P3460 - OBD Trouble Code

<<See All OBD Codes

See the error code P3460 flashing? Well, don’t worry! Parts Avatar is here to help you. Here we have listed all that you need to know about the error code P3460. This OBD-II code decreased engine performance is also described as a cylinder 8 deactivation/intake valve control circuit high. A number of manufacturers are making use of the cylinder deactivation systems for meeting the fuel and emission standards. Further, it should be noted that this system enables the engine control module (ECM) to stop selected cylinders at the time when additional power isn’t required from the engine (such as idle or cruising while on a highway). The PCM sets the error code P3460 when if the engine control module determines that the intake valve for cylinder number eight is not turning on or off the way as per the requirements.

For improving the fuel economy during light load operations (such as highway driving) the cylinder 8 deactivation/intake valve control circuit serves the purpose of accommodating the cylinder deactivation feature (e.g. V4 mode of a V8 engine). By the engagement of the intake deactivating solenoids for four of the engine cylinders, the engine control module (ECM) monitors the 4- or 8-cylinder modes of the engine. Also, this code sticks to the number 8 cylinder while the other three cylinders in this process are given by the engine configuration and the firing order of the cylinders. You can locate the number one-cylinder deactivation solenoid on or near the intake in the proximity of that cylinder based of the specific vehicle and the configuration.

What causes this problem with the Cylinder 8 Deactivation/Intake Valve Control Circuit High?

• Less oil pressures
• Blocked oil passage
• Engine mechanical status
• Damaged cylinder deactivation solenoid
• Open or short-circuited cylinder deactivation solenoid harness
• Bad electrical connection in the cylinder deactivation solenoid

1. Engine Control Module - Malfunctioning ECMs can often be problematic. In order to sustain the overall operations of the system an excellent quality ECM is essential. So, to add some spark to your ride you definitely need the perfect quality ECMs offered at Parts Avatar. Isn’t that just the perfect deal?
2. Powertrain Control Module - Dreaming to travel? But see a no-start condition? Sluggish engine cranks? Well, all these problems are likely to be caused due to malfunctioning powertrain control module. Repair or replace now from Parts Avatar.
3. Intake Valve - Don’t know what all a defective intake valve can do? Coolant problems are caused due to a fault in the intake valve. Not only this, a low acceleration and decrease in power can be seen too. Tune into Parts Avatar for your new intake valve. Order now!
4. Exhaust Valve - A lot of issues can arise due to a faulty exhaust valve. So, in order to fix your error code P3460, it is essential to fix your error code P3460 now. Log in to Parts Avatar for your new exhaust valve.
5. Engine Oil Pressure Gauge - Oil pressure light blinking? Alarmed? Well, we advise you to fix your oil pressure gauge immediately. Visit us today!
6. Variable Camshaft Timing Solenoid - Observing a dirty engine oil? Decreased fuel efficiency? Then this is indicative of a fault in the valve timing solenoid. Log into Parts Avatar now for getting your hands on your new valve timing solenoid.

It is essential to know the symptoms of an issue as only then you would be able to solve the problem. So that’s why we have listed out some major symptoms of OBD code P3460 here:

Here are some steps which you should follow in order to diagnose this fault code:

Firstly, in the troubleshooting process for any error, you should look for the technical service bulletins (TSB's) for the specific vehicle by year, model and engine. At times, this proves to be extremely helpful in narrowing down the possible causes. Next, the condition of the engine oil should be checked. Also make sure that it is serviced as per the needs. Find all the parts linked to the cylinder 8 deactivation intake valve control circuit and look for traces of physical damage.

According to the specific vehicle, this circuit has several parts installed that include the deactivation solenoid, switches, fault indicators and the engine control module. Then, a thorough visual inspection should be performed to check the linked wiring for errors like as scraping, rubbing, open wires or burn spots. Then proceed to check the connectors and connections for security, burns and defective pins. This inspection should include all the wiring connectors and connections to all the parts including the engine control module. We advise you to follow the specific tech data for the vehicle for confirming the configuration of the cylinder 8 deactivation/intake valve control circuit. Also, make sure that all parts are fit within the circuit (including a fuse or a fuse-able link).

Advanced steps that should be followed:

These steps are extremely vehicle specific and should only be performed using the correct advanced equipment. A digital multimeter and the specific technical references for the vehicle are required for performing these procedures.

Voltage checks that should be performed:

It should be noted that the reference voltage and its acceptable ranges vary according to the specific vehicle and the circuit configuration. For an accurate diagnosis, specific technical data should include troubleshooting charts and the appropriate sequence. By performing this process, you may identify the absence of a power source or ground. Continuity testing should be performed to check the integrity of the wiring, connectors and other parts. Note that these continuity tests should always be performed with the power disconnected from the circuit and the normal readings for wiring and connections should be 0 ohms of resistance. If you find resistance or no continuity, then this is indicative of a malfunction or corrosion in the wiring.

Common mistakes when diagnosing the P3460 code

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

• Low engine oil level
• Failed powertrain control module (PCM)
• Faulty variable valve timing solenoid
• Wiring issues in the system
