DESCRIPTION
This in-Range Self-Test was designed to detect in-range failures of the Mass Air Flow (MAF) sensor, Throttle Position (TP) sensor or the fuel delivery system. The Powertrain Control Module (PCM) will use information from these three areas based on vehicle load to generate three independent values. The three independent values will be continuously monitored by the PCM and if one of the values differs significantly from the others during normal vehicle operation, a Continuous Memory Diagnostic Trouble Code (DTC) will be displayed.
NOTE
You should enter this Pinpoint Test only when you have been directed here from Diagnostic Routines.
REMEMBER:
To prevent the replacement of good components, be aware that the following non-Electronic Engine Controls (EEC) areas may be at fault:
- Excessive blow-by
- Fuel pressure
- PCV malfunction
- Throttle sticking or linkage binding
- Vacuum leaks
- Idle Air Control Solenoid
This Pinpoint Test is intended to diagnose only the following:
- TP sensor
- MAF sensor
- Intake Air Temperature (IAT) sensor
- Fuel injectors

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.
