What the P3467 code means
The P3467 code indicates that your vehicle’s intake valve control circuit is low.
What causes the P3467 code?
There may be one or more causes for the P3467 code. One may be that your circuit is not performing at the level it should. Another cause might be that something is shorted in the circuit. It could also be due to a poor electrical connection. You will need to investigate the problem carefully in order to determine just what the particular cause is. Run through tests on your own time, or take your vehicle to a professional technician.
What are the symptoms of the P3467 code?
Symptoms for the P3467 code include an illuminated Check Engine Light. In some instances, the engine may be difficult start or you may get poor fuel economy. Take your car to a technician immediately if you notice poor engine performance.
How does a mechanic diagnose the P3467 code?
A professional technician will use an OBD-II scanner and a digital volt/ohmmeter to perform a diagnosis.
They may also begin with a visual inspection of your connectors and wiring. Make sure that you replace or repair any damaged, shorted, disconnected, or corroded wiring, connectors, and other components. After the repairs are complete, make sure to retest the system to make sure that you were successful. If everything seems to be working adequately, connect your code reader or scanner to the diagnostic connector to record your vehicle’s freeze frame data and stored codes.
Be sure to check for unplugged harness connections and to look for corrosion or loose wires to connectors. Unplug harness connectors from the solenoid and your Powertrain Control Module (PCM), and then, using a wiring diagram, locate the + and - wires to the solenoid. With a digital volt ohm meter (DVOM) set to the ohms setting, check for resistance between each of the wires. With the electrical harness to the solenoid unplugged, use your DVOM to check for resistance on each of the electrical terminals on the control solenoid.
If you are getting a low resistance, the solenoid may be shorted internally. However, if all wiring and the control solenoid seem to work well, you will need to monitor the solenoid during engine operation by back probing the wires at the PCM/ECM. You will also need to monitor the solenoid during engine operation under various engine RPMs and load.
Common mistakes when diagnosing the P3467 code
The Manifold Absolute Pressure Sensor/Barometric Pressure Sensor is replaced when the real cause is a short to ground in your Map Sensor wiring. Other times, you might replace your Manifold Absolute Pressure Sensor when the real cause is an open circuit in the five-volt reference circuit.
How serious is the P3467 code?
The P3467 code is very serious and, unless you are very skilled and have the proper tools, should be examined by a professional technician. If you do not attend to this problem quickly, it may your affect engine performance and could reduce your gas mileage. It could also damage other components on your vehicle. It is always better to take your car to a technician as soon as you notice signs of change. Allowing a problem to go on for too long can have costly and at times irreversible effects on your vehicle.
What repairs can fix the P3467 code?
If you receive a P3467 code, you should check the engine oil level to make sure your oil capacity is sufficient. Dirty or contaminated fluid can lead to buildup, which can lead to a failure of your camshaft actuator or control solenoid.
Additional comments for consideration regarding the P3467 code
Many older vehicles have sensor problems that occur due to prolonged stress on the drivetrain. A P3467 can be very difficult to diagnose and repair. Your best bet may be to get your car into a technician who has the proper tools to diagnose your problem more efficiently and in less time.
