Instead, spray the cleaner on a soft cloth and wipe the parts. Equipped with either a V-6 or V-8, the Trailblazer has computer engine management systems to optimize and regulate performance. I bought a 2004, 4. Other P1100 codes can involve the throttle system, coolant, intake air temperature and fuel system errors. Basically I'm looking for a good place to start. In the process the converter heats up to normal temps.
The code means the cold start-warm up cycle did not produce the expected emission reading. Don't forget to wear safety glasses! Basically I'm looking for a good place to start. Chevrolet Trailblazer P1400 if your catalytic convertor fails completely, you eventually won't be able to keep the car running. P1500 codes can be problems with the theft deterrent system, backup power supplies, transmission and gear change difficulties and climate control. How to Fix Repairs for this code are as easy as the diagnosis above.
Check the air filter element for dirt or signs of deterioration. This issue is intermittent and I haven't been able to get it to do it again. If there are no other codes, inspect for vacuum leaks, restrictions, and damage. This P0506 code is one that's sometimes triggered on vehicles that have electronic throttle control. They rely on sensors and electronics to control the throttle. I removed a coil pack and looked at the plug, again it was really clean looking. Monitor the Cold Startup parameter.
Like others have said- it was easy and the engine runs smoother audibly and by feel. I swapped Throttle-Body with my Trailblazer. This P0506 code is one that's sometimes triggered on vehicles that have electronic throttle control. You should also check that the spark plug gap is set properly. That is, they don't have a regular throttle cable from the accelerator pedal to the engine. So when you changed it, this caused all your problems. As for the P1400, I'd look at the O2 sensor on the manifold.
Next, check the engine mechanical for items that could change the airflow into the combustion chamber. My 2007 Envoy turned on its check Engine light last night. Could be a list of things such as the air filter, thermostat, intake leaks, and so on. This diagnostic runs once per trip when a cold start has been determined. Possible Causes Many factors lead to this error code. It used to have a 'raspy' sound and feel recently but now accelerates very smoothly. She is sitting around 75,000 miles.
I don't want to just through parts at it. Note: This video is being performed by an experienced tech. No guarantee or warranty is implied. Regardless of how you approach it, you should get this fixed right away. I do mine every 50k as a minimum maximum? Cleaning your throttle body should take care of both problems. During a cold start, the engine idle speed is elevated and spark timing is retarded to allow the catalyst to warm quickly. So when you changed it, this caused all your problems.
If the plug wires are out of sequence, the explosion occurs at the wrong time. Aug 15, 2012 Cleaning your throttle body should take care of both problems. When finished, hook the battery back up and around for 20 minutes or so with all accessories off, so the computer will relearn a properly functioning throttle body. Now don't ask yourself; What should you do with P1400 code? There are potentially other symptoms as well. In late model vehicles with an electronic throttle body, you should remove the throttle body and perform a complete cleaning of the throttle body bore and throttle plate. No change in condition,,, which means the throttle body is not bad.
Haven't changed the plugs or coil packs since she was born. Posted on May 23, 2011 You may want to do some more research on this one. When finished, hook the battery back up and around for 20 minutes or so with all accessories off, so the computer will relearn a properly functioning throttle body. The improper timing of the explosion sometimes pushes the cylinder the wrong direction or interferes with the turning of the crank. Probably not connected with the P1400 though. The engine is at idle with no input from the accelerator pedal. That method dumps extra oxygen into the converter to react with the extra fuel and burn it off.
So I'll be cleaning my throttle body this weekend too. This P0506 code is one that's sometimes triggered on vehicles that have electronic throttle control. There are potentially other symptoms as well. Catalytic converters must be warm before they can work properly. They rely on sensors and electronics to control the throttle.
