P3476 - OBD Trouble Code

<<See All OBD Codes

The trouble code P3476 can be explained as Cylinder 10 Deactivation/Intake Valve Control Circuit High. There are a number of fuel and emissions standards, so in an effort to meet that lot of manufacturers are using the cylinder deactivation systems. This system would allow the engine control module (PCM) to disable select cylinders when additional power is not required from the engine, such as at idle or when cruising on the highway. Now if the engine control module (PCM) would decide that the intake valve for cylinder number ten is not turning on or off the way is being commanded, then the powertrain control module would set up this fault code.

If the engine control module would detect a variation in the voltage coming from the cylinder 10 deactivation/intake valve control circuit that is outside the parameters set by the automobile manufacturer, then it would store the P3476 error code. This would also give rise to the illumination of the check engine light.

What causes this problem with the Cylinder 10 Deactivation/Intake Valve Control Circuit High?

• Less oil pressures
• Cramped oil passage
• Malfunctioning engine mechanical condition
• Some issues related to the cylinder deactivation solenoid
• Unlocked cylinder deactivation solenoid harness
• Unsatisfactory electrical connection in the cylinder deactivation solenoid circuit

1. Engine Wiring Harness - The broken wires in the wiring harness might lead to some serious engine problems. So, make sure that you replace your faulty engine wiring harness to avoid such situation.
2. Engine Control Module - If there is any corrosion or breaks in the internal wiring of the harness, then it can cause a short in the ECM or can also cause corrosion in the ECM through the wiring harness. You can always rely on us as we have best auto parts for our customers.
3. Exhaust System Parts - Your exhaust system begins at the engine with the purpose of removing toxic gases and fumes from your vehicle. The components are a series of pipes, catalytic converters, sensors, mufflers, and often a resonator, as well as other emission devices. Thus, replace damaged exhaust system now!
4. Powertrain Control Module - The onboard computer, or powertrain control module is the brain of the engine control system. Now if the brain is not working properly, then neither is the car engine. Get it replaced before the situation gets worse.
5. Electronic Control Unit - Is your car jump starting on reverse polarity? Or are you facing some intermittent starting issues? If yes, then it indicates that your electronic control unit is bad. So, it is very important to replace the defective electronic control unit with us at equitable prices.

It is essential to diagnose this fault code. Here are some steps which a mechanic should follow for diagnosing the problem that triggered a P3476 code to be stored:

• Inspect for technical service bulletins which pertain to the vehicle, symptoms, and codes. In some circumstances this can save a lot of time in the long run by pointing you in the right direction.
• After that the next step is to inspect the condition of the engine oil and then confirm it is serviced to the appropriate level. After that all the components which are related with the Cylinder 10 Deactivation/Intake Valve Control Circuit should be located and then search for obvious physical damage.
• It all depends upon the particular vehicle and this circuit may incorporate several components including the deactivation solenoid, switches, fault indicators and the ECM. A proper visual inspection should be performed to inspect the related wiring for obvious defects such as scraping, rubbing, bare wires, or burn spots. Then examine the connectors and connections for security, corrosion and faulty pins.
• This process should include all wiring connectors and connections to all constituents including the engine control module. You can always consult the particular tech data for the automobile to check the configuration of the Cylinder 10 Deactivation/Intake Valve Control Circuit and confirm every component incorporated within the circuit which may include a fuse or a fuse-able link.
• Then make sure the fluid level is correct and inspect the condition of the fluid for contamination. After that perform visual inspection to check the associated wiring for obvious defects such as scraping, rubbing, bare wires, or burn spots should be performed.
• Next is to check the connectors and connections for security, corrosion and damaged pins. This process must include all wiring and connectors to the transmission solenoids, transmission pump and the PCM. It depends upon the configuration; the transmission linkage should be inspected for security and binding issues.
• The advanced steps become very vehicle specific and require the appropriate advanced equipment to perform accurately. These procedures require a digital multimeter and the specific technical references for the vehicle. Voltage requirements will vary based of the specific year and model of the vehicle. You should follow the specific troubleshooting chart for your vehicle.
• Continuity checks should always be performed with the power removed from the circuit and the normal readings for wiring and connections should be 0 ohms of resistance unless otherwise specified by the technical data. Resistance or no continuity is an indication of faulty wiring that is open or shorted and must be repaired or replaced.

Common Mistakes When Diagnosing The P3476 Code

• Malfunctioning powertrain control module
• There can be a failure in the variable valve timing solenoid
• The level of the engine oil might be less
• Wiring problems
