P0392 - OBD Trouble Code

<<See All OBD Codes

The P0392 trouble code can be defined as Camshaft Position Sensor B Circuit Low Bank 2. The P0392 error code would identify incorrect voltage or waveform from the camshaft position sensor circuit.

If the PCM would perceive an incorrect camshaft position, then the P0392 trouble code would start occurring. The camshaft position sensor is a fixed part which would use an electromagnetic field along with the notches of the camshaft so that the data can be delivered about the camshaft position to the PCM. This would allow the module to easily calculate the ignition timing as well as fuel delivery.

What causes this problem with the Camshaft Position Sensor "B" Circuit Low (Bank 2)?

• Issue of oil or engine fluid leaking on electrical connectors, wires or sensors
• There can be a leakage in the fluids which can cause failure in the camshaft sensor
• Defects in the crankshaft sensor
• The powertrain control module might start failing
• Quirks in the camshaft position sensor "B"
• Sensor harness might be opened or shorted
• Some faults in the electrical connections
• The starter might be defective
• The wiring to the starter can be poor
• Defaults in the battery

1. Engine Control Module - Defective car Engine Control Module can be a major reason why P0392 code depicts. So, make sure to replace it online so that you don’t have to face any further issues.
2. Camshaft Position Sensor - Everything is okay with the Fuel Injector and still OBD code P0392 triggering? Then there must be some defects in Camshaft Position Sensor. Replace them as soon as possible.
3. Fuel Injector - P0392 code flashing? Get your Fuel Injector inspected from a mechanic.
4. Crankshaft Position Sensor - If everything is alright with PCM, then there is surely some defect in Crankshaft Position Sensor. Get it replaced before the situation gets worse.
5. Exhaust System Parts - P0392 code can display due to some issues in the Exhaust System Parts. So it is very important to replace the damaged Exhaust System Parts with us at equitable prices.
6. Ignition Coil - Do you remember when was the last time you got your car Ignition Coil checked up? A dirty Ignition Coil can cause a lot of issues like displaying P0392 code.
7. Cylinder Head Gasket - Poor Cylinder Head Gasket can cause a lot of difficulties, so why not get it replaced at time?
8. Powertrain Control Module - Are there some faults in your Powertrain Control Module? Don’t waste time and get them replaced or else P0392 code can turn up.

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
• There can be lack or loss of engine power

The repairs which you will have to do to correct this fault code are simply straightforward; you can surely pinpoint the necessary repairs on the basis of your diagnosis. Have a look at some common fixes:

• The code should be validated by clearing it and then should be retested
• Carefully check the wiring and connections
• Make sure to repair and replace any components, connectors, fuses or wires
• The leaking fluids should be corrected
• You can always use an oscilloscope to look for inconsistent waveforms in the camshaft, distributor and crankshaft sensors
• Carefully test and replace the camshaft sensor and crankshaft sensor if their voltages are not to manufacturer's specifications
• The system continuity and resistance should be inspected properly
• Replace and reprogram the powertrain control module

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 electric battery, reluctor, automatic transmission module, injection 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:

• If you want to diagnose the P0392 code, then you should use an OBD-II scanner
• After that a visual inspection of all wiring should be performed
• Any needed repairs or replacements must be done before clearing the codes and retesting
• If the code reappears, the mechanic will have to monitor waveforms and look for inconsistency in the performance of the camshaft, distributor and crankshaft sensors
• They will also look for signs of fluid leaks and perform voltage testing on the sensors. This means that repairs require the scanner, an oscilloscope, and a digital ohm meter

Common Mistakes When Diagnosing The P0392 Code

• There are a lot of technicians which might blame the sensor behind the appearing of the P0392 fault code without actually first testing the entire system
• There are a lot of areas where failure may occur as the ode covers the entire circuit for the camshaft position sensor, a thorough diagnosis is needed
• The camshaft position sensor interacts with the reluctor ring at the end of the camshaft, and when it passes the sensor it interrupts the pattern from the sensor to the PCM. This is something that has to match the pre-programmed timing in the PCM and so it is important that you diagnose the cause carefully
