The Camshaft Position Actuator Solenoid Trouble Code Does Not Go Away The most common failure you'll encounter with the camshaft position actuator solenoid is that its internal spool valve does not move anymore. While in the United States they are unable to receive Turn-by-Turn directions. Typically, this is the result of a camshaft actuator solenoid concern. The exact same camshaft position actuator solenoid is used on the 2002 through 2009 4. When the exhaust camshaft is retarded at the maximum rate, the duty cycle of the signal is at 100 percent. Without power the camshaft position actuator solenoid will not work.
If the spool valve moves when applying battery power and Ground then you can conclude that the solenoid is working correctly. The code definition of the P0340 states that it sets when the camshaft position sensor, bank one, shows a circuit malfunction. Technician can check Service Information for some accessories. Either because it has streteched or one of its tensioners is worn out. Technician will find that the OnStar led is red and Diagnostic Trouble Code U1500 is set. The maximum advance rate has a 0 percent duty cycle.
Use the appropriate tool to connect your multimeter test lead to the terminal or wire. If the crankshaft end play is obviously out of specification, inspect the engine block for damage due to contact with the crankshaft. Technician can check Service Information for some accessories. Any use of such information is at the user's sole risk, and in no event shall the provider be liable for any consequential, incidental, special, punitive or direct or indirect damages arising from such use. Although I believe replacing one part for one problem I have seen enough failures of both of these components to falter from my beliefs.
In this situation we might set a misfire code in the P0300 range. The cool thing about testing the camshaft position actuator solenoid is that you don't need any expensive tools to do it. They actuator or solenoid physically advances and retards the timing as required. In fact the two most common codes associated with the camshaft position sensor failure remain the P0340. This is why mechanics believe in starting diagnosis with the lowest number code first. Interesting enough, I have come across the P0014 camshaft position actuator timing over advanced code more often than the other possible codes that could set in that range.
For more suggestions on troubleshooting the camshaft position actuator trouble code see:. Here's a quick video of. Technician may also find a Diagnostic Trouble Code P0521 in the Engine Control Module. In other words, the computer has given the command for the solenoid to activate and not detected that the solenoid followed the instructions. Technician may find Diagnostic Trouble Code P0442. If all these screens are present, measure the crankshaft end play to determine if it is within the specification of 0. Technician will gain access to the roller rockers to inspect them.
You'll find this issue surfacing on Trailblazer models from 2002 through 2006. This is especially true on high mileage engines and trucks with questionable history. Please follow this diagnostic or repair process thoroughly and complete each step. Symptoms Of A Defective Camshaft Position Actuator Solenoid The camshaft position actuator solenoid is tasked with the job of rotating the exhaust side camshaft relative to its sprocket to advance or retard its timing. If this is due to a worn crankshaft thrust bearing, some customers may also comment on a drive belt noise.
In order to remove the camshaft timing solenoid you must take loose the power steering pump from its mounting bracket. If your test results indicate the solenoid is defective, take a look at the following links. Typically, if excessive crankshaft end play is causing this concern, it will be obviously out of specification by. If the signal flat lines for long enough, the engine stalls out. Since both of these components remain relatively inexpensive, I'm now recommending to my customers that they replace both parts at the same time. What Tools Do I Need To Test The Camshaft Position Actuator Solenoid? See the 4 cylinder engine with.
When the exhaust camshaft is retarded at the maximum rate, the duty cycle of the signal is at 100 percent. If the spool valve does not move move when you apply power and Ground to the solenoid then you can conclude that the solenoid is defective and needs to be replaced. These two components work together to control the variable valve timing system. The end result is variable valve timing that improves engine performance, fuel economy and a reduction in emissions. In this tutorial I'm going to be showing you how to test the camshaft position actuator solenoid. If this is due to a worn crankshaft thrust bearing, some customers may also comment on a drive belt noise.
