This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic. This code occurs when the voltage limits are not within specifications programmed into the ECM. Monitors O2 sensor data to see if the voltage is switching back and forth between low and high at a fast rate compared to other sensors.

Check the removed O2 sensor for damage from a defective catalyst and replace the catalyst if it is faulty. The voltage output from the O2 sensor may point to engine and exhaust problems causing the O2 sensors to give erratic output voltages. The ECM may stay in open loop until the O2 system is repaired or the O2 sensor starts working again causing extended rich conditions that could possibly damage other engine components. Replacing the O2 sensor for bank 1 sensor 2.

The O2 sensor circuit for bank 1 sensor 2 is used to give a voltage feedback to the ECM to control the fuel and provide information about catalyst operation.

Request Travis.When your car's 'Toyota Avensis 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.

So you should chech it on our car models. 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.

From reading this forum it seems that Denso branded sensors are the brand of choice when used in place of the Toyota sensor from the dealership. The Denso site and the AutoZone site gives: Denso and as the replacement parts. Has anybody used these parts with any luck?

Are these a direct plug-in or are they a universal type plug that has to be wired? Did they fix the problem or is this a catalytic converter problem? It seems odd to me that both sensors or cat converters for that matter would fail simultaneously.

I have already done a couple of the cheap fixes. If there is anything else I can try please let me know.

I have used the ones off amazon and they worked just fine. They are not made by Denso though they are made in America with authorization to use Denso's name so it is hit and miss, I have to do my bank 1 sensor 1 upstream for a 3rd time after it was in for only a year. But if you are going to do your downstream ones do the mode that others have done using a sparkplug antifouler thing do a search in the forum here about it that is what I am going to do next time.

I replaced the O2 sensors with the above mentioned Denso sensors purchased from Amazon. I have now driven about mi. I'll keep this thread updated. It looks like most people who have trouble have their CEL come back on after about a week. Here's hoping that doesn't happen. EDIT: After driving about mi. CEL came back on.Your car has oxygen O2 sensors that measure the amount of oxygen present in your exhaust. Based on the measurements taken, the O2 sensor will fluctuate between a high rich and low lean voltage reading.

If you are seeing code P, it means that the O2 sensor behind your catalytic converter on bank 1 is malfunctioning. Driving with trouble code P is acceptable but only for a short period of time. Driving with this code for an elongated period of time could result in greater engine or catalyst damage. Replacing the O2 sensor without checking for any intake or exhaust leaks or loose connections.

For error code P, one or more of the below repairs may be needed to solve the underlying issue.

Have p code can it be catalytic converter or fuel pressure. Please show me where is located the catalytic 02 sensor for my Dodge Ram 4.

Also need to now where is located the vacuum. If the code is emissions related, it cannot be cleared by a scanner. The light will come back on if the problem persists.

Hottest Questions. Previously Viewed. Unanswered Questions. Toyota Sequoia. What does code p for Toyota sequoia means? Wiki User This refers to the second oxygen sensor on Bank 1. Bank 1 is the same side of the engine that cylinder 1 is on, the very front cylinder on the drivers side. It could need to be replaced, or there could be a short to voltage on the O2 signal circuit, or it could also be that the connector has been corroded, and needs to just be cleaned.

Wiring Harness Damage — The wiring that goes to the front and rear oxygen sensors is very susceptible to damage. This is due to the fact that O2 sensors are under the chassis where they are subject to punishment from road debris, and they are subjected to a lot of exhaust heat. That can throw this code. Wrong O2 Sensor — If you are getting P after having recently replaced your Oxygen sensor, it may be that the replacement is wrong or bad.It is typically caused when the O2 Sensor voltage is not within normal operating range.
