Definition: Camshaft Position Sensor 'A' Circuit Range/Performance (Bank 2)
Most technical data is theoretical. Manufacturers release service bulletins that describe how a system should work. However, a "verified" entry—specifically Autodata 346 Verified—means that the information has undergone an additional layer of real-world testing.
When Autodata appends "Verified" to a module (especially 346), it signifies that the data has been: autodata 346 verified
In the context of "346 Verified," this is crucial. VVT systems are notoriously sensitive. A generic guide might tell you to replace a camshaft actuator, but a verified guide will tell you the specific oil viscosity and pressure thresholds required for that actuator to lock properly. Without verified data, you are gambling with engine internals.
Replacing a VVT solenoid is easy. Relearning the camshaft position is not. AUTODATA 346 Verified includes proprietary relearn drive cycles that work. It tells you the exact engine load percentage, road speed, and deceleration time required to force the ECU to accept the new part. Without this "verified" drive cycle, your "check engine" light will often return within 50 miles. In the context of "346 Verified," this is crucial
If you ask a mechanic why they keep a copy of 3.46 handy, they will likely point to three key features:
1. Wiring Diagrams You Can Actually Read Modern diagnostic software often presents wiring diagrams as complex, hard-to-navigate digital flows. Autodata 3.46 became famous for its clear, concise, and standardized wiring diagrams. They are printable, easy to trace, and essential for tracking down parasitic drains or short circuits. In the context of "346 Verified
2. Timing Belt and Chain Data One of the most high-stakes jobs in a garage is a timing belt replacement. Get the tension or the locking point wrong, and you destroy the engine. Autodata 3.46 provides straightforward, step-by-step guides for timing procedures, including torque specs and locking pin locations, for thousands of engines. It is often the first place a technician looks before turning a single bolt.
3. Service Resets and Adjustments Before every service function was locked behind a manufacturer paywall or required an internet connection, Autodata provided the manual procedures for resetting service lights, adjusting handbrakes, and bleeding ABS systems. For older vehicles, this data is still 100% accurate and invaluable.
