They take the camshaft position actuator solenoid right out of the box and slide it into position. Please follow this diagnostic or repair process thoroughly and complete each step. Difference between Camshaft Sensors and Solenoids As you can see the camshaft position sensor simply reports to the computer the current position of the camshaft. If there is no engine block damage present, disassemble the engine and inspect the following components for damage due to thrust bearing debris in the engine oil: all bearings, all journals, all valvetrain components, all timing components, and the crankshaft Then, estimate what it will cost to replace the oil pump, camshaft actuator solenoid, all damaged parts, and to completely disassemble the engine to thoroughly clean all of the cylinder head and engine block oil galleys with oil galley brushes and soapy water. Com Has this vehicle ever had a cylinderhead replacement or cam phaser replacement? Replacing the camshaft position sensor on a trailblazer is an easy operation. Below in the diagnosis and repair tips section we'll talk about what it takes to remove the camshaft position actuator so you can verify the holes are plugged with sludge.
In fact the two most common codes associated with the camshaft position sensor failure remain the P0340. This guide, while I didn't do the cleaning part of it, certainly helped me build the confidence to go through with this project. I have this trailblazer and I keep getting a return code of p1345 and sometimes a p0014 now ive re placed the cam positioning sensor and the crankshaft sensor cam acuator solenoid the p1345 keeps coming back and I wondering if you herd this before. Once confirmed and repaired I replace the cam position sensor just as a good measure. Didn't see a response from the question by Crown396.
Each time it cut off she was at a standstill traffic light, parked, making a u turn, etc. You will see a black cover with a connector right behind the serpentine belt about in the middle of the engine. Replaced idler pulley and oil change by pep boys. First, you replace the black top exhaust position valve and when that's completed and reconnected move on to the intake side. Note that on the intake side that this lock tab is a different color and easy to see. Installation is pretty snug, by the way.
Too many times I replaced either the camshaft sensor and or the solenoid and the other part soon failed after the fact. You'll find this issue surfacing on Trailblazer models from 2002 through 2006. The actual actuator or cam phaser is a part on the end of the exhaust camshaft, directly connected to it and thus the gears and timing chain for the purpose of working the angles. . In this situation we might set a misfire code in the P0300 range.
Thankfully, the prices continue to come down on the replacement parts. Repair Procedure for Cam Actuator Valve Replacement I've watched a few videos of other people replacing these camshaft position actuator solenoid valves. This all aluminum fuel injected engine is a dual overhead cam design. Some folks have had issues with the after market versions of this part. Is it really a concern? We've seen an increased failure rate of the variable valve timing actuator solenoid. The actuator is part of the exhaust cam timing gear and the front timing upper cover will have to come off. The lubrication makes the O-ring more resistance to nicking as it slides into place.
If you have questions about this part or its installation go over to 355nation. Car makers use the cam position actuator solenoid valve to adjust the engine timing on the fly. And there's a couple of quick checks we can make at the camshaft position actuator. You can find information about the 6 cylinder here. The cam phasing system is a hydraulically actuated phase shifting mechanism. If by chance the replacement of the tensioner and belt was for belt noise, this could be an indication of excessive crankshaft end play, as the belt would not be aligned with the other pulleys since the crankshaft has walked forward.
One just reports on the position and the other one physically provides movement of the cam phaser. The valve body is an extremely complicated part that helps the fluid build pressure to help in shifting. Although I'm a firm believer in only replacing failed components in this situation I had to adjust my thinking for the sake of my customers. I'm a big believer in testing parts before replacing them. You can also find a code P1345 which stands for a camshaft correlation error. Some people dream of things that never were and ask, Why not? If you thought you had to do a lot of work to get this far, just wait until you start pulling the front cover off and find out you have to remove the oil pan. This prevents additional downtime of the vehicle.
Remember, they make the threads from a soft aluminum material. Someone that has done it multiple times. I need to change it more often with just regular Full Synthetic and not Extended Performance 15k mile oil. Using power tools can easily strip or pull these threads out and again lengthening the repair time. Was a little gummy and difficult to clean the Ring of Crap that built-up next to the Butterfly Helped with Idling Issues. Then start the car up and let it run on idle for about 5-10min with everything on. Trailblazer Camshaft Position Actuator I wanted to cover the Trailblazer camshaft position actuator problem first.
