Chevy Monte Carlo Codes P0128, P0440 And P1440

I WOULD LIKE TO KNOW WHAT EXACTLY DOES CODES P0128, P0440, P0140 MEANS. Problem with my 2001 Chevy Monte Carlo. 3800 V6. GM Computer codes = P0128 P0440 P1440.

P0128- Coolant temperature beyond thermostat regulating temperature.
  Problable cause is just a stuck thermostat.
P0440- Evaporative emission system problem.
 A leak in the EVAP system has been detected.
P1440- EGR position performance.
 Most likely the EGR passages are plugged or the valve itself is stuck.

Chevy Monte Carlo

Problem with my 2006 chevy Monte Carlo 3.9L.
dash lights = service tire monitor system. GM Computer codes = I have a OBDII.
The service tire monitor system. Have remote start remote doors all work. Receiver not picking up a tire pressure reading. Shows all blank. Will OBD2 scanner help? Diagnosis exact problem please. The pressure comes and goes.

Your scanner would need to be able to read the Remote Control Door Lock Receiver (RCDLR). If one of the wheel sensors were bad, it should just show 1 tire pressure as a "--". You could try a re-learn procedure with or without a scanner. If there is an overall system problem, it says "service system" There is a bulletin for changing the receiver module, antenna, and remotes that may apply. There is an article on our site with more detail. Just go to our site and search "Monte carlo keyless" or Impala keyless".

The first step in any diagnosis of the check engine light is to get the computer (PCM or ECM) scanned for codes. Any time this warning comes on, a code is stored in the computer memory along with many data parameters that were present at the time of the fault.

2000 Chevy Monte Carlo Replaced pressure regulator and crank sensor. Engine starts and runs for about 5 minutes then the car dies and won't start until it cools down.

Were the parts replaced to repair this same condition? Any codes? What engine size? Well, the 3.4l engine has two crank sensors, a 24x and a 7x. The 7x is between the rear of the engine and the transmission. The 24x is behind the crank pulley. The crank sensor on the 3800 is behind the crank pulley. With either sensor behind pulley, a 'crankshaft position sensor variation' relearn must be performed.

I would definitely keep an eye on fuel pressure when it dies and wont restart. Have had some wiring harnesses rub through on a/c accumulator (bulletin). Usually that causes intermittent problems. Have had a few pcm failures that cause this also.

1997 Monte Carlo check engine light. My car was running fine until one day i was driving on the freeway and it just lost power meaning acceleration is that an oxygen sensor or an mass flow sensor.

The problem you are having could be many different things. An oxygen sensor going bad is not one of them. You first need to get the code scanned. That will tell you what system has a problem.

You could have a plugged catalytic converter, a bad MAF sensor, MAP sensor, or other. The stored trouble codes will tell you. But you can also have a fuel pump going bad or just a plugged fuel filter causing low pressure.

Question: what is code P0440 for a 1999 Astro van mean?
 Answer: P0440 is a general fault in the Evaporative Emission System. You may have a leak, a sensor or valve problem. Or maybe the gas cap is loose or the Astro van was running when filling with gas.

Question: I have a 2001 Chevy Monte Carlo SS. My dash lights went out and I had a ground repaired, not replaced. Then I had a new BCM installed. Did not fix the problem. When he repaired the wire it fixed it for about 3 or 4 mos. In sure it must be the same wire, I just need to know where it is.
 Answer: You will have to be more specific. Every module has many different grounds. Try calling the shop that did the work and ask them.

Question: What is code P0440 for a 2003 Chevy Monte Carlo?
 Answer: Code P0440 is a problem in the evaporative emission system. Most likely a leak. Most common on this car is what is called an EVAP that solenoid. But that will usually set a different code. Testing of the system different components would be needed to find out which part is bad.

I had same problem with dash lights. I replaced the headlight/dimmer switch. Perfect fix.

Question: i have a 2007 Chevy Colorado and i get a service code relating to the tires it says servc temp and the tire light flashes it goes out after a while i have checked the air pressure and it is fine?
