You’re welcome!

Good to know, thanks for the tip!

You're welcome!

Hi, it's really hard to diagnose without a PO code, there are so many things that can affect the acceleration of a vehicle. It doesn't hurt to clean your map sensor or replace it, but it's kind of a shot in the dark without a PO code.

You’re welcome!

yes

That’s the goal. Glad it helped!

If you notice issues like rough idling, poor fuel economy, or a check engine light, cleaning the MAF sensor can be a good first step. Cleaning is often effective if the sensor is dirty but not damaged.

Thank you. An illuminated Malfunction Indicator Light (MIL) is typically the initial indication of a faulty ECM. However, as the MIL may also indicate other issues, such as a malfunctioning sensor or a wiring problem or a battery with a dead short. It's important to use a Scan Tool to verify that MIL illumination is a result of a faulty ECM before proceeding with repairs.Yes, the ECU worked as advertised.

Sounds like a possible vacuum leak, check all your hoses.

@TheAutoTeacher ok, ill inspect. The sound isn't like an air sound, or hiss. Its more like glass on the ground and someone steps on it and drags their foot backwards, like a scraping but audibly it's like a "shhhhh" but not consistent, it goes away, comes back. If not a leak, what else?

Miles?

@@TheAutoTeacher 151k. I bought a new pcv valve. Damn that was hard to take off. Do i put dielectric grease on the end of it to turn it in easier?

Yes

Bank 1 will have an upstream oxygen sensor and a downstream oxygen sensor if that's what you're asking.

The procedures should be very similar.

No

Not sure, auto repairs can be done in a variety of ways depending on the complexity of the issue, the tools available, and the mechanic's experience.

@@TheAutoTeacher I'm gonna try it. If you are wrong I'm going to be super mad. lol.

First make sure the battery is correct for your vehicle!! Batteries often have a specific size for the vent tube opening. If the new battery's vent hole is different in diameter or design than the old vent tube, call the auto parts store to check if the new battery is correct or comes with a specific vent tube or adapter to fit your application.Most auto parts stores will carry battery vent adapters.

Hello, unfortunately their are many reasons for a PO420 code, it most likely indicates a faulty catalytic converter. I would start with the oxygen sensors upstream and downstream one at a time. Depending on vehicle mileage, a poorly running motor caused by spark plugs/exhaust leaks and fuel injector problems can also throw a P420 code. As long as the P0420 is the only code and the engine runs normally then driving the vehicle is not a problem.

Removing the coolant temperature sensor on the lower radiator hose you will lose a majority of the coolant. I would jack the car up and use a clean bucket and remove the lower cooling hose hopefully catching most the coolant. Once drained ,you can then replace your coolant temp sensor and reinstall the hose. YES, to bleed the cooling system, leave the car on the jacks so the the coolant tank is the highest point in the system ,take the coolant tank cap off and start the car .While the engine warms, it will "burp" all the air trapped in the system through the coolant tank, watching closely the cars temp as it rises, to make sure the engine doesn't overheat. At some point the coolant will be so hot that it will start to boil out of the coolant tank, then put the coolant tank cap back on.Once the engine cools down repeat if needed, until no air bubbles are seen in the coolant tank and the engine temp is stable.

You can purchase a less expensive part, just make sure that it's fits the specifications of the manufacture and that it's coming from a reputable supplier.

Thank you, no need to disconnect the battery. If it fixes the problem the light will go off after a short drive, or you will need to clear it with a OBD2 scanner. If the light stays on the the MAF will need to be replaced.

VVT Solenoid

Listed in Parts description through Amazon, or at any automotive retail store.

You’re welcome and good luck👍

Just replaced the one that is malfunctioning.

@@TheAutoTeacher thank you

At the time of the video it was correct, not sure what might've changed on Amazon. Make sure you include all your vehicle information and the part number to make sure that you get the correct part for your specific vehicle.

Wanted to follow up. Part you list worked fine. Not sure why it listed as not. Thank you for your walk through, as well as your reply and help. Already subed and liked

You’re welcome!

👍

Congrats and you’re welcome!

Thank you, a 4-Way Battery Terminal Cleaning Tool and a socket set with various extensions.

Advance auto parts, some manufacturers are now offering a aluminum version of this.

You’re welcome!

Lithium grease is a top choice in automotive applications due to its exceptional resistance to water, oxidation, and corrosion.

You're welcome.

No, carburetor cleaner is too strong and can damage the delicate plastic parts inside a MAF sensor ,it also leaves a residue that impacts the sensor's operation.

It's a short 1/4 ratchet with a 5.5 socket .

It's just for supplying fresh air to your air filter box.

Yes, it would be the same basic principal, the only difference would be if it has electronic dampening then you would just have to plug/unplug .

Time to replace it!

You’re welcome!

You have two oxygen sensors on your 2.4 Toyota motor. You will want to replace the one after the catalytic converter for the PO138 code.

@TheAutoTeacher thank you. I just watched it live on my hour ride home. The sensor 1 is bouncing around 3.o volts which is crazy high I heard and the 2nd(downstream) wasn't reading any this morning but I tapped on it , uplugged and plugged back in. That was reading at steady speed around .4 to .5 and the waves on the graph seemed consistant. I think I'm just going to replace both. OH and my STFT stayed under +8 and -8.

P0345 stands for “Camshaft Position Sensor “A” Circuit (Bank 2). It could, but there are other underlined timing/ wiring issues that could also be causing the problem. It's a good place to start.

yes

@ thank I appreciate it. They are trying to charge me 200-600 to find and fix it.

👍

It might be worth considering as a potential culprit. A malfunctioning or clogged solenoid can affect the timing and cause the P0016 code.The P0016 code stands for “Camshaft Position A - Camshaft Position Correlation (Bank 1)”, which means your crankshaft and camshaft are not in sync. The most common causes of the P0016 code include a damaged timing chain or belt, a faulty camshaft or crankshaft reluctor wheel, and a bad camshaft or crankshaft sensor.
