We recommend Torque Pro. The catalytic converter is an emissions-control device. Unburned hydrocarbons fuel and oxygen combine, producing carbon dioxide, and nitrogen-oxides recombine, producing inert nitrogen and oxygen, for example. The ECM engine control module monitors catalyst function by measuring oxygen levels in the exhaust after the catalytic converter.
A normally-functioning TWC will effect a change in oxygen content downstream as it chemically combines various exhaust components, resulting in a slowly variable HO2S reading downstream, slowly cycling between 0 V and 1 V. If the HO2S does not respond with voltage over a certain threshold, indicating lower oxygen content, the ECM determines this to be a fault, sets a diagnostic trouble code DTC and illuminates the malfunction indicator lamp MIL.
Depending on year, make, and model, DTC P may have number of causes. Here are some of the most common.
Oxygen vs Voltage by Clamothe via Wikimedia. Catalytic Converter by Stahlkocher via Wikimedia. You will probably not notice any drivability symptoms, though your fuel economy may suffer if the failure mode puts the engine in open-loop mode. Though this DTC refers to an oxygen sensor, do not simply replace it as a matter of course. The sensor may be at fault, but do not condemn it unless you have done the rest of the tests.

How is the P code repair? Start by checking the "Possible Causes" listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector's pins. What is the cost to diagnose the P code Labor: 1. The auto repair labor rates vary widely across the country, and even within the same city.
How much do you know about cars? Take the AutoCodes. When is the code detected? The oxygen sensor varies the voltage over a range from about 1, mV when the exhaust is rich, down through about 10 mV when the exhaust is lean. The PCM compares the stored HO2S voltage samples taken within each sample period and determines if majority of the samples are out of the operating range.

Repair Importance Level: 2.Meaning of P engine trouble code is a kind of powertrain trouble code and when your car's 'P Check Engine' light comes on, it's usually accompanied by a sinking feeling in the pit of your stomach.
The light could mean a costly problem, like a bad catalytic converter, or it could be something minor, like a loose gas cap. But in many cases, it means at minimum that you'll be visiting the car dealer to locate the malfunction and get the light turned off. The crankshaft sensor signals the fuel injection computer or the ignition control when the cylinders are firing. This causes the ignition coil to provide a spark and the injector to inject fuel into each cylinder at the right time.
If either sensor isn't working correctly, the car will run rough and the engine will be less efficient. In later car models, the car's computer can usually keep the vehicle running, but the engine warning light on the dashboard goes on to warn the driver. Is the fuel pump sometimes not priming when you turn the key to ON II?
Start by measuring the fuel pressure and checking whether you have bright white-bluish spark at all four plugs. The mechanical timing is also something that you should check, as we mentioned above.
P the main thing to check is to verify the operation of the VCT solenoid. You're looking for a sticking or stuck VCt solenoid valve caused by contamination.

If one of these reasons for P code is occuring now you should check P repair processes. Now don't ask yourself; What should you do with P code? The solution is here :.A problem caused by wiring error, an issue in the HO2S Heated Oxygen sensorfuel pressure, injectors, or an intake leak. This error code is a generic trouble code, meaning it applies to all vehicles equipped with OBD-II system, especially those made since up to present.
Specifications on the definition, troubleshooting, and repairs, of course, vary from one make and model to another. This code means the Oxygen 1 sensor 2 to the PCM powertrain control module, also known as ECM or engine control module is getting too much in the exhaust stream due to an open circuit or defective sensor, causing a lean signal reading to the PCM.
This error code is caused by a couple of factors, such as the PCM attempting to correct the output by going rich while monitoring the signal, or an error in the wiring or connection caused by damage which results to a lean output. As with most error codes, technicians diagnose this code by using a scan tool to document the code s present in the PCM.
Lastly, they will disconnect the O2 sensor and check for proper output voltage, as specified for the vehicle by its manufacturer. Repairs for this code are as easy as its diagnosis. Of course, it requires a thorough diagnosis for a proper repair.
Repair procedures include:. One of the most common mistakes when addressing this code is replacing the O2 sensor before checking for leaks in the exhaust. Thus, it is required to diagnose the exhaust and repair the leaks or replace to solve the leaking problem first before replacing the sensor. This code can be generated by a vehicle that is having an exhaust leak between 1st and 2nd O2 sensors.
The added oxygen that enters the exhaust will cause erroneous signals from the sensor that is downstream from the leak. Remember me. Table of Contents. Subscribe to our mailing list.This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.

This means that the O2 sensor in bank 1 sensor 2 indicates either too much oxygen in the exhaust stream, an open circuit, or a defective sensor which causes a lean signal to the ECM. The engine control module ECM got a lean voltage signal return from the bank 1 sensor 2 oxygen sensor. The ECM attempts to correct the output by going rich while monitoring the signal, sets code, and turns on the Check Engine Light if the output stays lean.
Code P is an indication that the O2 sensor does not detect the catalyst efficiency and can cause the vehicle to fail an emission test.Kisi ko kaise bhule shayari image
Code P can be generated by a vehicle that has an exhaust leak between the first and second O2 sensors. The added O2 entering the exhaust will give erroneous signals from the sensor that is downstream from the leak.
