When the P0344 code is stored, it indicates that the signal from the camshaft position sensor has been interrupted. This sensor measures the rotational position of the camshaft as it relates to the crankshaft. Data from the camshaft position sensor is used to control fuel injector timing and ignition spark.
What causes P0344?
Causes of the P0344 Code
Defective camshaft position sensor. Electrical short or damaged wiring. Malfunctioning camshaft position sensor tone ring. PCM issues, either defective or lack of updates.
What does P0344 mean?
Diagnostic trouble code (DTC) P0344 stands for “Camshaft Position Sensor “A” Circuit Intermittent (Bank 1 or Single Sensor).” It triggers when the PCM detects a loss of signal from the Bank 1 camshaft position sensor. Bank 1 refers to the bank of the engine that contains cylinder #1.
Where is the camshaft position sensor located?
The Camshaft Position sensor is typically located in the cylinder head of the engine and has a cylindrical portion that inserts into the head. The Crankshaft Position sensor is normally located in the timing cover or on the side of the block with a cylindrical portion that inserts into the block.
What is the camshaft position sensor bank 2?
The CMP sensor measures the exact rotational position and speed and position of the camshaft. The data that the CMP gathers is important because it’s used by the ECM to control the ignition spark and the fuel injector timing.
How do you fix P0344?
What repairs can fix the P0344 code?
- Replacing a weak or dead battery.
- Replacing chafed, melted, or otherwise damaged wiring.
- Cleaning electrical connections to the camshaft position sensor.
- Replacing the camshaft position sensor.
- Replacing the crankshaft position sensor.
How do you fix a camshaft position sensor?
Zitat von Youtube: If it has repair the leak to prevent the new sensor from being damaged. Check to make sure the o-ring from the sensor hasn't fallen into its hole push. The new sensor into place and replace the bolt.
How much does it cost to replace a camshaft position sensor?
The average cost for camshaft position sensor replacement is between $176 and $227. Labor costs are estimated between $72 and $90 while parts are priced between $105 and $136. This range does not include taxes and fees, and does not factor in your specific vehicle or unique location. Related repairs may also be needed.
What causes a camshaft position sensor code?
The most common causes behind the disruption of the signal from the camshaft position sensor to the PCM include: Failing or defective camshaft position sensor. Circuit problems (e.g., damaged wiring, loose connections) Errors in the powertrain control module (somewhat rare)
What does a cam sensor do when it goes out?
A failing camshaft position sensor begins losing its ability to quickly transfer data. Mismatched fuel delivery and ignition timing, even if off by a few milliseconds, will cause your vehicle to sputter, accelerate poorly, lack power, stall or even shut off.
How do I reset my camshaft sensor?
Zitat von Youtube: Back on the scanner screen select crank pattern. Clear select continue once crank pattern clear is complete select crank pattern. Learning select continue the relearn is complete.
How long does it take to replace a camshaft sensor?
between one and two hours
Replacing a camshaft position sensor typically takes between one and two hours. However, this may vary depending on the make and model of your vehicle.
