The knock control system adjusts the ignition timing to
minimize knock.
The MAP sensor converts manifold absolute pressure
into electrical signals to the ECM/PCM.
The vehicle has certain readiness codes that are part of
the on-board diagnostics for the emissions systems. If
the vehicle’s battery has been disconnected or gone
dead, if the DTCs have been cleared, or if the ECM/PCM
has been reset, these codes are reset. In some states,
part of the emissions testing is to make sure these
codes are set to complete. If all of them are not set to
complete, the vehicle may fail the test, or the test
cannot be finished.
To check if the readiness codes are set to complete,
turn the ignition switch to ON (II), but do not start the
engine. The MIL will come on for 15 20 seconds. If it
then goes off, the readiness codes are complete. If it
flashes five times, one or more readiness codes are not
complete. To set each code, drive the vehicle or run the
engine as described in the procedures (see page 11-69). The mass air flow (MAF) sensor/intake air temperature
(IAT) sensor contains a hot wire sensor, a cold wire
sensor, and a thermistor. It is located in the intake air
passage. The resistance of the hot wire sensor, the cold
wire sensor, and the thermistor change due to intake air
temperature and air flow. The control circuit in the MAF
sensor controls the current to keep the hot wire at a set
temperature. The current is converted to voltage in the
control circuit, then output to the ECM/PCM.
This sensor detects countershaft speed.

DTC Troubleshooting
MAF Sensor Circuit Range/
Performance Problem
NOTE:
 Before you troubleshoot, record all freeze data and any on-board snapshot, and review the general
troubleshooting information (see page 11-3).
 If DTC P1128, P1129, P2228, and/or P2229 are stored at the same time as DTC P0101, troubleshoot those
DTCs first, then recheck for DTC P0101.
1. Check for poor connections or damage to these parts:
 PCV hose
 Intake air duct
 Air cleaner
 Purge (PCS) line
 Brake booster
 Brake booster hose
Go to step 2.
Repair or replace the damaged part(s), then
go to step 17.
2. Check for damage or looseness at the air duct in the air cleaner.
Go to step 3.
Reconnect or replace the air duct in the air
cleaner, then go to step 15.
3. Check for a dirty air cleaner element.
Replace the air cleaner element (see page
11-346), then go to step 15.
Go to step 4. 4. Turn the ignition switch to LOCK (0).
5. Turn the ignition switch to ON (II).
6. Check the MAF SENSOR in the DATA LIST with the
HDS.
Go to step 7.
Go to step 13.
7. Start the engine.
8. Vary the engine speed between 2,000 rpm and 3,000 rpm.
9. Check the MAF SENSOR in the DATA LIST with the HDS.
Go to step 10.
Go to step 13.
10. Hold the engine speed at 3,000 rpm without load (A/T in P or N, M/T in neutral) until the radiator fan
comes on, then let it idle.
11. Test-drive the vehicle for several minutes in the range of these recorded freeze data parameters:
 ENGINE S PEED
 VSS
 MAP SENSOR
 MAF SENSOR
12. Monitor the OBD STATUS for DTC P0101 in the DTCs MENU with the HDS.
Go to step 13.
If the screen indicates PASSED, intermittent
failure, the system is OK at this time. Check for
poor connections or loose terminals at the MAF
sensor/IAT sensor and the ECM/PCM. If the screen
indicates NOT COMPLETED, go to step 11 and
recheck.

NOTE: Before you troubleshoot, record all freeze data
and any on-board snapshot, and review the general
troubleshooting information (see page 11-3).
1. Check for poor connections or loose terminals at ECT sensor 1, ECT sensor 2, and the IAT sensor.
Go to step 2.
Repair the connections or the terminals, then
go to step 15.
2. Remove the MAF sensor/IAT sensor (see page 11-224).
3. Allow the IAT sensor to cool to ambient temperature.
4. Note the ambient temperature.
5. Connect the MAF sensor/IAT sensor to its 5P connector, but do not install the sensor onto the air
cleaner.
6. Turn the ignition switch to ON (II).
7. Note the value of the IAT SENSOR quickly in the DATA LIST with the HDS.
8. Compare the value of IAT SENSOR and the ambient temperature.
Go to step 13.
Go to step 9.
9. Disconnect the MAF sensor/IAT sensor from its 5P connector.
10. Using a heat gun, blow hot air on the MAF sensor/ IAT sensor for a few seconds. Do not apply the heat
longer than a few seconds or you will damage the
sensor. 11. Connect the MAF sensor/IAT sensor to its 5P
connector, but do not install the sensor onto the air
cleaner.
12. ChecktheIATSENSORintheDATALISTwiththe HDS.
