P2135 - OBD Trouble Code

<<See All OBD Codes 

You have the P2135 error code set in your vehicle, and you don’t know what that means? Well, we’re here to take your worries away. This code indicates that an erroneous reading was detected by the Powertrain Control Module from the throttle position sensor A/B, the accelerator pedal position sensor and/ the throttle plate. You can find out more about this code and how to resolve it here, so read on.

You vehicles throttle position sensors are located in the throttle body inlet. The job of the PCM is to conduct comparisons between the sensor readings in order to test their efficiency and punctuality. The sensors send voltage signals to the PCM in relation to the position of the throttle plate. If there’s an incongruence with the readings the PCM will set the P2135 OBD code. The variation in the signal depends on how push the gas pedal is pushed. The PCM module uses the data it gets and compares it to the pre-programmed information, and if it notices that one throttle position sensor is reading half throttle and the other is reading full throttle it will conclude it as an error.

What causes this problem with the TPS Sensor Voltage Correlation DTC?

• Fault with the Powertrain Control Module
• Malfunctioning throttle position sensor(s)
• Problem with the accelerator position sensor
• Open, Shorted, damaged or broken electrical connections in the throttle position sensor
• Faulty electrical connections in the accelerator pedal position sensor
• Distorted top cover of the throttle body not allowing gears to turn as usual
• Fault with the electronic throttle body
• Failed wiring of the accelerator pedal sensor
• Failed engine management computer

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. You can avail free shipping on order s valuing over CAD 99$.
2. Throttle Position Sensor - This is responsible for monitoring the throttle position of the vehicle. A malfunction of this sensor can cause the P2135 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 P2135 code to set. Try to repair or replace it as needed. PartsAvatar has a wide range of APP sensors , order from the comfort of your home and have it delivered right to your doorstep.
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 P2135 code. Shop for electronic throttle body parts on PartsAvatar.
6. Diagnostic Tools - These tools are crucial for diagnosing the trouble codes that may have been set. Buy from a wide range of tools which can help you resolve not just the P2135 OBD error but also various others. Simply order online at PartsAvatar.
7. 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 P2135 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.

For us our customers are everything, and that’s why we will help you to diagnose P2135 code by mentioning some important symptoms below:

Common Symptoms

• Hesitation during acceleration
• Increase in speed even when gas pedal is not pressed
• Rotation Per Minute are higher than usual
• Check Engine Light is on
• Engine may stall

After you know the symptoms of your vehicle’s problem, it becomes easy to detect it and get started with solving it. So, next on our list is few common steps to correct this issue with your vehicle’s.

• Repair or replace the throttle position sensors
• Repair or replace faulty diagnostic tools
• Repair or replace the accelerator pedal position sensor
• Repair or replace the fault circuitry, wires, connectors etc.

Apart from this, you might need to replace other damaged parts too like tsb,rpm,pcm,throttle position sensor,accelerator pedal position sensor,electronic throttle body,throttle plate and more. You can easily find all these parts with us. Not only that you can get these parts shipped to your door free, if your cart value exceeds CAD $99.

Before starting the diagnosis, know that 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. Following are the steps needed to resolve the P2135 fault code:

Start your inspection, and 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 P2135 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 P2135 code

• Mixing up sensor 1 and 2 of the throttle position due to lack of knowledge and replacing the wrong sensor.
• Not following diagnostic steps in order
