This summary uses the existing diagnostic information shown in full below.
This code means there's a problem with the car's gas pedal sensor or the engine's thermostat. It's like when the car can't tell how much you're pressing the gas pedal or if the engine isn't getting warm enough.
The code P1624 is related to an issue with the pedal position sensor or the coolant thermostat. The pedal position sensor helps the car understand how much the accelerator pedal is pressed, while the thermostat ensures the engine reaches the correct temperature.
P1624 indicates a malfunction in the pedal position sensor's potentiometer supply channel, which may affect the vehicle's ability to accurately read the accelerator pedal position. Additionally, it can indicate that the engine's coolant temperature is below the thermostat's regulating temperature, suggesting a potential issue with the thermostat not closing properly.
• Check Engine Light is on
• Poor engine performance
• Engine takes longer to warm up
• Faulty pedal position sensor
• Wiring issues in the sensor circuit
• Stuck open coolant thermostat
Potentiometer: A variable resistor used to measure position or angle.
Thermostat: A device that regulates the flow of coolant to maintain engine temperature.
• Use an OBD-II scanner to confirm the code
• Inspect the pedal position sensor and its wiring
• Check the thermostat for proper operation
• Replace the pedal position sensor if faulty
• Repair or replace damaged wiring
• Replace the thermostat if it's stuck open
• OBD-II scanner
• Multimeter
• Wrench set

Moderate
• BMW 3 Series
• Hyundai Sonata
• Kia Optima
• Regular maintenance checks
• Ensure proper coolant levels
• Inspect sensors periodically
Sensor Issue
• Avoid hard acceleration until repaired
• Monitor coolant temperature gauge
Check with the vehicle manufacturer for warranty coverage on sensors and thermostats.
This code has been reported in vehicles with aging sensors or thermostats, often due to wear and tear.
Moderate – While the vehicle may still be drivable, it should be repaired to avoid further issues.
Driving with a malfunctioning sensor or thermostat can lead to reduced performance and increased emissions.
• Engine at operating temperature
• Vehicle stationary with ignition on
The pedal position sensor is located near the accelerator pedal, while the thermostat is typically located near the engine block.
Q: Can I drive with a P1624 code?
A: It's possible to drive, but it's recommended to fix the issue to avoid further problems.
Q: How can I reset the P1624 code?
A: You can clear the code with an OBD-II scanner, but it's important to fix the underlying issue first.

Fitment Required · Vehicle-fitment part
Relevant when coolant-temperature and warm-up faults indicate a thermostat-related issue.
Coolant-temperature and warm-up faults often lead to thermostat testing and replacement.
Thermostats are vehicle-specific and should be matched by engine and housing style.
