P3464 - OBD Trouble Code

<<See All OBD Codes

Only for our customers we have mentioned here all that you should know about the error code P3464. This OBD-II code decreased engine performance is determined as a cylinder 8 exhaust valve control circuit high. A number of manufacturers’ employ cylinder deactivation systems attaining the fuel and emission standards. When additional power isn’t required from the engine, this system allows the engine control module (ECM) to disable select cylinders at times when the engine is at idle or when cruising on highway. The PCM sets the code P3464 when if the engine control module dictates that the exhaust valve for cylinder number eight is not turning on or off as per the commandments.

The cylinder 8 exhaust valve control circuit performs the function of turning off the exhaust valve in order to accommodate the cylinder deactivation feature (e.g. V4 mode of a V8 engine) for enhancing the fuel economy during light load operation at idle or on the highway. For the deactivation of four of the engine cylinders, the engine control module (ECM) regulates the 4- or 8-cylinder modes. You should note that this procedure is completed by incorporating variable valve timing solenoids that further turn the exhaust valves on and off as per the requirements.

This code P3464 is mainly concerned to the number 8 cylinder while the other three cylinders in this procedure are determined by the engine configuration and the firing order of the cylinders. Firstly, the ECM restricts the cylinder deactivation to a cycle time of 10 minutes in V4 mode and then finally returns to the V8 mode for 1 minute. According to the specific configuration and the vehicle, the number 8-cylinder variable valve timing solenoid can be found on or near the exhaust manifold in the surrounding of that cylinder.

What causes this problem with the Cylinder 8 Exhaust Valve Control Circuit High?

• Malfunctioning variable valve timing solenoid
• Less engine oil level or pressure
• Blockage in the oil passage
• Corroded or damaged wiring
• Open or defective connector
• Damaged ECM

We at Parts Avatar Canada care for our customers, and that’s why we will help you to diagnose P3464 code by listing out some major symptoms. They are mentioned below as follows

Common Symptoms

• You may notice an increase in the fuel consumption
• Falling engine performance
• The driver will see engine misfires
• An illuminated service engine soon light or/and check engine light

Learn the ways with which you can correct this trouble code:

• Replace or repair a defective variable valve timing solenoid
• A careful cleaning or the corrosion should be performed in the connectors
• Make sure you repair or replace a faulty wiring
• All the jammed oil passages should be cleaned and cleared
• Mend or restore a defective ECM

Don’t get tensed if you are still facing any of these issues as we care for our customers and that’s why we offer a good range of PCM, ECM, exhaust valve, exhaust valve control solenoid, timing chain, camshaft actuator, valve lifter, timing component and a lot more. We are sure that now all your issues would be resolved.

It is essential to diagnose this fault code. Here are some steps which a mechanic should follow for diagnosing the problem that triggered a P3464 code to be stored:

First and foremost in the troubleshooting process for any defect, you should find the technical service bulletins (TSB's) for the specific vehicle by year, model and engine. A lot of times, this proves to be extremely fruitful as it helps pointing out the right direction. Secondly, check the condition of the engine oil and make sure that it is serviced to the required level. Then proceed forward to find components associated with the cylinder 8 deactivation intake valve control circuit to check for signs of physical damage. This circuit usually incorporates many components that consists of the deactivation solenoid, switches, fault indicators and the ECM based on the specific vehicle. A thorough visual inspection should then be performed to check the associated wiring for problems such as scraping, rubbing, loose wires, or corrosion spots. Inspect the connectors and connections for security, corrosion and defective pins. This procedure performed should include all the wiring connectors and circuitry to all components (including the ECM). We advise you to refer to the specific tech data for the vehicle to verifying the configuration of the cylinder 8 deactivation/intake valve control circuit. Make sure that every component incorporated within the circuit should include a fuse or a fuse-able link.

Advanced steps that should be performed:

Well, the advanced steps focus on particular vehicles and require the appropriate advanced equipment for accuracy. A digital multimeter and the specific technical references for the vehicle should be employed.

Voltage checks that should be performed:

These reference voltage and the adequate ranges change based on the specific vehicle and the circuit configuration. Generally, the specific technical data includes troubleshooting charts and the appropriate order to follow for a precise diagnosis. If in case, this procedure registers the lack of a power source or ground, you may be required to perform a continuity testing to check the integrity of the wiring, connectors and other components. These continuity tests should always be performed with the following: power removed from the circuit and the normal readings for wiring and connections should be 0 ohms of resistance. Also, resistance or no continuity is symbolic of a malfunction in the wiring that is loose or shorted. It must be repaired or replaced.

Common Mistakes When Diagnosing the P3464 Code

Here we have listed a few common mistakes that should be avoided:

• Extremely low engine oil levels
• Failed powertrain control module (PCM)
• Malfunctioning variable valve timing solenoid
• Corroded or faulty wiring
