Error Code P0709: What It Means & What To Do?

OBD Code P0709 - Transmission Range Sensor A Circuit Intermittent

<<See All OBD Codes

Fearing the OBD error code P0709? Well, here’s how you can simply comprehend and crack the error code. Varying slightly among makes and models, the meaning of P0709 usually signifies that the PCM (powertrain control module) has identified an error in the shifting mechanism of the vehicle. It determines the situation where the transmission range sensor fails to determine the gear you put the vehicle into, consequently leading to the PCM failing to inform the engine about what to do as far as RPMs, fuel delivery, timing, and other actions. For example, when the shifter indicates about being in drive but the sensor informs the PCM about being in park. Thereby leading to the information being received from the speed sensor, transmission shift solenoids, torque converter lock-up solenoid and numerous sensors failing to match the current actions.

The transmission control module (TCM) and the engine control module (PCM) are informed by the transmission range sensor (also known as the PRNDL input and/or neutral safety switch) about the transmission being in park, reverse, neutral, drive, low, 2nd, 3rd etc. Linked directly to the manual valve of transmission, thereafter when the shift lever is moved from park to drive the transmission range sensor plays the role of communicating this essential information to the above stated vehicle control module systems. The PCM stores the code P0709 when the input from the transmission range sensor is registered as impractical or irregular.

Easy Diagnosis Of Engine Error OBD Code P0709

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

 

  • To begin with, it should be noted that an accurate diagnosis of the error code would require an appropriate wiring schematic of the vehicle.
  • The structure and arrangement of the transmission range sensor and the components linked to it vary among vehicles so it becomes important to be informed in order to be able to precisely address the problem.
  • Firstly, utilizing an OBD-II scanner, the technician should verify the presence of any coinciding codes. Each and every code should be diagnosed and mended in the specific order in which they occurred.
  • The codes should next be cleared and the vehicle should be test driven to see if they return.
  • Perform a visual inspection of the PCM wirings and connectors, any corroded, damaged or short-circuited components should be restored or repaired and the vehicle should be tested to see if the code reappears.
  • It is recommended to use a range sensor diagram to locate the associated components and verify the circuits for resistance and continuity employing an ohmmeter.
