What happens to the p0115 coolant temperature sensor?
As the temperature of the coolant changes, the resistance changes on the ground signal to the PCM. When the engine is cold, the resistance is high. When the engine is warm, the resistance is low. If the PCM detects a voltage condition that seems abnormally low or high, P0115 will set. An example of an Engine Coolant Temperature ECT sensor
What happens when a Lexus trouble code is not cleared?
If the diagnostic trouble code is not cleared, it will be retained by the ECU and appear along with a new DTC in future trouble codes. If it is necessary to work on engine components requiring removal of the battery ground cable, confirm no DTC’s are stored.
What is the coolant sensor code on a Subaru Impreza?
Other coolant engine light codes: P0115, P0116, P0117, P0118, P0119, P0125, P0128 95 Subaru Impreza, auto transmission, 2.2 L engine. ODB Code P0115. Replaced ECT Sensor. Code returned.
When to suspect a coolant temperature circuit malfunction?
The wire should have no resistance, unplugged from the PCM to the sensor. If it does, repair open in the signal to the PCM. If it doesn’t have any resistance on the ground signal wire and the resistance test of the sensor is normal, then suspect a faulty PCM. Other coolant engine light codes: P0115, P0116, P0117, P0118, P0119, P0125, P0128
What does the ECT mean on a Lexus p0125?
The ECT is 0u0002C (32u0002F) at engine start. After 5 minutes running time, the ECT sensor still indicates that the engine is not warm enough to begin active feedback control of the air-fuel ratio. The ECM interprets this as a fault in the sensor or cooling system and sets a DTC.
If the diagnostic trouble code is not cleared, it will be retained by the ECU and appear along with a new DTC in future trouble codes. If it is necessary to work on engine components requiring removal of the battery ground cable, confirm no DTC’s are stored.
How much does it cost to repair a Lexus p0125?
Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. The cost of diagnosing the P0125 LEXUS code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle’s make and model, and even your engine type.
Where to find OBD1 code on Lexus SC300?
Transmission must be in Neutral position. All accessories must be turned Off. On pre-OBD II models, turn ignition to On, then use a jumper wire to connect terminals TE1 and El of the data link connector, located under the left hand side of the instrument panel. Codes are indicated by the number of flashes of the check engine warning light.
What happens if your coolant temperature sensor goes bad?
Fuel delivery, ignition timing and engine performance are among the key elements affected by the information the coolant temperature sensor gathers. If it goes bad, it can cause several problems. Signs Your Engine Coolant Temperature (ECT) Sensor Is Bad
Where is the coolant temperature sensor located in the engine?
Typically, the coolant temperature sensor is mounted in the engine block or cylinder head, near the thermostat or where the coolant flow is hottest. More than one coolant temperature sensor may be used on some systems to determine the temperature in different locations.
What is the error code for an engine coolant temperature sensor?
Error Code P0115 is described as an Engine Coolant Temperature (ECT) Sensor Circuit Malfunction.
What happens to p0115 when the coolant is warm?
As the temperature of the coolant changes, the resistance changes on the ground signal to the PCM. When the engine is cold, the resistance is high. When the engine is warm, the resistance is low. If the PCM detects a voltage condition that seems abnormally low or high, P0115 will set.

Is there a way to check coolant temperature?
(If you don’t have access to a scan tool, using the dash temperature gauge may not be an effective way to determine coolant temperature. This is because the P0115 code is referring to the ECT SENSOR, and the dash gauge is operated by, usually a one-wire SENDER. Basically a different sensor that the code doesn’t refer to.) 2.
As the temperature of the coolant changes, the resistance changes on the ground signal to the PCM. When the engine is cold, the resistance is high. When the engine is warm, the resistance is low.

What is the diagnostic code for insufficient coolant?
P0125 OBD-II Trouble Code: Insufficient Coolant Temperature for Closed Loop Fuel Control. Cost of diagnosing the P0125 code. P0125 is a diagnostic trouble code (DTC) for “Insufficient Coolant Temperature for Closed Loop Fuel Control”.
Where does the p0125 code come from on a Toyota?
SPECIAL NOTE: For some Toyota models, the P0125 code is set by the front O2 sensor. The service bulletin recommends replacing the O2 sensors to fix the problem.
What kind of check engine light is po125?
I reconnected them… My car developed with check engine light and faulty code was PO125, Toyota agents here replaced ECT sensor, 2 Oxygen sensors, but when I drove it naerly 10 kms, it came up again, Can you help me out to sort the issue….
