Hello Rickey

How are you doing? Hope you are well. This can be a mechanical or electrical failure. As a first course of action, I strongly suggest that you remove the negative battery connector of the car and let it sit for 10 minutes or more before reconnecting it. This will reset the system and can get it back to it's normal operation. 

If the reset did not work here's what I want you to do. The throttle body can accumulate dirt over time and will require some cleaning. Below is what it looks like.

Dirty throttle body. As you can see, the butterfly is black and full of sludge.

Clean throttle body. Looks clean and free of dirt.

Please remove the air intake to gain access to the butterfly of the throttle body. Use a throttle body cleaner or carb cleaner to clean it. Wipe the dirt. Please use a screw driver to push the butterfly and spray ample amount of carb cleaner inside. Once you start the car, it may choke because of the cleaning agent. Once they all got out of the exhaust, the engine will run smooth again. 

If cleaning the throttle body doesn't help, I suspect that the crankshaft sensor is about to fail.

The functional objective for the crankshaft position sensoris to determine the position and/or rotational speed (RPM) of the crank. Engine Control Units use the information transmitted by the sensor to control parameters such as ignition timing and fuel injection timing. If it's failing or bad, the engine may stall or may not start at all. I'll be standing by for your response.

Have you seen my response Rickey?

He can be right about driving around the vehicle before the reset take effect. But if it did not change a thing then there are parts that will require some attention like the throttle body cleaning and crankshaft sensor replacement. You may want to suggest the following to your mechanic. 

You mean he did replace some sensors Rickey?

Ok

Did he use OBD II reader to clear the fault codes?

I see. here's the thing. The reader can see fault codes and these codes pertains to what part requires replacement. We can clear the codes at first and hoping that it will not act up. But if the problem persist, it means that clearing the codes is not enough. It will need some part replacements, the reader is a reference what needs to be replaced.

Regarding the mileage where the reset takes effect. It may take 10 to a hundred miles for it to reset. 

Yes Rickey you are right. The sensors that comes up must be replaced. You'll be good after the parts replacement. THat's the use of the OBD II reader

Is there anything else that I can add or help you with Rickey?

If he's saying that, please ask for a second opinion. You may want to find a different mechanic near you who can diagnose the car better. It's easy to say an electrical failure specially if it's not your forte

Hello Rickey.... Good day! May I ask if there's any history of PCM replacement?

Is this code appearing on the old PCM Rickey?

That's what I'm suspecting now because of the communication loss to the transmission Rickey. Is there any transmission repair shop near you?
