This is my thoughts on the matter .. A cooler engine requires more fuel . So If your running a cooler thermostat or keeping the engine running cooler its going to call for some more fuel than an engine that is running at a higher temp.. Does your car have an adjustable fan or are you saying it has an adjustable temperature sensor ? thanks and holler if you need any more Jerry

How to repair P0125 for 2000 Mercury Mountaineer


P0125 OBD-II Trouble Code Technical Description Insufficient Coolant Temperature For Closed Loop Fuel Control What does that mean? 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. Symptoms You will likely not notice any drivability problems. Causes 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 Possible Solutions The simplest thing to do is to reset the code and see if it comes back. If the code comes back, the problem is likely going to be the result of the above causes (faulty thermostat, faulty ECT sensor, or a low coolant level).

03 trailblazer is hard to start I have to turn the key 15-20 times before it starts. I put in new fuel pump, filter, relays good starter good just hard to start any suggestions on how to fix this issue. ...


You can check the fuel pressure regulator ,
  1. Inspect for a fuel leak from the fuel pressure regulator vacuum port.
Is the fuel pressure regulator leaking fuel ?
This next test needs a scan tool with data reading capability's ,not a code reader ! Are you familiar with OBD 2 ? All the sensors , coolant , O2S , TPS , MAF , Intake air temp. etc. Sensor/System
Monitor the engine coolant temperature (ECT) sensor with the scan tool. Compare the engine coolant temperature with the ambient air temperature on a cold engine. If the coolant temperature reading is more than 5 degrees more or less than the ambient air temperature on a cold engine, check for high resistance in the coolant sensor circuit.
?€¢
Inspect the PCM grounds for being clean, tight, and in their proper location. Refer to Power and Grounding Component Views in Wiring Systems.


?€¢
Inspect vacuum hoses for splits, kinks, and proper connections, as shown on Vehicle Emission Control Information label. Inspect thoroughly for any type of leak or restriction.


?€¢
Inspect the air intake ducts for being collapsed, damaged areas, looseness, improper installation, or leaking, especially between the mass air flow (MAF) sensor and the throttle body.


?€¢
Inspect for air leaks at throttle body mounting area, mass air flow (MAF) sensor and intake manifold sealing surfaces.


?€¢
Inspect the wiring harness for poor connections, pinches, cuts, or other damage.


?€¢
Inspect for loose, damaged, or missing sensors and/or components.


Really need to check sensor PID'S with a scan tool, An maybe a scope too ! PID'S are parameter identification . All the sensors operate within a set voltage parameter , like the coolant temp. sensor an if it's off it can affect fuel delivery !

Check engine code P0125


PO125---- Insufficient Coolant Temperature for Closed Loop Fuel Control

No idea what car or engine you have

If you have a coolant temp sensor it could be bad

The thermostat also cool be stuck open

Both could be bad

Without the correct coolant temp (thermostat) or temp
sensor working, then your running the fuel injector timing
off Computer Controlled Open Loop-- meaning the oxygen
sensors are not in use as in closed loop & your wasting
gas ,as you have only a preset control over fuel trim eg:
no adjustment as you drive

I would install new spark plugs if over 3 years old -nothing
else,tune-ups are long gone 30 years ago,only the plugs left,
don't go done that road of being pitched something you don't need

I would new install front oxygen sensors,not the rear ones,
if over 100,000 miles
New thermostat & coolant temp sensor (CTS) if that
is what you have or other correction for that situtation.

P 1401 location


Codes don't have a certain location, a code means a problem has occurred in a system of the electronics of the cars fuel control or emission control system.
P1401 NISSAN - EGR Temperature SensorPossible causes- EGR Temperature Sensor harness is open or shorted
- EGR Temperature Sensor circuit poor electrical connection
- Faulty EGR Temperature Sensor
- Malfunction of EGR function, EGRC-BPT valve or EGRC-solenoid valve
- Blocked EGR passages When is the code detected?An excessively low voltage from the Exhaust Gas Recirculation (EGR) temperature sensor is sent to Engine Control Module (ECM) even when engine coolant temperature is low, or an excessively high voltage from the EGR temperature sensor is sent to ECM even when engine coolant temperature is high.
P1401 NISSAN Description The Exhaust Gas Recirculation (EGR) temperature sensor detects temperature changes in the EGR passage way. When the EGR valve opens, hot exhaust gases flow, and the temperature in the passage way changes. The EGR temperature sensor is a thermistor that modifies a voltage signal sent from the Engine Control Module (ECM). This modified signal then returns to the ECM as an input signal. As the temperature increases, EGR temperature sensor resistance decreases.
This sensor is not used to control the engine system. It is used only for the on board diagnosis

I want to know where the temperature coolant sensor is on a 96 oldsmobile aurora. If someone could send my a diagram or picture of where it is located.


I know there is one under the plastic intake manifold. You will have to remove it to get to the sensor though. I don't know if this one is for temp. gauge or fans or both?

Whenever I turned on the air condition in my Ford Explorer 2006, after few second the radiator Fan start running very frequently on high speed making noise. When the fan starts on high the rpm of the...


The cooling fan is supposed to come on when the /ac compressor clutch cycles on, and off when it cycles off.
The idle speed kicks up to compensate for the additional a/c compressor load and the additional alternator load. usually, just the low speed comes on until it hits a much higher temperature.

the system should cycle 4 to 7 times/minute at 79 degrees F.

Here are some things to consider:(The PCM (engine computer) is NEVER defective, don't replace it). I don't think it is the ECT (engine coolant temp sensor) or the Cylinder Head Temp Sensor. Or the VSS or the MAF sensors.


The electronically controlled fan clutch is controlled by the powertrain control module (PCM) based upon requests for airflow to cool the engine, transmission and A/C condenser. If no cooling is required, the electronics permit the fan to spin at a slower speed yielding improved fuel economy.
-------------------------------------------------------------------------------------------------------------------------------
Inoperative or damaged:
  • Electronically actuated fan clutch
  • Electronically actuated fan clutch controller
  • Wiring, connectors, relays or modules
  • Engine Coolant Temperature (ECT) sensor (4.0L SOHC)
  • Cylinder Head Temperature (CHT) sensor (4.6L [3V])
  • Mass Air Flow (MAF) sensor
  • Vehicle Speed Sensor (VSS)
  • ----------------------------------------------------------------------------
If the cause is not visually evident, connect the scan tool to the Data Link Connector (DLC).
Retrieve any DTC Codes (Diagnostic Test Code). Autozone will do for free.

--------------------------------------------------------------

The cooling fan clutch actuator valve controls the fluid flow from the reservoir into the working chamber. Once viscous fluid is in the working chamber, shearing of the fluid results in fan rotation.

The cooling fan clutch actuator valve is activated with a pulse width modulated (PWM) output signal from the powertrain control module (PCM). By opening and closing the fluid port valve, the PCM can control the cooling fan clutch speed. The cooling fan clutch speed is measured by a Hall-effect sensor and is monitored by the PCM during closed loop operation.

The PCM optimizes fan speed based on engine coolant temperature (ECT), engine oil temperature (EOT), transmission fluid temperature (TFT), intake air temperature (IAT), or air conditioning requirements. When an increased demand for fan speed is requested for vehicle cooling, the PCM monitors the fan speed through the Hall-effect sensor. If a fan speed increase is required, the PCM outputs the PWM signal to the fluid port, providing the required fan speed increase.

Wont start when cold out


If your vehicle is fuel injected the problem you describe could be result of a few different things: 1) Check your Idle Air Control (IAC) sensor/motor. This sensor is located on your vehicles, throttle body. The purpose of this sensor is to control the car's idle under various operating conditions including ambiant temperature. In order for it to function correctly, the internal components must be clean (meaning, little or no carbon build up) and it must be undamaged. Sometimes the IAC can be cleaned; however, if this cleaning procedure is not properly done, the IAC can become damaged. This sensor is also sometimes called the "Cold Start" sensor. A new IAC will cost $50-$100. 2) Check you Coolant Temperature sensor. This senso is located on the top of your engine and is screwed into your intake manifold. When this fails your car will experience starting problems when cold outside. A new Coolant Temp sensor will cost about $100. Take a look at two three solutions first. My guess is your IAC needs to be cleaned or replaced. Good Luck!

Please remember to rate this solution. Thanks!
