Error Code P064E: What It Means & What To Do?

<<See All OBD Codes

What is P064E code? What happens when a P064E code is stored? If this code is stored, it means the PCM has found error with the heated oxygen sensor circuit for bank 2. Other controllers will also identify the error in PCM which makes the P064E code to be stored. Bank 2 refers to the bank of engine which lacks cylinder 1. The H2OS can be protected using nuts that is linked to the exhaust pipe.

Exhaust gas is made to reach the upstream HO2S where they flow into the steel housing. Ambient air is drawn and heated to produce voltage. Variation in voltage causes fluctuation in voltage. Change in voltage is identified by the PCM and it determines if the engine is rich or lean. The upstream HO2S typically varies between 100 and 900 millivolts when the PCM is closed. As the engine enters open loop, control module processor is responsible for several duties. Input and output signals of H2OS is self- tested and monitored regularly. H2OS self-test is started when PCM is energized. If the PCM finds error in GO2S functionality, P064E code will be stored and the MIL we be lit. If the PCM detects problem with on-board controllers, again P064E code will be stored in the vehicle. Depending on the severity of the malfunction, you will require multiple failure cycles for MIL illumination.

What causes this problem with the Internal Control Module O2 Sensor Processor Performance Bank 2?

• Imperfect controller or programming error.
• Damaged HO2S.
• Rich exhaust conditions.
• Burnt, broken, or disconnected wires /or connectors.
• Leaks in the engine exhaust.
• A poor controller power relay or blown fuse.
• Open or shorted circuit and connectors.
• Deficient control module ground.

1. Exhaust System - A leaky exhaust system has to be replaced or repaired in order to avoid the P064E error code.
2. Oxygen Sensor - If your oxygen sensor is broken or damaged, make sure it is replaced with the right replacement part from Parts Avatar.
3. Blown Fuse - A broken or short-circuited fuse can cause disturbance to your engine system. Get them replaced as needed.
4. Powertrain Control Module - Majority of the OBD error code arises due to a damaged or defective PCM. Resolve the issue as needed.
5. Engine Control Module - If you are looking for the right replacement part, you can get them at Parts Avatar at best prices online.
6. Multimeter - This can be one of the common causes for failure in the system. Fixing this component can help you to get rid of the P064E code.

It is vital to know the symptoms of an issue as only then you would be able to solve the problem. So that’s why we have listed out some major symptoms of OBD Code P064E here:

It is essential to diagnose this fault code. Here are some steps which a mechanic should follow for diagnosing the problem that triggered a P064E code to be stored:

• Diagnosing a P064E code is quite challenging. If there is no necessary equipment, then it will be impossible to complete a successful repair.
• If there are ECM/PCM codes they have to be diagnosed before checking the P064E code. Connect the scanner to your vehicle and recover all the codes and data. Write down this information for further use. If the PCM enters readiness mode then it will be difficult to diagnose P064E code. Make the conditions to worsen and see if the code appears.
• TSB can be helpful to recover the stored information. If you find the right TSB it can help you in a major way. Also use the vehicle information to get connector face views, connector pinout charts, component locators, wiring diagrams, and diagnostic flow charts related to error code. Replace the blown fuses and test them with the help of circuit.
• If all components function properly, check the wires, joints, chassis and engine ground junction. Visually inspect for any damages and they should be replaced immediately.
• There can also be a problem with the controllers where you will have to buy reprogrammed controllers through aftermarket resources.
• Ensure that the vehicle runs effectively before diagnosing HO2S. To supply HO2S system with voltages, some automakers use fused circuit. Use Digital voltmeter Ohmmeter to check fuse. If they are working well, then locate the HO2S and place them on safe stands. With the help of wire diagrams locate your circuit which is used to supply battery voltage.
• Reconnect the HO2S if both voltage and ground are present. Start the engine, test drive it and allow it to stay idle. The upstream of HO2S should cycle from rich to lean.
• P064E can mainly arise due to a damaged controller or programming error where the negative side is connected to the ground and the positive side is connected to battery voltage.

Common mistakes when diagnosing the P064E code

• Faulty PCM.
• Wire problem.
