Guide To P061B OBD Error Code Solutions

<<See All OBD Codes

The OBD code P061B is stored when the PCM detects an internal performance error in the engine torque monitoring system. There may be other controllers who may have also detected this internal performance error of the PCM with the engine torque monitoring system. These systems can also store this error code upon noticing such a discrepancy. There are various self-test duties carried by the internal control module monitoring processors, they also check for overall internal control module accountability. The Engine torque has a calculation system which has input and output signals. These are subject to self-test and the PCM as well as other related controllers constantly monitors them. Some of the modules that are in close interaction with the engine torque monitoring system are the transmission control module (TCM), traction control module (TCSM) amongst other controllers.

In a vehicle the engine torque is monitored by the PCM. The Powertrain Control Module does this by using input signals received from the Mass Air Flow sensor (MAF) as well as the Accelerator Pedal Position (APP). They are both responsible for providing different information. APP sensor calculates the desired or approximate required engine torque, whereas the MAF sensor calculates the actual engine torque. When the engine is switched on the PCM is energised, then the internal engine torque monitoring self-tests start. The Controller Area Network or CAN runs internal controller self-tests and also compares signals from every module to make sure that they all are functioning well. These tests are performed at the same time, if the PCM detects any incongruence with the desired torque and actual torque (more than 50-Newton meters for more than 1-second), it will set P061B code. The Malfunction Indicator Lamp may also be illuminated, however it may take multiple failure cycles for it to light up, depending on the severity of the issue.

What causes this problem with the Internal Control Module Torque Calculation Performance?

• Fault in the Throttle Valve Control Servo
• Open or shorted harness of the Throttle Valve Control Servo
• Bad electrical connection of the Throttle Valve Control Servo circuit
• Powertrain Control Module (PCM) has failed
• Corroded connector of electrical MAF sensor
• Clog in the air filter element
• CAN harness connectors are open or shorted

Here are some steps which you should follow in order to diagnose this fault code:

• Diagnosing the P061B error code can be tricky. It can pose a challenge for the most experienced mechanic too, having the right tools enables in faster and accurate diagnosis. Reprogramming can also become a requirement. Ensure you have all tools ready before proceeding.
• Tools required include a diagnostic scanner, a digital volt/ohm meter (DVOM), oscilloscope and a source of reliable vehicle information will be required. The oscilloscope can be particularly helpful when testing sensors of APP and TPS.
• If you find any power supply codes related to ECM/PCM, you will have to rectify them first. Any MAF/APP sensor or Throttle Position Sensor TPS codes will also have to be diagnosed and accordingly repaired.
• Get your TSB and follow recommendations in for to test the MAF, APP, as well as TPS sensors. Replace all malfunctioning components.
• Now proceed to doing all the preliminary tests. Connect your code scanner to the diagnostic port of your vehicle. Now retrieve all the stores codes, and freeze frame them. Make sure you note them down in order too, this will help you refer if the codes are intermittent. Now erase all the codes and go on a test-drive. If the PCM enter readiness mode then the issue will have to unfortunately worsen as it may be an intermittent code. If the code resets, then continue with diagnosis.
• Look through your vehicles TSB and find the code and check symptoms. Ensure that the vehicle model is correct, and read through instructions in it. Information is your greatest asset when diagnosing P061B error code.
• Refer your vehicle information source and obtain connector face views, connector pinout charts, component locators, wiring diagrams, and diagnostic flow charts related to the code and your vehicle model.
• Using the DVOM test controller power supply fuses and relays, ensure the circuit is loaded when starting the test. Replace any blown or shorted fuses as needed. They seem to be functioning correctly, visually inspect the controller related wiring and harnesses. See if they need any repairs or replacement and proceed accordingly. To obtain ground locations, use the vehicle information source. The ground integrity can easily be tested via DVOM.
• Continue your visual inspection of the system controllers for any water, collision damage or heat damage. The ones damaged by water will have to be replaced for sure.
• If upon doing all tests, you find that the controller power and ground circuits are intact, then it’s mostly a defective controller or a controller programming error causing this OBD error. Replacement of controller will mandate reprogramming, get help of a professional if you don’t know how to do that.

Common Mistakes When Diagnosing the P061B Code

• Failed Powertrain Control Module (PCM)
• Issue present with the wiring
