The P3475 code is the universal OBD-II code for Cylinder 10 Deactivation/Intake Valve Ctrl Circuit Low. Cylinder 10 indicates a malfunction in engine cylinder number 10. Related codes in the P3400 series may also set with this code.
Some engines have the ability to shut down certain cylinders under operating conditions which don’t require full engine power. This is achieved by way of the valves opening and closing at precise times, either activating or deactivating.
The MAF (mass airflow) sensor, MAP (manifold absolute pressure) sensor, and TP (throttle pressure) sensor work together to control when the intake valve opens and closes. These sensors send signals to the ECM (engine control module), which are translated into voltage. When the ECM receives a signal from the sensors which falls outside the range of normal, the P3475 code will set, alerting you to a malfunction somewhere along the circuit which controls the cylinder 10 deactivation/intake valve.
Any of the following could potentially cause this code to set:
In addition to setting the fault code, the vehicle will be unable to run in lower modes, and there may be vibrations while driving. The Check Engine Light may illuminate, and fuel efficiency will be affected.
The steps that a technician will take to pinpoint this code may include:
One of the most common errors when diagnosing this code is neglecting to check the oil passageways for clogged areas. This is a simple, inexpensive fix which – if found to be the source of the problem – can save the owner money and hassle replacing parts that are not broken.
Another problem is when the manufacturer’s recommended protocol for pinpointing the issue is not followed. Each step should be carried out in order to prevent missing a crucial clue to the source of the issue.
In addition to setting the trouble code, the Check Engine Light will illuminate and there may be engine vibration while driving. The vehicle will not operate in lower engine modes, and fuel economy will suffer over time.
Repairing a cylinder 10 deactivation/intake valve malfunction may involve the following:
Larger engines are more complex, and identifying the source of a deactivation/intake valve problem could involve a lengthy process for which most driveway mechanics are not prepared. Particularly if the engine needs to be completely disassembled in order to thoroughly clean out the oil passageways, the job can be time-consuming and require special tools that a qualified mechanic will have on hand.
Letting a pro handle this type of code can save you time, hassle, and money.
