Hyundai Santa Fe (2006 year). Manual — part 524
FLA -162
FUEL SYSTEM
1)
Connect scantool and IG "ON".
2)
Select "OCV" on the Actuation Test.
3)
Activate "OCV" by pressing "STRT(F1)" key.
(should hear a faint click from Oil Control solenoid Valve)
4)
Repeat this procedure 4 or 5 times to ensure reliability
EGRF602M
5)
Does OCV generate click sound during acutation test ?
YES
▶ Substitute with a known - good PCM and check for proper operation. If the problem is corrected, replace PCM
and go to "Verification of Vehicle Repair" procedure.
NOTE
There is a memory reset function on scantool that can erase optional parts automatically detected and memorized
by PCM.
Before or after testing PCM on the vehicle, use this function to reuse the PCM on the others
NO
▶ Substitute with a known - good OCV and check for proper operation. If the problem is corrected, replace OCV
and go to "Verification of Vehicle Repair" procedure.
VERIFICATION OF VEHICLE REPAIR

DTC P0101 MASS OR VOLUME AIR FLOW CIRCUIT

GENERAL DESCRIPTION
E1F15262
The Mass Air Flow Sensor (MAFS) is located between the air cleaner assembly and the throttle body. The MAFS uses
a hot film type sensing element to measure the mass of intake air entering the engine. This hot film type air flow sensor
consists of a hot film sensor, housing and metering ducts. Mass air flow rate is measured by detection of heat transfer
from a hot film probe. The change in air flow rate causes change in the amount of heat being transferred from the hot
film probe surface to the air. A large amount of intake air represents acceleration or high load conditions while a small
amount of intake air represents deceleration or idle. The mass of intake air should increase at acceleration and be stable
during constant engine speed. The ECM uses this information to determine the injection duration and ignition timing for
the desired air/fuel ratio.
DTC DESCRIPTION
E06B8990
The difference between values coming from the MAF Sensor and those are calculated is analyzed. This difference, or
error, is then compared to high and low limit calibration values, which are functions of engine speed. PCM compares
MAFS output to calculated flow rate value while enable condition is met.
If the actual air flow is higher than Maximum threshold, or lower than Minimum threshold for more than 75 seconds failure
for every 125 seconds test. PCM determines that a fault exists and a DTC is stored.
