Freeze Frame Data
2001 Chevrolet Monte Carlo V6-3.4L VIN ESECTION Freeze Frame Data
Government regulations require that engine operating conditions be captured whenever the MIL is illuminated. The data captured is called Freeze Frame data. The Freeze Frame data is very similar to a single record of operating conditions. Whenever the MIL is illuminated, the corresponding record of operating conditions is recorded as Freeze Frame data. A subsequent failure will not update the recorded operating conditions.
The Freeze Frame data parameters stored with a DTC failure include the following:
^ The air/fuel ratio
^ The air flow rate
^ The fuel trim
^ The engine speed
^ The engine load
^ The engine coolant temperature
^ The vehicle speed
^ The Throttle Position (TP) angle
^ The Manifold Absolute Pressure (MAP)/Barometric Pressure (BARO)
^ The injector base pulse width
^ The loop status
Freeze Frame data can only be overwritten with data associated with a misfire or fuel trim malfunction. Data from these faults take precedence over data associated with any other fault. The Freeze Frame data will not be erased unless the associated history DTC is cleared.

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.
