INSPECTION
1. INSPECT VVT SENSOR
a. Using an ohmmeter, measure the resistance between the terminals.
Resistance:
Cold: 835 to 1,400 Ohms
Hot: 1,060 to 1,645 Ohms
NOTE:
- "Cold" and "Hot" mean the temperature of the coils themselves.
- "Cold" is from -10 degree C (14 degree F) to 50 degree C (122 degree F) and "Hot" is from 50 degree C (122 degree F) to 100 degree C (212 degree F).
2. INSPECT CRANKSHAFT POSITION SENSOR
a. Using an ohmmeter, measure the resistance between the terminals.
Resistance:
Cold: 1,630 to 2,740 Ohms
Hot: 2,065 to 3,225 Ohms
NOTE:
- "Cold" and "Hot" mean the temperature of the coils themselves.
- "Cold" is from -10 degree C (14 degree F) to 50 degree C (122 degree F) and "Hot" is from 50 degree C (122 degree F) to 100 degree C (212 degree F).

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
