Guide To P0386 OBD Error Code Solutions

<<See All OBD Codes

The trouble code P0386 would mean that the computer of the vehicle has detected excessive voltage from the crankshaft position sensor which has exceeded the specifications set by the manufacturer.

The P0386 error code can be described as Crankshaft Position Sensor B Circuit Range Performance.

The meaning of P0386 trouble code is that the voltage signal at the crankshaft position sensor is actually higher than what the manufacturer has set. It would indicate a voltage signal of 10% higher than the standards of the automaker. This fault code would be stored in when the voltage higher than the normal has been detected.

What causes this problem with the Crankshaft Position Sensor B Circuit Range Performance?

• Defaults in the crankshaft position sensor B
• A short or open in the sensor’s wiring harness
• A broken reluctor wheel or missing teeth
• There can be poor connection in the sensor circuit
• Defaults in the powertrain control module
• The crankshaft sensor might be faulty
• The reluctor ring might be broken
• Reluctor ring dislodged/stripped from its stationary location
• Short can be cause because of wiring harness chafing
• Wiring open in CKP circuit

You might be thinking that how would you diagnose these problems? We at Parts Avatar Canada would help you diagnose the major symptoms easily.

Common Symptoms

• The check engine light can start turning ON
• Intermittent stalling
• The car may not be able to start properly
• Intermittent engine misfires
• There can be lack or loss of engine power
• Issue of rough idling
• The overall fuel economy might start decreasing
• Choppy acceleration

Looking out for some ways with the help of which you can correct this fault code? Then you have arrived at the correct place. We are here to help you out, so you must check out the steps mentioned below as follows:

• If there is a failure in the crankshaft position sensor, then it should be replaced
• If there is some fault in the wiring, then it should be repaired
• Replace the powertrain control module
• Carefully clean the corroded connectors

There is no need to get strained if your OBD Code is still flashing up as we are here at your service. Have a look at our superior variety of rpm, reluctor ring, timing components and many more. Now all your problems would vanish within no time.

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

• The first thing which you should do in diagnosing the problem will be to connect an OBD-II scanner so that you are able to read the codes stored in the car’s computer.
• The codes should then be cleared by the mechanic and test drive the vehicle.
• However, a test drive may not be necessary if the mechanic observes that the RPM reading is 0 while the engine is running, or that the RPM reading is inaccurate during starting.
• After that you must do a visual inspection of the CPS/CPK sensor, connector and wiring followed by a signal check using a scope.
• Reference voltage should be 5 volts for most vehicles.
• It may be necessary to disconnect the sensor and test for signal outside the vehicle, as well as testing the circuit for voltage.
• If the sensor tests bad, it must be replaced. If the sensor tests good but the circuit has no signal, the mechanic should check for and repair any shorts or damaged wiring.
• After repairs, the sensor should be replaced and the vehicle test driven to determine normal operation or recording.

Common Mistakes When Diagnosing The P0386 Code

• Generally, most of the people might make mistake of not fully inspecting the wiring harness and connectors for damage and corrosion. This is the most common cause of intermittent problems.
• One another mistake which can occur is damage to the gear teeth, reluctor ring or sensors which can be caused during timing belt replacement
