You must have a thermostat installed that done not open to soon. Yours could be stuck open and it is letting the coolant circulate all the time. Your motor might perform better but you wont be able to pass the inspection. Some people remove the thermostat to prevent overheating and if you are not the original owner you might want to check that also.

Po128 is the code. What's the problem


Well, I can't give you any specific information regarding your vehicle because you forgot to mention what kind of vehicle you have. (This is kinda important if you really want some help figuring out what is wrong with your car)

The "Generic OBD" of code P0128 is "Coolant Temperature Below Thermostat Regulating Temperature"

The most likely cause is a stuck-open thermostat, however, I have also seen defective Engine Coolant Temperature (ECT) sensors also cause this code.

Engine light on code p1296 was found the car is a 2001 jetta 80000 miles runs good all censor replace in the last five months it warms up fast idle good. pass smog. what can the problem be. thank you...


VW DTC 17704 (P1296) - Cooling system malfunction.

Coolant Temperature Sensor (CTS) is faulty and reading an incorrect temp'.

Replace with the new version of the sensor, clear the code.

If indicated coolant temp' is too low the thermostat is sticking open.

I have a 2002 Chevy Cavalier. The engine light came on and it was the catilac convertor that needed to be replace. Mechanic completed the job and now the engine light is off. Took the car in for...


They are refering to the Drive Cycle not being completed. There are 7 monitors that have to complete in order for them to have a passing signal where the Smog Tech / Smog Machine can say its a pass in that part of the test.

This is what you need to do hope it helps out.

Cold Start
  • The barometric pressure (BARO) is more than 72 kPa .
  • The engine coolant temperature (ECT) is below (84°F ).
  • The intake air temperature (IAT) is below(84°F ).
  • The difference between the IAT and the ECT is(13°F ) or less.
  • The battery voltage is between 9.0-16.0 volts .
  • The fuel level is between 1/4 and 3/4.
The DRIVE CYCLE:

Inspection/Maintenance (I/M) Complete System Set Procedure - Steps 1-4 155390324
Inspection/Maintenance (I/M) Complete System Set Procedure - Steps 5-7 159960079 READ THIS ALL THE WAY THROUGH 1ST BEFORE YOU ATTEMPT IT, SO YOU KNOW HOW TO START AND WHERE YOU NEED TO DRIVE THE CAR TO HAVE ALL THE MONITORS RESET.

If you have more questions let me know. Good Luck.

1999 isuzu rodeo no heat the temp reads cold


The water temp (coolant temp) is cold all the time? Thermostat stuck open. Replace, not good for car. Computer can't adjust well to that and will cause fuel economy issues, never allow car to warm up properly. Opposite of thermostat stuck shut causing overheating. If the water can't be restricted enought to heat up and then be maintained at the correct temperature your car is not operating efficiently, won't pass smog I'd assume, etc. Thermostat is at end of upper radiator hose in thermostat housing. Two bolts to remove. Pop out thermostat and see if its stuck open. It'll have a gap if it is and it will be shut if not. You can boil water vigorously and hang your thermostat in it with a wire or something and watch it. It should move open from closed at a noticeable rate. When removed after fully opening, it will close as it cools. If it doesn't move and is stuck or moves EXTREMELY slowly it's done. Replace gasket, replace thermostat, light coat of sealant on gasket if you wish and torque down evenly. Replace lost coolant. Hope this helps.
