why does my Toyota Camry XV70 (2018-2024) struggle to start in cold weather

Solution

1. Preparation

• Tools Required: OBD-II scanner, multimeter, socket set, battery terminal cleaner, torque wrench.
• Ensure the vehicle is parked on a level surface, and the parking brake is engaged.

2. Battery Testing and Replacement

1. Test the Battery:
   • Use a multimeter to check the voltage; if it is below 12.4 volts, charge or replace the battery.
2. Clean Battery Terminals:
   • Disconnect the negative terminal first, followed by the positive. Clean corrosion using a battery terminal cleaner.
3. Reconnect Battery:
   • Reattach positive terminal first, then negative. Ensure they are tight (torque to manufacturer specifications if applicable).

3. Fuel System Inspection

1. Check Fuel Level:
   • Ensure the fuel tank has at least a quarter tank of fuel.
2. Test Fuel Pump:
   • Turn the ignition to the "ON" position without starting. Listen for the fuel pump activation sound; if silent, consider replacing the fuel pump.

4. Engine Oil and Starter Check

1. Inspect Engine Oil:
   • Check the oil level and viscosity; replace with oil rated for low temperatures if necessary.
2. Starter Motor Test:
   • Connect a multimeter to measure the current draw while cranking. If the draw exceeds specifications (typically between 100-200 amps), replace the starter motor.
