2013 Dodge Dart Transmission Range Sensor: P07xx Code Cost Breakdown

The 2013 Dodge Dart and the P07xx Code Dilemma

The 2013 Dodge Dart marked Fiat-Chrysler’s ambitious return to the compact sedan segment. While the platform offered engaging driving dynamics, its powertrain configurations—specifically the Aisin 6F24 6-speed automatic and the DDCT C635 dual-clutch transmission—introduced unique electronic vulnerabilities. One of the most frequent and frustrating issues owners face today is the illumination of the check engine light accompanied by a P07xx series diagnostic trouble code (DTC), pointing directly to the transmission range sensor (TRS).

As an automotive transmission specialist, I see these sensors fail due to heat cycling, moisture ingress, and internal resistor track degradation. When the Transmission Control Module (TCM) loses accurate gear position data, the vehicle may default to limp mode, refuse to crank, or experience harsh shift engagements. This comprehensive cost analysis and diagnostic guide breaks down exactly what you will pay to resolve a 2013 Dodge Dart transmission range sensor failure in 2026, alongside the technical data required to fix it right the first time.

Decoding the P07xx Matrix: What the TCM is Telling You

Before throwing parts at the vehicle, it is critical to understand the specific P07xx code your OBD-II scanner has pulled. The TRS on the Aisin 6F24 is essentially a multi-position resistor network. The TCM sends a 5-volt reference signal through the sensor, and the resistance changes based on the shift lever's physical detent.

• P0705 (Transmission Range Sensor Circuit Malfunction): The TCM detects an impossible or erratic voltage signal. This is the most common code and usually indicates internal sensor failure or a corroded connector.
• P0706 (Transmission Range Sensor Range/Performance): The signal is present but falls outside the expected parameters for a specific gear. Often caused by a misadjusted shift cable or a worn sensor wiper.
• P0707 (Transmission Range Sensor Circuit Low Input): The signal wire is shorted to ground, or the internal sensor resistance has dropped to near zero.
• P0708 (Transmission Range Sensor Circuit High Input): The signal wire is shorted to power, or there is an open circuit (broken wire) between the TRS and the TCM.

2026 Cost Analysis: Dealership vs. Independent vs. DIY

Repair costs have shifted significantly over the last few years due to supply chain adjustments and rising technician labor rates. Below is a realistic cost breakdown for replacing the transmission range sensor on a 2013 Dodge Dart equipped with the 2.0L or 2.4L Tigershark engine and the Aisin 6F24 automatic transmission.

Note: Dealerships typically charge a flat diagnostic fee of $140-$180, which is often waived if you proceed with the repair. Always confirm this policy before handing over your keys.

Where to Source Parts

For OEM replacements, the Mopar part number is typically 68224555AA (always verify with your VIN). You can find genuine OEM pricing via Mopar Parts Giant, which often undercuts local dealership parts counters by 15-20%. If you are on a budget, aftermarket options from Standard Motor Products (SMP) or Dorman are available through retailers like RockAuto for roughly $90. Avoid unbranded sensors from online auction sites; their internal resistor tracks are notorious for failing within 5,000 miles.

Crucial Diagnostic Step: TSBs and TCM Flashes

Before spending a dime on hard parts, you must rule out software anomalies. Early production 2013 Dodge Darts were subject to Technical Service Bulletins (TSBs) regarding false P0706 codes caused by aggressive TCM logic. According to data archived by the National Highway Traffic Safety Administration (NHTSA), certain build dates experienced range sensor codes not because the physical switch failed, but because the TCM misinterpreted voltage drops during rapid gear transitions.

The Fix: A dealership or shop with a WiTECH 2.0 diagnostic tool can flash the TCM with updated calibration software. This flash typically costs between $120 and $150. If the code returns immediately after the flash, the physical TRS is definitively faulty.

Multimeter Testing: Verify Before You Buy

Do not replace the sensor based on a code alone. Wiring harness chafing near the transmission bell housing is a known issue on the Dart. Here is the professional diagnostic workflow:

1. Locate the Connector: The TRS is mounted externally on the front/top of the 6F24 transmission case. Disconnect the 6-pin electrical connector.
2. Check the 5V Reference: With the ignition ON (engine OFF), use a digital multimeter to probe the harness side. You should see exactly 5.0V on the reference wire and a clean ground on the ground circuit.
3. Test the Sensor Body: Switch to continuity/resistance mode. Probe the sensor pins while manually moving the shift lever through the detents (P-R-N-D). The resistance should step up or down smoothly without any infinite (open) spikes. Any sudden drop to zero or infinity indicates a burned internal contact.

The DDCT C635 Caveat: 1.4L MultiAir Turbo Owners

If your 2013 Dart is equipped with the 1.4L MultiAir Turbo, you do not have the Aisin 6F24. You have the DDCT C635 Dual Dry Clutch Transmission. This transmission does not use a traditional, externally mounted mechanical range sensor. Instead, gear range is determined by a Hall-effect Shift Lever Module located inside the center console.

If a 1.4L Dart throws a P0705 code, the issue is almost always the interior shift lever assembly (Mopar Part #68168052AD) or a CAN-bus communication fault to the Mechatronic unit. The part cost for the shift lever assembly is significantly higher (roughly $320-$380), and the labor involves interior console teardown rather than under-hood mechanical work. Keep this distinction in mind when diagnosing or ordering parts.

Installation Procedure and Torque Specifications

For the 6F24 automatic, replacing the TRS is a straightforward job that requires basic hand tools, but precision is mandatory to avoid throwing a P0706 code immediately upon restart.

Step-by-Step Overview

1. Safety First: Disconnect the negative battery terminal to prevent accidental shorting of the 5V TCM reference circuit.
2. Clear Access: Remove the air intake resonator box to expose the top of the transmission and the shift cable bracket.
3. Detach Linkage: Remove the shift cable retaining nut from the TRS lever arm. Torque spec for reinstallation is 25 Nm (18 lb-ft).
4. Unbolt Sensor: Remove the two 10mm mounting bolts securing the TRS to the transmission case.
5. The Alignment Pin (Critical): Both the old and new TRS will have a small alignment hole. Before removing the old sensor, rotate it to the 'Neutral' position and insert a 4mm alignment pin (or drill bit) to lock the internal wiper. Insert the new sensor onto the shaft, keeping the pin in place until the mounting bolts are snug.
6. Torque Specs: The TRS mounting bolts must be torqued to 9 Nm (80 lb-in). Do not overtighten, as the plastic housing will crack and allow moisture to destroy the internal circuit board.
7. Relearn Procedure: Reconnect the battery. Turn the ignition to the RUN position (without starting) for 30 seconds to allow the TCM to map the new sensor's voltage boundaries. Cycle the shifter through all gears before starting the engine.

Final Thoughts on Drivetrain Electronics

The 2013 Dodge Dart transmission range sensor is a vital gateway between your physical gear selection and the TCM's electronic execution. While a P0705 or P0706 code can trigger immediate anxiety regarding catastrophic transmission failure, the reality is usually isolated to a $100 sensor or a software flash. By understanding the cost variables, verifying the wiring harness, and adhering to strict torque and alignment specifications, you can restore your Dart's shifting reliability without overpaying at the dealership.
