P1545 Mitsubishi Code - DOR Radiator Tampering Monitor Temp Change After Thermostat Open
Quick Answer
The P1545 diagnostic trouble code (DTC) for Mitsubishi vehicles specifically relates to the DOR (Dynamic Onboard Radial) Radiator Tampering Monitor and indicates a temperature change after the thermostat opens. Common causes include Faulty Thermostat: A malfunctioning thermostat can cause improper coolant flow, leading to temperature fluctuations, Low Coolant Level: Insufficient coolant in the system can affect the cooling process and trigger the code, Cooling System Leak: A leak in the cooling system can disrupt the proper flow of coolant, causing temperature changes. 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 P1545 Mitsubishi Description
The P1545 diagnostic trouble code (DTC) for Mitsubishi vehicles specifically relates to the DOR (Dynamic Onboard Radial) Radiator Tampering Monitor and indicates a temperature change after the thermostat opens. This code is typically triggered when there is a discrepancy in the coolant temperature observed by the engine control module (ECM) compared to what is expected after the thermostat opens. The ECM continuously monitors the coolant temperature to ensure optimal engine performance and efficiency.
Common Causes of P1545 Mitsubishi
- Faulty Thermostat: A malfunctioning thermostat can cause improper coolant flow, leading to temperature fluctuations.
- Low Coolant Level: Insufficient coolant in the system can affect the cooling process and trigger the code.
- Cooling System Leak: A leak in the cooling system can disrupt the proper flow of coolant, causing temperature changes.
- Radiator Issues: Problems with the radiator, such as clogs or damage, can impact the cooling system's efficiency.
- ECM Malfunction: In rare cases, a malfunction in the engine control module can lead to erroneous temperature readings.
Symptoms of P1545 Mitsubishi
- Overheating: The engine may run hotter than normal, potentially leading to overheating.
- Poor Fuel Efficiency: A malfunction in the cooling system can impact the engine's efficiency, resulting in decreased fuel economy.
- Check Engine Light: The P1545 code will trigger the check engine light on the dashboard.
- Reduced Performance: The vehicle may experience a decrease in performance due to improper engine cooling.
- Engine Stalling: In severe cases, the engine may stall due to overheating issues.
How to Fix P1545 Mitsubishi
- Check Coolant Level: Ensure the coolant level is at the appropriate level and top up if necessary.
- Test Thermostat: Inspect and test the thermostat to determine if it is functioning correctly.
- Check Radiator: Inspect the radiator for any clogs, leaks, or damage, and address any issues found.
- Clear Fault Codes: Use a diagnostic scanner to clear the P1545 code and reset the ECM.
- Monitor Temperature: Monitor the coolant temperature after repairs to ensure the issue has been resolved.
Cost to Fix P1545 Mitsubishi
The cost of repairing a P1545 code can vary depending on the specific cause of the issue. On average, the repair costs for this type of problem can range from $200 to $500, including parts and labor. Keep in mind that diagnostic time and labor rates can vary between auto repair shops, so it's recommended to obtain quotes from multiple sources to get an accurate estimate. Additionally, the cost may be higher if components such as the thermostat or radiator need to be replaced.
