P1765 Chrysler Code - Transmission 12V Supply Relay Control Conditions
Quick Answer
The P1765 Chrysler diagnostic trouble code (DTC) relates to the transmission 12V supply relay control conditions. Common causes include Faulty 12V supply relay: A malfunctioning relay can disrupt the power supply to the transmission components, triggering the P1765 code, Wiring or connector damage: Corroded or damaged wiring connections can interfere with the relay's operation, leading to control conditions outside the norm, TCM malfunction: A faulty transmission control module may misinterpret sensor data or fail to communicate with the 12V supply relay properly. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P1765 Chrysler Description
The P1765 Chrysler diagnostic trouble code (DTC) relates to the transmission 12V supply relay control conditions. In vehicles equipped with automatic transmissions, the transmission control module (TCM) relies on various sensors and relays to operate efficiently. The 12V supply relay is responsible for providing power to critical components within the transmission system, ensuring smooth gear shifts and overall performance. When the TCM detects that the relay control conditions are outside the expected parameters, it triggers the P1765 code.
Common Causes of P1765 Chrysler
- Faulty 12V supply relay: A malfunctioning relay can disrupt the power supply to the transmission components, triggering the P1765 code.
- Wiring or connector damage: Corroded or damaged wiring connections can interfere with the relay's operation, leading to control conditions outside the norm.
- TCM malfunction: A faulty transmission control module may misinterpret sensor data or fail to communicate with the 12V supply relay properly.
- Transmission issues: Internal problems within the transmission, such as worn-out components or fluid contamination, can also contribute to the P1765 code.
Symptoms of P1765 Chrysler
- Erratic shifting: The vehicle may experience abrupt or delayed gear shifts, impacting the overall driving experience.
- Transmission slippage: The transmission may slip out of gear, causing a loss of power and acceleration.
- Harsh engagement: The transmission may engage with a jolt or jerk, potentially causing discomfort for passengers.
- Transmission warning light: The check engine light or transmission warning light may illuminate on the dashboard, signaling a potential issue with the transmission system.
How to Fix P1765 Chrysler
- Diagnostic scan: Use a diagnostic scanner to retrieve the specific fault codes stored in the vehicle's computer system, including the P1765 code.
- Relay inspection: Check the 12V supply relay for proper functioning, looking for signs of damage or wear that may warrant replacement.
- Wiring inspection: Inspect the wiring harness and connectors for any visible damage, corrosion, or loose connections that could affect the relay's operation.
- TCM testing: Test the transmission control module to ensure it is communicating effectively with the relay and other components within the transmission system.
- Repair or replacement: Depending on the findings from the diagnostic scan and inspections, repair or replace any faulty components, such as the relay, wiring, connectors, or TCM, to address the P1765 code and restore proper transmission function.
Cost to Fix P1765 Chrysler
The typical repair costs for addressing the P1765 Chrysler code may vary depending on the extent of the issue and the specific components requiring repair or replacement. On average, the cost of replacing a faulty 12V supply relay or repairing wiring/connectors may range from $150 to $300, including parts and labor. However, additional costs for TCM testing or replacement may increase the overall repair expenses. It's essential to consider the specific diagnosis time and labor rates at auto repair shops, which can vary based on factors such as location, vehicle make and model, and engine type. Auto repair shops commonly charge between $80 and $150 per hour for labor, but rates may differ at dealerships or independent shops. For a more accurate cost estimate, it's recommended to consult local repair facilities or obtain multiple quotes before proceeding with the repair.
