DTC Parameters

• Vehicle speed is zero MPH.
• TP angle is zero percent.
• BARO is greater than 70 kPa.
• Ignition voltage is 9-18 volts.
• IAT is greater than -13°F (-25°C).
• Desired idle speed is 650-875 RPM.
• ECT is greater than 140°F (60°C).
• No ECT, EGR pintle, MAP, misfire, vehicle speed or TP sensor DTCs are set.
