Error Code P0319: What It Means & What To Do?

<<See All OBD Codes

Current cars of today are structured to react in a variation of ways to adverse driving situations, rough roadways often fall along those lines. When the PCM (powertrain control module) recognises a change in crankshaft positioning that it shows to rough road or erratic driving situations, the P0319 code will be stored. Regardless, there could be multiple issues being registered beneath the code.

Rugged Road Hardware permits the engine control module (PCM) to detect if the engine has issues or if the car is driving a rugged road. If the PCM is unable make a decision between both of them, the PCM sets up code P0319.

What causes this problem with the Rough Road Sensor B Signal Circuit?

• Defective Rough Road Sensor (if equipped)
• Misplaced Road Sensor
• Failed Crankshaft Position Sensor
• Faltered Electronic Brake Control Module
• Failed Powertrain Control Module
• Wiring / electrical defect associated to sensors
• Control unit has to be formatted for new road sensor
• Any other probable causes

1. Rough Road Sensor - The programmed computer will keep out any detection from the engine crank position sensor that would regularly target a code that does multiple disengagements when the vibrating is present at a ABS sensor/trigger wheel. This is a very safe method to constantly throw on the Check Engine Light if the crank sensor itself faces a situation where rough road settings cause a vibrating effect.
2. Road Sensor Harness - This kind of sensor harness inspects and follows major systems such as the fuel, ignition, and transmission. They transfer information from the sensor to the ECU for fast and easy repairs. Issues with the ECU connectivity are caused not only when a sensor failure targets the Warning or Check Engine Lights, but also when a wiring harness is failing. It is advantageous to have a professional mechanic test your vehicle anytime you have a Check Engine Light or Warning Light.
3. Crankshaft Position Sensor - If the crankshaft position sensor or its wiring have any issues, it can result in the crankshaft signal to be disengaged as the engine is operating, which can lead the engine to stall abruptly. If you propose that your crankshaft position sensor has an issue, have the car examined by a professional technician.
4. Electronic Brake Control Module - The EBCM is the central control unit for the electronic brakes, so if failing, any electronically controlled brake features, namely the ABS and traction control, are going to be disabled. If you propose that your car’s EBCM may be faced with an issue, have the car inspected by a professional technician.
5. Powertrain Control Module - A failed PCM could get inconsistent to an extent that your car will not be starting or begin stopping when it is running. You will begin to see that fumes are shorted during the running process, thus signalling the fuel system control has failed, so with a PCM that’s not performing correctly, you need to have it restored immediately
   

There is bound to be diverse symptoms that would support this code defect. Determined to learn about some practical symptoms of OBD Trouble Code P0319? Your wish is at our service. Take a glance at them below:

Common Symptoms

• You might deal with problems associated with the car’s traction control
• Anti-Lock Brake System is functioning incorrectly
• The engine may be foundering
• Check Engine Light or Malfunction Indicator Light is activated
• Rugged operation is another probable cause

Approaching certain ways that could actually help you be able to correct this code defect? Parts Avatar is the right place to go. We are open to guiding you, so you have to read through the steps as described below:

It is most susceptible that the rough road sensor on the car must be restored. The ABS and traction control system will probably need to be fixed. Above the worst situations, the engine will actually need to be fixed as well.

Don’t be hesitant if you are still dealing with any problems as our customers always come first and that’s why we provide a valuable range of Rough Road Sensor, Road Sensor harness, Crankshaft Position Sensor, Electronic Brake Control Module, Powertrain Control Module and so much more. We are sure that now all your problems will be resolved.

It is necessary to diagnose this code defect. These are some useful steps that a technician must follow to diagnose the issue that activated a P0319 code that will be stored:

• Start off your diagnosis with a graphic examination of all wiring and connectors. Adjust or restore wiring, connectors, and parts that are damaged, disconnected, shorted or corroded.
• Habitually re-investigate the systematic arrangement after working the adjustments to see if it’s successful. Make sure the systematic arrangement of wiring, connectors, and components, including fuses, all turn up in a usual performing sequence, hook up the scanner, or code reader, to the diagnostic connector and have all the codes stored and freeze frame data documented.
• If having cleared up all codes, then activate the car when doing a visual surveying if the code returns. The code might fail to return immediately, so you may be facing erratic setups. Irregular settings are evidential to be difficult for making a diagnosis and in exceedingly haywire situations might enable such a situation to worsen before making a correct diagnosis. If having the cod reset, begin by surveying the rugged road sensor connectors.
• When using the digital volt/ohmmeter, survey the voltage and ground signals at the sensor connector.
• Adjust or restore circuitry as needed. If all the steps above are agreeable to the inspection analysis square on, when referring to the manufacturer’s visual diagrams, conclude that a defective control module, the anti-lock brake control module and the traction control module are in authority of all the system controllers that communicate with the PCM in accomplishing this system of circuits. The problem may also take place in the controller area of the network.
• In the beginning, we have installed a message-based protocol that was particularly outlined for automotive service.
• The CAN bus network is indeed a complex grouping of wiring harnesses and connectors used as a conduit of data split up between two or more vehicle control modules.
• The motivation for these controllers is to effectively put authority for each of the vehicle’s electrical performances, and the main controller being the PCM.
• A broad stretch of sensors contributes data directly to the control modules and releases an active line of signals directly to the system parts, and all other control modules.
• To further provide: The vehicle capacity sensor transfers an active line of signal to the PCM
• Moreover, you must station some kind of memory saving device, which aims to prevent the PCM and other controllers to lose all memory and need to be reprocessed.
• A specially drawn out diagnostic CAN scanner will display pin values and control module performance, while exceeding the risk of having a major breakdown.
• It has the ability to make for an exact diagnose computer and defeats circuitry problems by surveying the car performance as the vehicle is currently working
• This kind of code is diagnosed by making use of a digital volt ohmmeter that involves independently exploring circuits in the thousands.
• You should survey the control module ground circuits for consistency in the battery ground.
• Failed or disengaged system grounds often cause these kinds of codes.
• It is very helpful to use a supplementary ground cable to diagnose system ground divergences.
• After doing the repairs, engine and transmission ground cables, straps, and wires are sometimes left hanging.
• Make a comparison of your results by using the manufacturer’s sourced values and adjust open or shorted circuits as needed.
• It is often more economical to replace failed wiring instead of trying to take it straight off from the complex web of wiring harnesses.

Common Mistakes When Diagnosing the P0319 Code

If a well understood diagnosis is not controllable, the mechanic will susceptible have one of the camshafts, wheel speed, or crankshaft position sensors replaced, though when not needed.

Driver’s make the mistake of testing the car’s physical parts prior to using a scanner. At the time it seems self-evident that a sensor or wiring harness is damaged, the scanner will snap a more exact picture. In addition, as soon as you carry through with the repairs, you should scan the vehicle once again to make sure all of the problems have been taken care of correctly.
