Error Code P2137: What It Means & What To Do?

<<See All OBD Codes

The P2137 OBD is defined as a Throttle/Pedal Position Sensor/Switch "B"/"C" Voltage Correlation. This may still not clarify what the issue is, but don’t worry we are here to simplify this code by giving the information needed to not only understand but also resolve the code. This code is set by the Powertrain Control Module when it notices an issue with the sensor or circuit for the sensor. Upon setting the code, it may put the vehicle into limp mode to keep the driver and the vehicle safe from harm.

The Throttle Position Sensor is responsible for understanding how much speed is required by the driver and how fast the speed should be reached. It sends this information to the PCM, the PCM module checks if there’s anything wrong with the signals received and accordingly sets the P2137 code.

What causes this problem with the Throttle/Pedal Sensor Voltage Correlation Code?

• The signals from TPS sensors A and C don’t correlate to each other
• There’s an internal fault present in any one of the sensors
• Loose or broken connections in the sensor circuit or the connector

1. Powertrain Control Module - The brain of your vehicle has to always be in top condition, otherwise things can go haywire. If you have noticed troubles with the PCM, try to repair otherwise replace easily with Parts Avatar. Order from the comfort of your home and have it delivered right to your doorstep in few days.
2. Throttle position sensor - This is responsible for monitoring the throttle position of the vehicle. A malfunction of this sensor can cause the P2137 code to set. It is hence important to fix any damages via repairs or opt for replacement. Buy them online from PartsAvatar and buy good quality products, for a wide range of price from different brands all in one place.
3. Accelerator pedal position sensor - The APP sensor shows the position of the accelerator pedal to the engine control unit PCM. Accordingly the vehicle will move. Having a faulty sensor can cause the P2137 code to set. Try to repair or replace it as needed. PartsAvatar has a wide range of APP sensors, you can avail free shipping on order s valuing over CAD 99$.
4. Throttle plate - This is the largest part of the throttle body, it regulates the airflow in your vehicle. It is a butterfly valve, and very important for the functioning of the throttle body of your vehicle. If you have noticed any issues with it, try to repair, or opt for replacement from PartsAvatar.
5. Electronic throttle body - Is responsible for connecting the accelerator pedal to the throttle. Any malfunction of this can cause the vehicle to not maintain the right speed. It can also cause accidents. Hence it is important to repair the issue or replace it and get rid of the P2137 code. Shop for electronic throttle body parts on PartsAvatar.
6. Engine Control Module - The ECM module is responsible for controlling the fuel mixture, ignition timing, variable cam timing and emissions control etc. of your vehicle so if it’s not functioning properly it can result in the P2137 code setting. It’s best to either repair or replace it and get rid of the code. You can buy required parts online at PartsAvatar Canada.

Next important thing you need to know about are the common symptoms for this obd error code P2137 with your fuel volume control.

If you want to easily diagnose this fault code P2137, then all you have to do is to follow the steps which are mentioned below:

It is essential to diagnose this fault code. Here are some steps which a mechanic should follow for diagnosing the problem that triggered a P2137 code to be stored:

The electronically controlled throttle system is extremely sensitive and hence easily damaged. You can to be extremely careful and patient while handling the components. If you think you need help from a professional, then don’t hesitate to approach a trained mechanic. Upon initial inspection you will find a flat plastic cover on the throttle body, the gears that actuate the throttle plate are located there. There's A small metal gear that protrudes through the housing under the cover, this drives a large “plastic” gear which is attached to the throttle plate. A pin is present in the throttle body housing which helps in centering and supporting the gear. There’s also a pin on top that fits into the “thin” plastic cover, so it’s important that this cover isn’t damaged in anyway. If it is distorted then the gear will be affected negatively and require a full replacement of the throttle body. Now it’s time to get hold of your vehicle Technical Service Bulletins or TSB. This will help you the steps for diagnosis. Connect your OBD scanner to the vehicles diagnostic port and retrieve all the data and freeze frame it. You will have to resolve the codes that were set prior to P2137 if there are any, chances are this code was set due to an issue present with the other codes.

Now you can safely pull the electrical connector out of the throttle body and inspect it for any missing or bent female terminals, be careful while performing this inspection. Any corrosion found will have to be repaired or cleaned via small screwdriver, apply some electrical grease on the terminals and reconnect it. If any parts are missing or not in good condition you can find replacements for them and sort the issue.

Probe the accelerator pedal sensor with a voltmeter and you will find a 5 volts for reference and varying signal next to it. Depress the pedal slowly after turning the key on, the voltage should increase from .5 to 5.0 in a smooth manner. If you find that the voltage spikes, or there no voltage at the signal wire, you will have to replace it. Locate the wire terminal on the throttle body of you specific vehicle, for this you can refer the TSB, once you have found it, probe the throttle body connector for power to the throttle motor. Have someone help you by turning on the key and slightly depressing the pedal, if you find that there's no power present, then it’s an issue with the computer. If there’s power, then it's clear that there’s a malfunction of the throttle body.

View the voltage output of each sensor, they should be within the specifications of the manufacturer. To be able to note these, use a multimeter or scan tool and brack prove the accelerator pedal position sensor and throttle position sensor. Using the multimeter test the ohm levels of the accelerator pedal position sensor as well as the throttle position sensor. Make note if they’re within the range specified by the manufacturer, to know these ranges you can refer the TSB. It’s very important that the TSB should be for the exact make model of your vehicle. Ensure you are able to follow them correctly and all the ranges are within the manufactured specifications.

Common Mistakes When Diagnosing the P2137 Code

• Failed Accelerator Pedal Position (APP) assembly
• Malfunction of the Powertrain Control Module (PCM)
• The Throttle Position Sensor (TPS) has completely failed
• Problems with wiring
