How To Fix P2135 Code Dodge Journey

P2135 code definition

Throttle/Pedal Position Sensor/Switch A / B Voltage Correlation

What the P2135 lawmaking ways

This particular trouble code indicates that the Power Control Module (PCM) has detected an erroneous reading regarding the voltages transmitted by throttle position sensor A or B, the accelerator pedal position sensor and or the bodily throttle plate. The PCM expects both throttle position sensor outputs to stay within a logical and fairly close range of one another. The PCM will regularly compare the sensor readings equally a way to exam their efficiency and punctuality. Each throttle position sensor will send the PCM a voltage point in correlation to the position of the throttle plate. The PCM interprets this signal equally how far the throttle plate is open. If one throttle position sensor is reading at one-half throttle and the other is reading at total throttle, the PCM volition set a code P2135 because the voltage readings volition be so remote that it is impossible for the data to be accurate.

The throttle position sensors will be located on the throttle torso inlet. The P2135 code indicates that the voltage readings produced from the throttle position sensors and or the accelerator position sensor are so distant from each other that they must be inaccurate. The signal from each throttle position sensor and the accelerator position sensor must correlate to each other, or a code such every bit P2135 will set.

The throttle position sensor produces a voltage signal according the position of the throttle plate. The farther the plate is opened the higher the voltage output of the throttle position sensor will be. To keep things in perspective the accelerator position sensor operates in an identical way. The accelerator position sensor is near the gas pedal. It volition also send a voltage signal back to the PCM co-ordinate to how far the pedal is pushed downwards. The farther the gas pedal is pushed down, the higher the voltage betoken from the accelerator position sensor to the PCM should become. The PCM expects the readings from each sensor to brandish similar data because they should all exist nether the aforementioned conditions. The accelerator pedal position sensor will tell the PCM how far the gas pedal is pushed downwardly. The PCM will use the data and compare it to its pre programmed parameters. Information technology will basically say " the gas pedal is down sixty% thus far then I know that the throttle plate will have to be open in equal amounts (60%):" Then the PCM will transport a signal to the throttle position sensors to open them up in accordance to how far the gas pedal is pressed down. All of this happens within a fraction of a second.

If the voltage readings of the throttle position sensor and the accelerator position sensor varies too much, so a lawmaking P2135 volition set up.

What causes the 2135 code?

Faulty PCM
Faulty throttle position sensor(s)
Faulty accelerator position sensor
Disruption in the throttle position sensor circuit such equally an open, corrosion, brusque, damaged wiring or broken electrical connections
Disruption in the accelerator pedal position sensor circuit such as an open up, corrosion, poor electrical connectedness, short, damaged wiring or cleaved electric connections

What are the symptoms of the P2135 lawmaking?

Surge or even possibly a hesitation when accelerating
Revving of the engine when gas pedal is not pressed
RPM's are higher than usual
Check Engine Light illumination
Vehicle may stall out

How does a mechanic diagnose the P2135 code?

Back probes the accelerator pedal position sensor and throttle position sensor with a multimeter or scan tool. This allows the voltage output of each sensor to exist viewed. The voltages should be within manufacturer's specifications.
Uses a multimeter to examination the ohm levels of the accelerator pedal position sensor and throttle position sensor. These readings should also be within manufacturer's specifications
Checks TSB's (Technical Service Bulletins) and recalls related to some makes and models for this detail code. A technician must compare the make and model of a vehicle to its applicable recalls and TSB's to determine if there is one that has been implemented.

Common mistakes when diagnosing the P2135 code

I have heard of the throttle position sensors one and 2 being mixed up due to lack of knowledge, resulting in the replacement of the incorrect sensor. Ensure that each sensor is distinguished properly to save fourth dimension and money.

How serious is the P2135 code?

The vehicle may stall out which tin be dangerous if information technology happens in heavy traffic or when going around turns.

What repairs can fix the P2135 lawmaking?

Replacing i or both throttle position sensors
Replacing the accelerator pedal position sensor
Repairing a error in a circuit (throttle position sensor excursion, accelerator pedal position sensor circuit) such equally open up, short, corroded wiring, or poor connection.

In some cases, no parts will need replacement and the PCM will need a flash or update. Consult with your mechanic to discover out if this will apply to your particular make and model of vehicle. The data needed to make up one's mind if a vehicle will require a PCM flash or update will exist establish in the TSB's history of the vehicle.
