P3488 - OBD Trouble Code

OBD Code P3488 - Cylinder 11 Exhaust Valve Control Circuit High

<<See All OBD Codes

The trouble code P3488 can be described as Cylinder 11 Exhaust Valve Control Circuit High. This trouble code would indicate that there are some issues with the exhaust valve on cylinder number 11. The automobile’s control module would detect that the measured values from the TP sensor, MAP sensor, and MAF sensor are not within the range of the calculated values for cylinder deactivation mode.

Error code P3488 flashing. Keep on reading further to know more about this error code. 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 11 is not turning on or off the way is being commanded, then the powertrain control module would set up this fault code.

 

What causes this problem with the Cylinder 11 Exhaust Valve Control Circuit High?

 

  • The level of the engine oil or pressure might be less
  • There might be restricted oil passage
  • The cylinder deactivation solenoid might not be functioning properly
  • Defective wiring
  • Quirks in the connector
  • The ECM/PCM might be damaged

Replace/Repair These Parts To Fix OBD Code P3488

  1. Electronic Control Unit - ECU monitors the temperature differences in the boost converter with the help of the temperature sensors to prevent the converter from overheating and malfunctioning. Thus, replace faulty ECU immediately.
  2. Throttle Position Sensor - If you find out that there are no misfire codes and a common cause of acceleration stumble is a faulty throttle position sensor. So, it is very important to replace the throttle position sensor with us at equitable prices.
  3. Exhaust Gas Recirculation Valve - The most common symptoms of an issue with the vehicle’s EGR valve is a rough idle. It is not uncommon for EGR valves to malfunction and become stuck in the open position. Poor EGR valve can cause a lot of difficulties, so why not get it replaced at time?
  4. Manifold Absolute Pressure Sensor - If you are experiencing any problem with the manifold absolute pressure sensor, you should replace them immediately. Shop from us now!
  5. Engine Control Module - ECM failures and faults can be very difficult to find and resolve as these are very rare and might require a complete reprogramming of the system to avoid wrong codes from getting stored in the system, leading to misdiagnosis. Replace it now!
  6. Mass Air Flow Sensor - Wrong information sent by the sensor will affect the engine performance adversely as it will not be able to properly read the air entering the system thus hampering the air to fuel ratios directly impacting the engine’s output. Thus, it is advisable to replace them in time.
  7. Powertrain Control Module - Faulty PCM can disrupt the normal functioning of the vehicle by affecting the transmission system and the fuel delivery system. This will cause the system to store wrong OBD error and thus can lead to misdiagnosis.
  8. Diagnostic Tool - In order to be that DIY guy, you need few diagnostic tools to get your car problems pointed out easily. Our diagnostic tools collection will come in handy to do so, so why not have a look?

Easy Diagnosis Of Engine Error OBD Code P3488

Do you wish to diagnose P3488 error code easily? Here are some steps which you should follow in order to diagnose this fault code:

 

You will require some important things like a diagnostic scanner, a digital volt/ohmmeter, and a reliable vehicle information source to diagnose this trouble code. 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 11 Exhaust 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 11 Exhaust Valve Control Circuit and confirm every component incorporated within the circuit which may include a fuse or a fuse-able link. The first step is to 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 on 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 P3488 Code

 

  • There can be some faults in the variable valve timing solenoid
  • The level of engine oil might be very low
  • Negligence in the powertrain control module
  • Wiring problems
