DTC P0101 (1.5 L Engine)
DTC P0101 : MAF Sensor Circuit Range/Performance Problem (Out of Range)
NOTE:
- Before you troubleshoot, review the general troubleshooting information .
- If DTC P2073, P2074, P2228, and/or P2229 are stored at the same time as DTC P0101, troubleshoot those DTCs first, then recheck for DTC P0101.

| P0101 MAF Sensor Circuit Range/Performance Problem |
DTC (PGM-FI)
- Parts condition check:
Check for poor connections or damage to these parts:
- PCV valve
- PCV hose
- Intake air duct
- Air cleaner
- Purge (PCS) line
- All parts through the turbocharger joint to the throttle body
Are the parts OK?
YES
Go to step 2.
NO
Repair or replace the damaged part (s).
- Intake air duct visual check
-1. Check for damage or looseness of the intake air duct in the air cleaner.
Is it OK?
YES
Go to step 3.
NO
Reconnect or replace the intake air duct in the air cleaner.
- Air cleaner element visual check
-1. Check for a dirty air cleaner element.
Is it dirty?
YES
Replace the air cleaner element .
NO
Go to step 4.
- MAF sensor signal check (without engine running)
-1. Turn the vehicle to the ON mode.
-2. Check the parameter (s) below with the HDS.
Signal Threshold Current conditions Values Unit Values Unit MAF SENSOR 520-10000 Hz Do the current condition (s) match the threshold?
YES
Go to step 5.
NO
- MAF sensor signal check (with engine running)
-1. Start the engine and let it idle.
-2. Check the parameter (s) below with the HDS.
Signal Threshold Current conditions Values Unit Values Unit MAF SENSOR 520-10000 Hz Do the current condition (s) match the threshold?
YES
Go to step 6.
NO
- Problem verification
-1. Turn the vehicle to the OFF (LOCK) mode.
-2. Turn the vehicle to the ON mode.
-3. Clear the DTC with the HDS.
-4. Start the engine. Hold the engine speed at 3, 000 rpm without load (in P or N) until the radiator fan comes on, then let it idle at least 5 seconds.
-5. Drive the vehicle at 37 mph (60 km/h) at least 5 seconds.
-6. Check for Pending or Confirmed DTCs with the HDS.
DTC Description Confirmed DTC Pending DTC P0101 MAF Sensor Circuit Range/Performance Problem Is DTC P0101 indicated?
YES
The failure is duplicated. Replace the MAF sensor/IAT sensor 1 .
NO
Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at the MAF sensor/IAT sensor 1 and the PCM. If the on-board snapshot of this DTC is recorded, try to reproduce the failure under the same conditions with the on-board snapshot .
