Error Code P2164: What It Means & What To Do?

<<See All OBD Codes

Alarmed? Don’t know where to start from? Well, Parts Avatar has listed it all for you! Here’s how you can solve the error code. The throttle/pedal position sensor "B" maximum stop performance is also known as the OBD-II code decreased engine performance. One can observe that the throttle position sensor/switch can be found on the throttle body of the intake manifold and the pedal position sensor/switch as a part of the accelerator pedal assembly. These sensors present inform engine control module (ECM) about the desired speed of the driver as well as it guides on how to achieve that speed too. The code P2164 is set by the PCM when it detects an error with this sensor or the circuit for the sensor. At times, the PCM also restricts the speed of the vehicle to 20 miles per hour or less ("Limp home mode") in order to prevent the engine and the driver. It does so because of the control module’ inability to accurately identify the engine performance requested.

It should be noted that, whenever the powertrain control module (PCM) identifies a maximum stop/wide open throttle position sensor voltage signal (from the sensor designated B) that fails to match the programmed parameters, the code P2164 is set. The malfunction indicator lamp (MIL) illuminates too. Generally, the PCM enters the limp in mode, when the code is stored. The engine acceleration could be restricted (if not completely limited) in this code.

What causes this problem with the Throttle/Pedal Position Sensor B Maximum Stop Performance?

• A distorted TPS or PPS
• Loose or shorted circuits between the TPS, PPS, and the PCM
• Burnt electrical connectors
• A damaged DBW actuator motor

1. Powertrain control module - It is because of a malfunction in the powertrain control module, downward emissions are likely to follow besides other issues like a sluggish engine crank, failure in the emission system etc. We advise you to get your faulty PCM changed now by simply logging into Parts Avatar.
2. Throttle position sensor - Vacuum leaks commonly accompany a damaged throttle position sensor. This further triggers pressure problems in the throttle body leading to undesired flow and disturbance in the fuel and air mixture. Tune into Parts Avatar to change or mend your throttle position sensor.
3. Throttle position switch - A bad throttle position sensor gives away numerous signs such as intermittent flashing of check engine light and engine stalling for no explicable reasons. A faulty throttle position sensor becomes the cause of many problems such as problems in changing gears and a considerable fall in the fuel economy.
4. Throttle body - A failing throttle body can lead to a number of issues in the working of the system, majorly vacuum leaks which may cause air disruptions due to imbalanced air flow. Carbon deposits and Grime buildup in the throttle are the early symptoms of a failing throttle body.
5. Intake manifold - A bad intake manifold leads to many problems primarily engine overheating and coolant leaks. Misfires, decrease in power and acceleration and reduction in the fuel efficiency are also issues that arise because of dysfunctional intake manifold.
6. Accelerator pedal assembly - A faulty accelerator pedal assembly becomes an interference in the efficiency of the engine and inconsistency of the engine throttle. It also causes problems in the fuel efficiency of the engine.
7. Engine control module - Hate the halts? Well, it could be triggered due to a fault in your ECM. It should be noted that a malfunctioning ECM often leads to a no start condition. We advise you to get your engine control module changed as soon as possible.
8. Pedal position sensor - Whenever a problem with the pedal position sensor exists, the vehicle's ability to consistently accelerate or decelerate as directed by the driver is reduced. Repair or replace your pedal position sensor as soon as possible in order to avoid further complications caused by the error code P2164.
9. Pedal position switch - A corroded or open pedal position sensor is likely to disturb the overall functioning and performance of the pedal position switch. Log into Parts Avatar right now, if you want to get rid of these problems.
10. Electrical connectors - Have you been experiencing problems with the battery terminals? Or a loss in electrical power? It is caused due to problems in the electrical connectors. Tune into Parts Avatar to get your hands on the best quality electrical connectors available across the country.
11. Dbw Actuator motor - Throttle hesitation, poor fuel economy and engine stalling is often caused after a malfunctioning DBW actuator motor. Don’t know where to look from? Don’t worry, we are just a click away!
12. Automatic transmission parts - This complex system in the vehicle, if not fixed in time can lead to expensive after repairs. Mend or restore your system just in the right time in order to avoid problems with the automatic transmission parts.
13. Fuel shutoff valve - Facing the error code P2164? It could be due to a fault in your fuel shutoff valve. Not only this, it is likely to invite problems while accelerating and black smoke emitting out. We advise you to get your fuel shut off valve changed or repaired right away before it's too late.
14. Digital voltmeter - Suddenly noticing erratic or irregular readings from the voltmeter? See the error code P2164 flashing? If you want to get rid of this, you simply need to repair or replace your bad digital voltmeter.
15. Ohmmeter - Weary or an unsound ohmmeter can often be problematic. It monitors the lights as well as few components in the system. Also, a faulty one can lead to dimming of the lights or pulsing of the lights. So to add some spark to your ride you definitely need the perfect quality Ohmmeter offered at Parts Avatar. Isn’t that just the perfect deal?
16. Throttle Actuator Motor - It can be seen that all the time, the engine responds to throttle pressure applied by the driver without stumbling or hesitation. Also, when the throttle actuator motor is damaged, it can send inaccurate readings to the ECM and cause more fuel to be sent inside the motor than air. So replacing one can be one of the wisest decisions to avoid a problematic system.
    

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 P2164 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 P2164 code to be stored:

The vehicle information source should be checked for technical service bulletins (TSB) that match the make, model, and engine size of the particular vehicle. The symptoms and codes stored should also parallel. If a matching TSB is found, it is definitely going to help you dramatically while performing the diagnosis.

Begin with a visual inspection of all system related wiring and connectors. Also, check the throttle plate for any traces of carbon buildup or malfunction. All the carbon should be cleared from the throttle body according to the recommendations of the manufacturer. Mend or restore all the damaged wiring or electrical components as per the requirements. A retest should be performed of the DBW system.

An updated diagnostic scanner, a digital volt/ohmmeter (DVOM), and a reliable vehicle information source is all that will be needed to accurately diagnose this code.

Connect the scanner to the vehicle diagnostic port in order to restore all stored trouble codes. All of them should be written down along with the freeze frame data as it helps a lot during the procedure is being performed. It proves to be extremely helpful if the P2164 is intermittent. Next, you should clear the codes and test-drive the vehicle to see if the code is reappears.

All the voltage spikes and irregularities, between the TPS, PPS, and the PCM should be detected using the scanner data stream, if the code reappears. The data stream should be narrowed to display only the relevant data for a quicker response. In case , if you fail to find any spikes and/or inconsistencies are detected, the DVOM should be used to retrieve live data at each of the sensor signal wires. Well, in order to restore the live data with the DVOM, the positive test lead should be connected to the appropriate signal wire and the ground test lead to the ground circuit. Observe the DVOM display while working on the DBW. Investigate and search for spikes in voltage as the throttle activates slowly from the closed position to wide open throttle. Iit should be noted that the voltage mostly ranges from .5-volts at closed throttle to 4.5-volts at wide open throttle but the vehicle information source should be referred to for exact specifications. If you detect spikes or other irregularities, a damaged sensor (being tested) should be suspected. The oscilloscope can also be used as it is a great tool for testing sensor operation.

If the sensor is operating as desired, all the related controllers should be disconnected and probe the individual circuits with the DVOM. The system wiring diagrams and connector pinout charts extremely help while establishing which circuits to test and where to locate them on the vehicle. The system circuits should be repaired or replaced as required.

A damaged PCM or a PCM programming should be suspected, only if all system sensors and circuits are found to be working in order. At times, various manufacturers demand that the throttle body, throttle actuator motor and all throttle position sensors should restored as a single unit
