After a rain and my truck sitting I start it and check engine light comes on and bogs down. Throws a p0743 and a p0741 code along with others. Sometimes it clears itself and sometimes it doesn't. It also happens when I turn left or if I hit a bump going slow
My car has an automatic transmission. I changed the solenoids in transmission pan, fluid and filter. The truck has 250k miles on it. The overdrive button on gear shifter will not illuminate when pressed and my third brake light was not working so I changed the bulb in it
Hi there. Looking at the OBD-II trouble codes you provided us and your symptoms, it appears you have a torque converter solenoid or torque converter issue that is causing the sluggish driving and check engine light. The Powertrain Control Module (PCM) will set the P0741 diagnostic trouble code when it notices a difference between the rotational speed of the torque converter and the transmission input shaft that is greater than 200 revolutions per minute (RPM). You might want to read this article about the P0741 OBD-II trouble code as it will provide you with common symptoms, causes and repair solutions.

A steady glow typically means something less serious but a flashing check engine light indicates that your vehicle`s engine is in serious trouble and service is needed immediately. If your check engine light is flashing in your Ford F-250, we highly recommend not to drive the vehicle and schedule Ford service today.
One of the most common reasons for seeing the check engine light on a diesel truck is the aftertreatment system. Diesel trucks have nitrogen oxide (NOx) sensors that measure what your car is putting out into the environment.
Your “Check Engine Light” is simply a warning light that has received information from a sensor connected to your vehicle`s ECM, or “engine control module”. It can be an indicator of needed maintenance, or it could also be warning you of a major component failure.
If the check engine light in your 2021 Ford F-250 starts flashing, that means that the problem needs precipitous attention and your Ford should be brought in today. This blinking light commonly indicates a severe engine misfire allowing unburned fuel to be drained into the exhaust system.
Flashing DEF Lamp and Solid Check Engine Lamp Indicates that DEF level is critically low, incorrect DEF type or an SCR system issue for more than five hours. Driver will experience a severe loss of engine power.
A loose gas cap is one of the most common reasons for the check engine light to go on. Check that your gas cap is screwed on securely and that it`s in good condition. If you have a tank of bad gas in the car, your check engine light may come on.
Can you drive a car with the engine light on? It`s okay to drive for a few miles, but be sure to schedule an inspection of the engine as soon as possible. If the check engine light comes on while you`re driving, don`t panic! Pay attention and see if the car is driving any differently than normal.
Check your gas cap first. Many vehicles have a loose gas cap indicator that will be triggered before your check engine light comes on. If your gas cap is loose or the seal is not tight, the vapor leakage can cause your fuel system to trigger the check engine light.
If the check engine light illuminates, it will either blink or remain constantly illuminated, depending on the problem. A blinking light, or in some cars a red light instead of a yellow or orange light, indicates a problem that needs immediate attention. Either way, you should have the vehicle checked by a mechanic.
CHECK ENGINE LIGHT BEST PRACTICES
If the light is not flashing, check the gas cap. Oftentimes if the gas cap wasn`t tightened enough, the check engine light will display. If tightening the gas cap does not make the light go away, take the vehicle in to have the diagnostic codes looked up.
Engine Oil warning light
The yellow oil warning light comes on when either the oil temperature gets too high, or the oil level or pressure is too low. If the oil is not lubricating the engine effectively, it could lead to expensive or even irreparable engine damage, so it`s important to act quickly.
So how do you know when you have an emergency? You can judge how serious an issue is by looking at the warning light. The check engine light can show up in two ways: Solid yellow/amber light: Indicates a less urgent issue. Flashing light or red: Indicates a severe problem that needs immediate attention.
A check-engine light will shut itself off if the condition that caused it is remedied. So, if your converter is marginal, and you did a lot of stop-and-go driving, which creates high demand for the converter, that might have turned on the check-engine light.
What concerns can a loose gas cap cause, well a check engine light? A loose gas cap will not only let in dirt and grime, but it can also allow fuel vapors to escape. These vapors can trigger an error in the emissions system, which would light up the check engine light.
In most cases, a faulty camshaft position sensor will cause a vehicle`s check engine light to illuminate. This occurs when one or more timing-related diagnostic trouble codes are logged by a vehicle`s PCM.
In some cars, a yellow check engine light means there is a problem that needs to be investigated and a red or flashing light means there is a serious problem and you need to stop right away. Your gauges will help you to determine problems like overheating and low oil pressure.
How long can you drive with the check engine light on? Once you see the check engine light, it is safe to drive with the light on for 50 to 100 miles. This is because if the issue is with the sensors, then this will buy some time for it to reset, turning the check engine light off.
Clock some miles
To make sure the check engine light does not reappear, it`s recommended that you drive your car 30 to 100 miles. This enables the vehicle`s “Drive Cycle” to reset, as the various sensors need time to recalibrate.
A dirty air filter can cause your vehicle to throw a Check Engine code. During this instance, the Check Engine Light of your vehicle will turn on. The light turns on because your vehicle is sensing that its engine isn`t receiving enough air.
If your vehicle is revving inconsistently or your RPM gauge is up and down, this may be a sign your fuel injector needs a clean. A contaminated fuel injection system or worn fuel injector can often supply inconsistent amounts of fuel to the engine, resulting in poor performance. Misfiring.
A clogged air filter, broken injector or injector pump, faulty turbocharger, or broken EGR valve, can cause an imbalance of the air/fuel ratio, creating black exhaust. Oxidation of the Oil. When a diesel vehicle sits too long and isn`t driven regularly, the oil can start to oxidize.
A spark plug usually lasts about 30,000 miles, but cleaning them and maintaining them periodically lets your engine perform better and increases your plugs` lifespan. If you see rust, carbon, gunk, dust, or any type of buildup during the inspection, it may be time to clean them.
The most common causes of misfires are worn, improperly installed, and mishandled spark plugs, malfunctioning ignition coils, carbon tracking, faulty spark plug wires and vacuum leaks.
Low oil pressure is a common cause of a check engine light turning on, and it can seriously interfere with your car`s performance.
