This situation causes an over-advanced condition that occurs either during retarding or advancing the camshaft timing. The P code is triggered when bank 1 has an over-retarded timing condition that occurs either during retarding or advancing. The P code happens when bank 1 camshaft has an over-advanced timing condition that occurs either during retarding or advancing.

Using the bidirectional scanner , command the timing valve solenoid control valve to open and close, then see if camshaft timings change. If they change, it means the valve is not the problem. The P code occurs when the crankshaft and camshaft signals are out of time.

The P code is triggered when bank 1, sensor 2 of the O2 sensor heater circuit is faulty. The P code happens when the mass airflow MAF sensor does not perform within the standard expectation and sends a lower signal than usual due to low voltage.

An increase in MAP indicates an increase in engine load. P means that the signal voltage from the intake air temperature IAT is above 5V, which is more than the expected range.

The value varies from one car to another, but the code may come when the voltage hits 0. P OBD2 code means the PCM has detected that the engine has not attained the required temperature despite it is on for enough time to reach that temperature.

P triggers when the ECM has determined a low voltage condition in bank 1 sensor 1; i. Usually, when the O2 heater attains operating temperature, the O2 sensor switches based on ambient temp. If ECM determines that the O2 sensor took too long to switch, this code is set. It applies to the first sensor of bank 1. P means that the ECM has determined a low voltage condition in bank 1 sensor 2; i. Basically the same as P The P code means the heated O2 sensor in bank 1 sensor 2 gives a higher voltage reading than it should.

For most vehicles, the code comes when voltage exceeds 1. P means when the O2 heater attains operating temperature, the O2 sensor switches based on ambient temp. It applies to the second sensor of bank 1. P triggers when the O2 heater attains operating temperature, O2 sensor switches based on ambient temp. It applies to the second sensor of bank 2. P indicates that there is a lean condition in bank 1; i.

It could be one or more cylinders. The P code occurs when the PCM has detected a misfire of less than 1, revolutions after startup. The P code happens when the PCM has detected that the crankshaft position CKP sensor does not produce pulses or the pulses are not normal.

It uses these pulses to determine the position of the crankshaft. Main Symptoms: The most notable symptom is engine pinging when the vehicle is at high speed or under load. TIP: To quickly find an error code, use your browsers Search function. Home Contact Support Knowledgebase.

Where manufacturers feel that a code is not available within the generic list, they can add their own codes. The definitions for these are set by the manufacturer. Remember to always double-check the error code from different sources before making repairs to your vehicle. Below is a very common error code called P This is a typical error code and we can find out its meaning.

If we look at the next number, we can find that it tells us that there is an emission control problem. The last digits tell us what type of error code in the emission category it is. In this case, the last digits are 20, which means that there is a problem with catalyst efficiency in Bank 1. All this is only to explain the structure of the OBD2 codes.

You can do this research with all the error codes in your vehicle. Here is a list of all the different common error codes that you will most likely find when you read the error codes from your car. We have detailed troubleshooting instructions for some of the error codes. So if you find your error code in the list and it is covered by a link, follow it and you will find some good information about the error code. These costs can be reduced if you get an OBD2 code scanner for home use.

There are many different scanners in all price ranges on the market. However, buying a well-functioning scanner does not have to cost you thousands of dollars. One scanner that we have found to work really well for us is the BlueDriver Bluetooth scanner, which you can use with your smartphone and read advanced error codes from most cars on the market. Make sure the scanner is compatible with your car before you buy it.
