P0706 on 2009-2020 Dodge Journey: Transmission Range Sensor Causes and Fixes

What's Unique About the 2009-2020 Dodge Journey

The Dodge Journey, particularly those with the common 6-speed 62TE automatic transmission, has a known point of failure with the Transmission Range Sensor (TRS). Unlike many other vehicles where this sensor is mounted externally, on the 62TE it is an integral part of the solenoid/pressure switch assembly, located inside the transmission and attached to the valve body. This internal placement makes replacement more labor-intensive, as the transmission pan and valve body must be removed to access it. The sensor is not always sold separately from the entire solenoid pack, which increases repair cost.

Symptoms You May Notice

• Check Engine Light is on
• Vehicle may be stuck in 'limp mode' (usually 2nd or 3rd gear)
• Harsh or delayed shifting
• Incorrect gear selection displayed on the dashboard (e.g., shows 'R' when in 'D')
• PRNDL indicator on the dash may flash or be blank
• Engine will not start
• Vehicle starts in a gear other than Park or Neutral
• Reverse lights may not illuminate
• On startup, reverse camera may activate even when not in reverse

Most Likely Causes

1. Faulty Transmission Range Sensor (TRS) / Solenoid Pack 🔴 High Probability → Shop Transmission Assembly The sensor is a common failure item on the 62TE transmission due to age and wear. Being internal, it is subjected to constant heat and fluid exposure. The TRS is integrated into the solenoid pack, which is a known weak point on these transmissions. Failures are common between 80,000 and 120,000 miles, often due to fluid contamination clogging small passages.
   How to confirm: A technician will use a scan tool to monitor the sensor's data stream (PRNDL state) while shifting through the gears. If the readings are erratic, incorrect, or don't change, the sensor is likely bad. The diagnostic procedure involves checking for metal debris on the sensor's code plate. Resistance checks can be performed at the transmission connector.
   Typical fix: Replace the Transmission Solenoid/TRS Assembly. This involves draining the fluid, dropping the transmission pan, and removing the valve body to access the part. The entire solenoid pack is often replaced as a unit.
   Est. part cost: $150-$400
2. Damaged Wiring or Corroded Connector 🟡 Medium Probability The main transmission electrical connector (a round, 23-pin connector) is exposed to the elements under the vehicle, making it susceptible to corrosion, moisture intrusion, or physical damage. Fluid can also leak from the connector seal.
   How to confirm: Visually inspect the main electrical connector at the transmission for corrosion (green tinge), bent pins, or damaged wires. Perform a continuity and voltage test on the sensor circuit wires between the connector and the PCM. Check for fluid wicking up the harness.
   Typical fix: Clean the connector terminals with an electrical contact cleaner and a soft brush, apply dielectric grease, and ensure the seal is intact. If the wiring is damaged, it will need to be repaired or replaced. A leaking connector seal should be replaced.
   Est. part cost: $5-$50
3. Low or Dirty Transmission Fluid ⚪ Low Probability → Shop Transmission Assembly Neglected maintenance can lead to fluid that is contaminated with clutch material and metal shavings, which can interfere with the operation of internal components, including the valve body and sensors. Using fluid other than the specified Mopar ATF+4 can also cause issues.
   How to confirm: Check the level and condition of the transmission fluid using the dipstick (if equipped) or via the service procedure. If it is dark, burnt-smelling, or contains debris, it needs to be changed.
   Typical fix: Perform a transmission fluid and filter change. This is often done as part of the TRS replacement since the pan must be removed anyway.
   Est. part cost: $80-$150

Rare But Worth Checking

• Faulty Powertrain Control Module (PCM): This is very rare. The PCM should only be considered after all other possibilities, including the sensor, solenoid pack, and wiring, have been thoroughly tested and ruled out.
• Misadjusted or Damaged Shift Lever Cable: If the cable connecting the gear shifter to the transmission is stretched or damaged, it can cause a mismatch between the selected gear and what the sensor reports. This is less common than sensor failure but worth checking, especially if the shifter feels loose.

Diagnosis Steps

1. Scan the vehicle for all stored trouble codes. Note if P0700 is present with P0706.
2. Using a professional scan tool, view the live data for the Transmission Range Sensor (PRNDL state). Observe the reading as you move the shifter through all gears (P, R, N, D, L).
3. If the data is erratic, missing, or doesn't match the gear position, the sensor/solenoid pack is the primary suspect.
4. Turn the ignition off. Locate and inspect the main transmission wiring harness connector for any signs of corrosion, moisture, or damage. Clean and secure the connection.
5. Check the transmission fluid level and condition. Low or dirty fluid can cause a variety of issues. Ensure Mopar ATF+4 is used.
6. If the sensor data is stable but incorrect, check the adjustment of the shift cable at the transmission manual lever.
7. If external wiring and fluid are good, the next step is internal inspection, which involves removing the transmission pan and valve body to access the solenoid/TRS assembly. Check for metal debris on the assembly.
8. If the sensor and wiring test good, the issue may be with the PCM, but this is the least likely cause.

Used vs. New Parts: Buying Guide for This Vehicle

When a used part is the smart pick: Given the high failure rate of the 62TE solenoid pack and the significant labor involved in replacement, using a used part from a junkyard is generally NOT recommended. The risk of installing a part that is already near the end of its service life is very high.

Donor-vehicle mileage cap: roughly under 60000 miles for the part to have meaningful remaining life.

What to inspect on the donor part:

• Verify the donor vehicle's mileage; lower is always better.
• Inspect the transmission fluid from the donor vehicle if possible. If it is dark, burnt, or full of debris, avoid the part.
• Check the main electrical connector pins for any signs of corrosion, damage, or fluid intrusion.

OEM-only on this vehicle (don't cheap out):

• Transmission Solenoid/Range Sensor Assembly

Aftermarket brands forum-validated for this vehicle:

• Mopar (OEM)

Brands owners have reported issues with on this vehicle:

• Unbranded or generic 'white box' solenoid packs from online marketplaces are a significant gamble. While brands like Dorman and Standard Motor Products are generally reputable, for this specific high-failure, high-labor part, sticking with the OEM Mopar unit is the safest investment to avoid repeat repairs.
