DTC P0100 MASS AIR FLOW CIRCUIT MALFUNCTION
CIRCUIT DESCRIPTION
The mass air flow meter uses a platinum hot wire. The hot wire air flow meter consists of a platinum hot wire,
temprature sensor and a control circuit installed in a plastic housing. The hot wire air flow meter works on
the principle that the hot wire and temprature sensor located in the intake air bypass of the housing detect
any changes in the intake air temperature.
The hot wire is maintained at the set temperature by controlling the current flow through the hot wire. This
current flow is then measured as the output voltage of the mass air flow meter.
The circuit is constructed so that the platinum hot wire and temprature sensor provide a bridge circuit, with
the power transistor controlled so that the potential of A and B remains equal to maintain the set temperature.

INSPECTION PROCEDURE
HINT:
Read freeze frame data using \f \b\f\f
Freeze frame data records the engine conditions when
a malfunction is detected. When troubleshooting, it is useful for determi\
ning whether the vehicle was running
or stopped, the engine was warmed up or not, the air±fuel ratio was lea\
n or rich, etc. at the time of the mal-
function.
1READ VALUE OF HAND±HELD TESTER(MASS AIR FLOW RATE)
(a)Connect the hand±held tester to the DLC3.
(b)Start the engine.
(c)Read air flow rate on the hand±held tester.
(d)Select the item ºDIAGNOSIS / OBD/MOBD / DATA LIST / ALL / MAFº and read its value displayed on the hand±held tester.
Result:
Air flow rate (gm/sec)Proceed to
