What does Insufficient coolant temperature for closed loop fuel control mean?
P0126 means “Insufficient Coolant Temperature for Stable Operation,” while P0128 means “Engine Coolant Temperature Below Thermostat Regulating Temperature.” If the P0125 occurs with one of these, you’ll need to look up their causes and symptoms so you can determine the cause of this engine problem more efficiently.
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.
What to do if your thermostat has a p0125 code?
To address the P0125 code follow these steps in diagnosis and repair: Connect a professional scan tool and verify that the code exists Check for any other faults and clear the code to see if it returns Analyze the data from the ECM Verify the coolant level Determine that the thermostat is opening properly
What happens when the engine is not warm enough for closed loop fuel control?
The Engine Control Module (ECM) monitors the ECT signal voltage after engine start-up. If, after sufficient time has passed, the sensor still reports that the engine is not warm enough for closed-loop fuel control, the ECM interprets this as a fault in the sensor or cooling system and sets a Detected Trouble Code (DTC).
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.
