Is P0449 a Serious Concern? This concern may be due to debris in the camshaft actuator system, which may be caused by a missing camshaft actuator solenoid screen or a worn crankshaft thrust bearing. If a boroscope is not available, removal of the oil pan will be required.

Now you did not say which engine you have in the TrailBlazer. My car has an automatic transmission. Car is still running fine though. The list of automotive Makes at the right edge of the screen. Then, check that the 5-volt reference is getting to the sensor by connecting the red multimeter lead to the reference voltage pin and the other to ground.
This gasket can dry out, especially with vehicles that spend their time in dry climates. The pulse from the 10 degree slot is known as the sync pulse. Testing a Hall Effect Sensor Courtesy: autorepairhelp. Timing belts can stretch over time and mileage, and are flexible enough to skip time. I'm currently dealing with Camvap for my 2013 wrangler with 65,000km that Chrysler doesn't want to honor the warranty for.
Is P0301 a Serious Concern? Hooking up a scope to a Hall Effect sensor Courtesy: autozone If the synchronization pattern is distorted, you need to find out why. . All Rights Reserved Posted on Aug 26, 2011 Its a cam over-retarded code. Typically, this is the result of a camshaft actuator solenoid concern. The magnetic field of the sensor is altered by a crankshaft mounted reluctor wheel that has seven machined slots, 6 of which are equally spaced 60 degrees apart. P0449 Diagnosis- Chevy Trailblazer A mechanic has a wide range of instruments at his or her disposal to diagnose what would be causing the P0449 in your Chevy Trailblazer.
