Question about 1999 Chevrolet S-10 Pickup

How do i reset the computer after a repair has been made?

I recently change the temperature control sensor, but now i need to reset the computer so it no longer reads bad. i tried the old fashioned way of disconnecting the battery for a few minutes but this did nothing. the change oil light is on as well so i imagine if the computer was reset then this would no longer read too. can some one please help me with this?

    thank you for this informative info as this was indeed true. the only way to clear these codes was to have them cleared with a scanner. many people continued to tell me clearing the codes could be done by disconnecting the battery for a longer period, but this was FALSE.

The only way to clear codes on your vehicle is to have a scan tool that finds and removes codes. You can buy one and it will pay for itself by the second or third time you use it. Good luck

Check engine lite 2002 mercury mountaineer

Did you do a complete OBD code-clear of the computer?
Codes don't reset just because you fix the problem. Many of the codes need to be cleared using a OBD machine - buy it at Auto repair places for about $60. You also have to disconnect the battery for a minute to reset some of the codes.
If the codes don't come back, you are good. If they reset again, you still have a problem.

P1114 vw passat

DTC P1114Circuit Description

The engine coolant temperature (ECT) sensor is a variable resistor, that measures the temperature of the engine coolant. The powertrain control module (PCM) supplies 5 volts to the ECT signal circuit and a ground for the ECT low reference circuit. When the ECT is cold, the sensor resistance is high. When the ECT increases, the sensor resistance lowers. With high sensor resistance, the PCM detects a high voltage on the ECT signal circuit. With lower sensor resistance, the PCM detects a lower voltage on the ECT signal circuit. If the PCM detects an excessively low ECT signal voltage, which is a high temperature indication, DTC P1114 sets.
Conditions for Running the DTC

The engine run time is more than 5 seconds.
Conditions for Setting the DTC

The PCM detects an intermittent high ECT sensor temperature while the engine is running, and the run time exceeds 5 seconds.

Code 1 senser P0118 on a 2004 V.W beetle dicesel

P0118 for Volkswagen - (ECT) Engine Colant Temperature Circuit High

Symptoms:- Engine Light ON (or Service Engine Soon Warning Light)

Possible causes:
(Inspect the following... Repair/Replace if necessary)
- Low engine coolant level
- Engine Coolant Temperature (ECT) sensor harness is open or shorted
- Engine Coolant Temperature (ECT) sensor electrical circuit poor connection
- Faulty Engine Coolant Temperature (ECT) sensor
- Faulty engine coolant thermostat

P0118 VOLKSWAGEN Description: The Engine Coolant Temperature (ECT) sensor is used to detect the engine coolant temperature. The sensor modifies a voltage signal from the Engine Control Module (ECM). The modified signal returns to the (ECM) as the engine coolant temperature input. The sensor uses a thermistor which is sensitive to the change in temperature. The electrical resistance of the thermistor decreases as temperature increases.
When is the code detected?:When an excessively high voltage from the sensor is sent to ECM.

I hope this helps! Let me know if you need further assistance.

Hi can help me to fix code po125 on 2003 toyota corolla yuo know i try to fix but still came back the same code po125 , i change engine temperature coolant sensor and 02 oxyge sensor also 02 heater sensor...

Did you reset the Computer after you did the repair? After you replace a sensor that has stored a fault code you need to reset the computer in the car to clear the stored codes. Auto Zone or O'Rielley's may do it for you or try removing the Negative battery terminal for 60 secs.

P0125 obd code

P0125 Insufficient Coolant Temperature for Closed Loop Fuel Control
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.

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

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 coolant sensor, or a low coolant level).

Engine coolant temperature is lower than thermostat

This happens when the Engine Coolant Temperature (ECT) does not reach 75°C (167°F) despite sufficient engine warm-up time.

This happens usually when the thermostat/temperature sensor is faulty, and is bad for emissions and fuel consumption.

The repair cost may vary, even if themperature sensor is not an expensive part, after replacing the sensor there is need to reset the ECU (car computer module).

this is the temp sending unit. it sends a signal to the gauge on the instrument panel.
this is what you need to get to fix your temp gauge.
