This means that the engine coolant temperature (ECT) sensor indicates that the engine has not reached the required temperature level to enter closed-loop operation within a specified amount of time after starting the engine.
бавно е загрял (щом е работил на място).
A code P0125 may mean that one or more of the following has happened:
Insufficient warm up time
Low engine coolant level
Leaking or stuck open thermostat
Faulty coolant temperature sensor
prichini za P0125 za tazi kola(direkno izvadeno ot Repair Manual-a za 97 Lexus ES300):
Open or short in heated oxygen sensor (bank 1, 2 sensor 1) circuit
Heated oxygen sensor (bank 1, 2 sensor 1)
DTC Detecting Condition:
After the engine is warmed up, heated oxygen sensor (bank 1,
2 sensor 1) output does not indicate RICH even once when
conditions (a), (b), (c) and (d) continue for at least 2 min.:
(a) Engine speed: 1,500 rpm or more
(b) Vehicle speed: 40 ∼ 100 km/h (25 ∼ 62 mph)
(c) Throttle valve does not fully closed
(d) 140 sec. or more after starting engine
INSPECTION PROCEDURE:
1. Connect OBD II scan tool or LEXUS hand−held tester and read value for voltage output of heated oxygen sensor (bank 1, 2 sensor 1).
PREPARATION:
(a) Connect the OBD II scan tool or LEXUS hand−held tester to the DLC3.
(b) Warm up engine to normal operating temp.
CHECK:
Read voltage output of heated oxygen sensor (bank 1 sensor 1) when engine is suddenly raced.
HINT:Perform quick racing to 4,000 rpm 3 times using accelerator pedal.
OK:
Both heated oxygen sensors [(bank 1 sensor 1) (bank 2 sensor 1)] output a RICH signal
(0.45 V or more) at least once.
if OK -> Check and replace ECM (See page IN−27).
if NG -> step 2
2. Check for open and short in harness and connector between ECM and heated oxygen sensor (bank 1, 2 sensor 1) (See page IN−27).
if OK -> Replace heated oxygen sensor (bank 1, 2 sensor 1).
if NG -> Repair or replace harness or connector.
