SOURCE: 03 Mazda 6: Check engine light on, code po174

The oil pressure sensor does not have much to do with the P0174 code so the leak on the gasket is not the cause, usually it is the air mass sensor, or the intake sensor. if you have a leak of oil, this might as well mean that whoever changed the oil did not put the right specs of it and this caused the oil to get through. After some time you will experience that the rpms will reach only certain level and won't go higher. Change oil to the right specs and get the sensor cleaned if not to late or replaced (will be expensive). Gasket change wil be needed as well.

SOURCE: location of the ect sensor

It's just to the drivers side of the valve cover. Attached to the coolant flange under the hose for the PCV. In this pic if it works.

Where is the Coolant ECT Senor and my Thermostat on a 2005 Mazda Tribute . I know it's a 2.3 Liter V-6


If its a 2.3 it should be a 4 cyl. The V6 engine is a 3.0 cu in.
The thermostat should be under the housing where the upper radiator hose connects, and the sensor should be nearby.
If the thermostat is not in the upper housing check the lower radiator hose connection.

PO128 code in my car how can i get it off


This means that the engine's PCM detected that the engine has not reached the required temperature level within a specified amount of time after starting the engine. The intent of the P0128 code is to indicate a faulty thermostat. Similar codes: P0125
In determining the engine did not reach a "normal" temperature, it takes into account the length of time the vehicle has been running, the intake air temperature (IAT) sensor reading, the engine coolant temperature (ECT) sensor reading, and the speed of the vehicle.
Symptoms You will likely not notice any drivability problems other than the MIL illumination.
Causes A code P0128 may mean that one or more of the following has happened:
  • Low engine coolant level
  • Leaking or stuck open thermostat
  • Faulty cooling fan (running too much)
  • Faulty coolant temperature (ECT) sensor
  • Faulty intake air temperature (IAT) sensor
Possible Solutions Past experience indicates that the most likely solution is to replace the thermostat. However here are some suggestions on troubleshooting and repairing a P0128 OBD-II code:
  • Verify coolant strength & level
  • Verify proper cooling fan operation (check if it's running more than it should). Replace if necessary.
  • Verify proper engine coolant temperature (ECT) sensor operation, replace if necessary.
  • Verify proper intake air temperature (IAT) sensor operation, replace if necessary.
  • If the above items check out good, replace the thermostat
  • If Nissan vehicle, check for Technical Service Bulletins (TSBs), as the ECM may need to be reprogrammed to correct the P0128 code

P0118


As with all engine codes there is no one solution fits all, here is the info on the code from the diagnostic material.
P0118 - Engine Coolant Temperature Circuit High Input
Possible causes - 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 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.

My 2005 cobalts cooling fan only comes on when the a/c is one. i have a new fan, thermometer and my water pump is not leaking out water so i doubt its the water pump.


SOUND LIKE ENGINE COOLANT TEMPERATURE SENSOR OPEN OR BAD.HAVE THE ECT SENSOR CHECK WITH CODE SCANNER SEE IF ENGINE COOLANT TEMPERATURE SENSOR READING TEMPERATURE RIGHT.IF ENGINE COOLANT 200 DEGREES AND SCANNER SHOWS 80 TO 100 DEGREES YOUR ECT SENSOR BAD.

The fans are turned on by the PCM, if the PCM is not telling the fans to turn on, they won't even if everything tests fine.
