DTC P 0171/ 25 S ystem too L ean (Fuel Tri m )

CIRCUIT DESCRIPTION

Fuel trim refers to the feedback compensation value compared against the basic injection time. Fuel trim
includes short--term fuel trim and long--term fuel trim.
Short--term fuel trim is the short--term fuel compensation used to maintain the air--fuel ratio at its ideal
theoretical value. The signal from the heated oxygen sensor indicates whether the air--fuel ratio is RICH or
LEAN compared to the ideal theoretical value, triggering a reduction in fuel volume if the air--fuel ratio is rich,
and an increase in fuel volume if it is lean.
Long--term fuel trim is overall fuel compensation carried out long--term to compensate for continual deviation
of the short--term fuel trim form the central value due to individual engine differences, wear over time and
changes in the usage environment.
If both the short -- term fuel trim and long -- term fuel trim are LEAN or RICH beyond a certain value, it is de-
tected as a malfunction and the check engine warning (CHK ENG) lights up.

DTC No.

F) or more

(b) Engine speed: 1,500 rpm or more
(c) Vehicle speed: 100 km/h or less

S

HINT:

S

If the total of the short--term fuel trim value and long--term fuel trim value is within

±

25 %, the system

is functioning normally.

INSPECTION PROCEDURE

HINT:
Read freed frame data using hand--held tester. Because freeze frame records the engine conditions when
the malfunction is detected, when troubleshooting it is useful for determining whether the vehicle was run-
ning or stopped, the engine warmed up or not, the air--fuel ratio lean or rich, etc. at the time of the malfunction.

W hen using hand -- held tester

1 Check air induction system

(See page FI -- 1).

NG

Repair or replace.
