2000s.
Moderate – It is important to address this issue to prevent further engine performance problems.
Driving with this code may lead to reduced engine performance and could be unsafe. Address the issue promptly.
• Engine running
• Throttle actuator self-test initiated
The throttle valve actuator is typically located on the intake manifold or throttle body of the engine.
Q: Can I drive my car with a P1694 code?
A: It's not recommended, as the car may have reduced performance and could be unsafe.
Q: How can I prevent this code from appearing?
A: Regular maintenance and ensuring the throttle body is clean can help prevent this issue.
