P0711 on 2015 Chrysler 200: Transmission Temp Sensor Causes & Fixes

What's Unique About the 2015-2015 Chrysler 200

The 2015 Chrysler 200 was one of the first vehicles to heavily feature the ZF 9-speed automatic transmission (specifically the 948TE, also known as DFH 🎬 Watch: A technical introduction to the 948TE transmission system. for FWD models, or the 9HP48/DF5 for AWD V6 models). Early production models were known for significant software-related drivability issues, leading to widespread customer complaints. In response, Chrysler issued multiple Technical Service Bulletins (TSBs) to update the Transmission Control Module (TCM) software. Code P0711 is a frequently cited DTC in these bulletins, indicating that the problem is often not a failed hardware part, but a software calibration issue that needs to be corrected with a reflash.

Most Likely Causes

1. Outdated Transmission Control Module (TCM) Software 🔴 High Probability → Shop Transmission Assembly Early versions of the 9-speed transmission software had calibration issues. Chrysler released multiple TSBs to correct this specific code via a software update. [TSB #21-019-17 REV. A, TSB #21-021-15 REV-C, TSB #21-015-16]
   How to confirm: A dealer or qualified shop must check the current software version against the latest available updates for the vehicle's VIN using a wiTECH scan tool.
   Typical fix: Reprogramming (flashing) the TCM with the latest manufacturer software. This is often referred to as a 'Flash' in the TSBs.
   Est. part cost: $0
2. Faulty Transmission Fluid Temperature (TFT) Sensor / Internal Harness 🟡 Medium Probability → Shop Transmission Assembly The temperature sensor is integrated into the transmission's internal wiring harness (also called a lead frame). This complete assembly can fail, causing erratic readings. This is the next logical step after a software update fails to fix the issue.
   How to confirm: After a software update fails to fix the code, a technician can monitor the live sensor data with a scan tool. If the temperature readings are erratic, stuck at a single value (e.g., -40°F), or jump to illogical values, the sensor/harness is faulty. Resistance can be checked with a multimeter and compared to specifications.
   Typical fix: The transmission pan must be removed to replace the internal wiring harness assembly. This is a labor-intensive job. 🎬 Watch: How to test and replace the fluid temperature sensor.
   Est. part cost: $200-$400
3. Damaged Wiring or Corroded Connectors ⚪ Low Probability
   How to confirm: Visually inspect the external transmission wiring harness and main connector for damage, corrosion, or loose pins. A multimeter can be used to check for continuity between the TCM and the transmission connector.
   Typical fix: Repairing the damaged section of the harness or cleaning/replacing the connector.
   Est. part cost: $10-$100
4. Low or Degraded Transmission Fluid ⚪ Low Probability → Shop Transmission Assembly
   How to confirm: Check the transmission fluid level and condition according to the manufacturer's procedure. The fluid should be at the correct level and not appear dark, burnt, or contain debris.
   Typical fix: Perform a transmission fluid drain and fill or flush with the correct specification fluid (Mopar ZF 8&9 Speed ATF or equivalent).
   Est. part cost: $150-$300

Rare But Worth Checking

• Failing Transmission Control Module (TCM): → Shop Transmission Assembly While rare, the TCM itself can fail internally. This should only be considered after all other possibilities, including software, sensor, and wiring, have been exhaustively eliminated.

Diagnosis Steps

1. Connect an OBD-II scanner to verify the P0711 code and check for any other related DTCs.
2. Check for applicable Technical Service Bulletins (TSBs) for your vehicle's VIN. For a 2015 Chrysler 200, TSBs #21-019-17 REV. A, #21-021-15 REV-C, and #21-015-16 are highly relevant.
3. If a software update is available, have a dealership or qualified shop perform the TCM reflash. This is the most probable solution and the first step mandated by the manufacturer.
4. Clear the codes and perform a thorough test drive, including the conditions mentioned in the TSBs (e.g., driving on grades). If the code does not return, the issue is resolved.
5. If the code returns, use a scan tool to monitor live data. On a cold start, compare the Transmission Fluid Temperature (TFT) to the Engine Coolant Temperature (ECT) and Intake Air Temperature (IAT). They should be within 5-10 degrees of each other.
6. Watch the TFT reading as the vehicle warms up. It should climb steadily. If it's stuck, erratic, or doesn't change, the sensor is likely faulty.
7. Inspect the main transmission electrical connector and wiring harness for any signs of physical damage, corrosion, or moisture.
8. If the external wiring is intact, test the sensor circuit resistance at the TCM connector across pins 10 (YEL/VIO) and 12 (YEL/WHT). Compare readings to a temperature/resistance chart.
9. If the sensor readings are still faulty, the problem is internal to the transmission. The next step is to drop the transmission pan and replace the sensor/harness assembly.

Mechanic-Grade Diagnostic Values

• Transmission Fluid Temperature Sensor Resistance — expected: Approx. 6,455 Ohms at 10°C (50°F); Approx. 44,000 Ohms at -30°C (-22°F). Resistance decreases as temperature increases.. Failure: An open circuit (infinite resistance) or a reading that does not change with temperature.
• Solenoid Resistance (Clutches B, C, D, E, TCC, Control Pressure) — expected: 5.3 - 5.6 Ohms. Failure: Resistance significantly outside this range indicates a faulty solenoid.
• Solenoid Resistance (Dog Clutches A & F) — expected: 10.6 Ohms. Failure: Resistance significantly outside this range indicates a faulty solenoid.
• TCM Sensor Reference Voltage — expected: ~5 Volts. Failure: No voltage present at the sensor connector (with sensor unplugged, key on) may indicate a wiring or TCM fault.

Scan Tool Commands That Help

• wiTECH: PROXI Configuration Alignment — After reprogramming or replacing a module (like the TCM) to ensure all vehicle modules are synchronized with the correct VIN and configuration. Failure to do this can cause communication errors.
• wiTECH: TCM VIN Verification — Used as part of the module replacement/reprogramming process to write the vehicle's VIN into the new or updated TCM.
• Miller tool #8333 (Transmission Simulator): Thermistor Voltage Switch — For advanced diagnosis, this special tool connects in place of the transmission harness to send known-good voltage signals to the PCM/TCM, verifying the integrity of the control module and wiring independently of the internal transmission components.

Wiring & Ground Locations

• TCM Connector C1, Pin 10 — At the Transmission Control Module, which is integrated into the Powertrain Control Module (PCM) on the right side of the engine bay near the battery.. This is the 'TRANSMISSION TEMPERATURE SIGNAL' wire (Yellow/Violet). It carries the voltage signal from the sensor back to the control module.
• TCM Connector C1, Pin 12 — At the Transmission Control Module (PCM).. This is the 'SENSOR GROUND' wire (Yellow/White). A fault in the ground circuit can cause incorrect sensor readings.
• G909A / G905A — Primary chassis ground points located in the engine compartment, often on the frame rail or below the headlight area.. A poor main ground can cause floating voltages and widespread electrical issues, potentially triggering sensor performance codes even if the sensor and its dedicated wiring are good.
