Diagnose check engine light Hyundai Elantra with stored diagnostic trouble code p0442 small evaporative emission system leak.
On this vehicle I was unable to find any On this vehicle I was unable to find any visible leaks with a smoke machine but was able to find a possible cause and in this video I show you how to easily remedy that thanks for watching be sure to subscribe to the flat rate mechanic for more money-saving auto repair videos.
1. Monitor the fuel tank pressure sensor voltage either with the scanner or using at voltmeter (Green/Orange wire pin 33 at the Electronic Control Module). The fuel tank pressure sensor should have approximately 5 volts on the Red wire (pin 44) and a ground on the Blue/Black wire. With atmospheric pressure on the system, the voltage on the Green/Orange wire should be near 2.5 volts.
2. Next ground the canister close valve Blue/Black wire, this should close the valve and seal the system.
3. With the engine idling, locate the purge control valve (under the throttle body, inline of the vacuum hose) and tap the Yellow/Orange wire to ground while watching the fuel tank pressure sensor voltage. Bring the voltage down to near 1 volt and stop tapping the ground. The voltage should hold if there are no leaks. If the voltage starts to rise pinch off the hose between the canister and the fuel tank. If the voltage stops rising the leak is in the canister, canister close valve or hoses.
In this video, I will show you how to diagnose a bad lifter or a hydraulic lifter noise or tick on Chevy and GMC trucks with a 5.3l, 6.0l, or 6.2l.
First I will identify what cylinder is affected by using the factory GM scan tool. Once we know that we will be pulling the valve cover of to check the lifter on this Chevy truck.
In this video, I will show you how to fix a u1000 code in your car. In many instances, if you have communication errors in your car there’s a good chance that it will not start and the scan tool will not communicate with the modules, therefore, making it very hard to diagnose.
In this video, I will show you ways around that and how to find out which model is are not communicating. I will be using the factory GM scan tool in this video. #U1000 #FlatRateMechanic #HowTo
The class 2 communication Data Network is very sensitive and anytime you have a module failure on that circuit you have to run the possibility of Bringing Down the whole network. Which in turn can cause many problems for you as a car owner and an auto repair technician. Communication error codes can be very tricky to diagnose sometimes.

In this video, I find a common ground wire that was broken or had a bad connection and was able to repair it and it took care of all the diagnostic trouble codes on this dodge Patriot.
2007 Caliber 2.0
2008 Caliber 2.0
2007 Caliber 2.4
2007 Patriot 2.4
Customer Concern: Trouble codes P0647, P2010 and P0032 are setting. The Air Conditioning (A/C) does not work.
Average Reported Mileage: 120075
Tests/Procedures: 1. These circuits share a common ground. If the ground is missing/poor, circuit high trouble codes will set.
2. Inspect the Z916 ground circuit (Black or Black/White wire) to the G110 ground. G110 ground is located on the right frame rail just ahead or below the washer reservoir. If the ground is poor/missing, add a redundant ground using a jumper wire and test for further problems.
How to diagnose a cylinder misfire in your car. Check engine light P0300
In this video will be diagnosing a cylinder misfire on a Cadillac DeVille 4.6 L Northstar motor. I will show you how to identify which cylinder is misfiring if you have a random cylinder misfire P0300 and once you find out what cylinder is misfiring I will also show you how to find out what’s causing the misfire.
Will be swapping spark plugs will be swapping ignition coils and watching the misfire graph on the scan tool to see if the misfire Falls the ignition coil or spark plugs. Also, show you how to pull fuel injectors with the GM Factory scan tool.

Flat Rate Mechanic here and in this video I have a 2010 Honda Civic that the customer was complaining of the AC cutting out when it gets hot. So whatever is able to do is monitor the power actually going to the AC compressor clutch. And when the problem actually occurred there was still power being applied to the AC compressor.
I was actually able to tap on the front of the AC compressor clutch and it would engage indicating that the AC compressor clutch coil is getting weak. And typically they will fail when they get hot because resistance in the electric circuit goes up and the magnetic coil in AC clutch is made up of just a huge winding of copper wire so resistance relative to heat when they start to fail can go up quite a bit.

In this video, I will go over diagnostic trouble codes that are very common to the GM and Chevy 3.6 l V6 engine. They’re all timing related codes and the most common cause for it is a timing chain to stretch over time or for the timing chain tensioners to go bad.
In some instances, these codes can also be caused by low or dirty oil or a plugged or failed valve timing solenoid when should be always be checked first.
GM has extended the warranty on their timing chains to 120000 Miles and 10 years.
Customer Concern: Engine Control Module (ECM) DTC P0008, P0009, P0016, P0017, P0018, P0019 The engine has a surging, fluctuating idle. All 6 DTCs reset at the same time.
Average Reported Mileage: 89737
Tests/Procedures: 1. Remove the Crankshaft Position (CKP) Sensor.
2. Using a boroscope, inspect the crankshaft reluctor.
3. Refer to pictures in PIP3423C for illustrations for the position of the reluctor vs the counterweights.
4. If a boroscope is not available, removal of the oil pan will be required.
5. If the crankshaft is OK, check the timing chains.
6. Refer to GM 11340C, Special Policy that will warranty the timing chain for 10 years or 120,000 miles.
Tech Tips: Refer to GM PIP3423C; for 2007 Buick and Cadillac refer to 07-06-01-013B; for 2007 GMC, Pontiac and Saturn refer to 07-06-01-014.
In this video, I go into detail on why a p0445 large evap system leak sets and hoe the gas vapor system works and why it will set a p0455.
There are a number of different reasons that could cause a p0455 and the #1 reason being the evap vent valve and they are pretty easy to test. In this video, I will be testing the vent valve and the
evap purge valve with a power probe http://amzn.to/2FN2r70
I will active them with the power probe then blow into them to make sure they are sealing properly. And if they don’t that will be the cause of your large EVAP leak. The vent valve is very common and I hope this video helps a few people save a little money on their auto repair bills. Thanks for watching the Fate Rate Mechanic.
In this video, I will give you a very fast overview on how to remove and replace your rear axles so you can the leaking axle seals can be replaced. There are also a few tools you will need, you can get cheap on Amazon here are the links:
