Traction light/reduced engine power and check engine light coming on
A couple years ago my traction light was coming on. I took it to a mechanic who changed my gas pedal/sensor. This worked for some time. Then my traction light would come on and reduced engine power and check engine light would come on. I could pull over shut off my vehicle and turn it back on and the traction light was off and it would run fine. The check engine light would go off shortly after. I then changed the throttle positioning senor due to irratic idiling along with it. Well it seemed to work… on my way home I hit a bump on the interstate and the traction light came on reduced engine
Experienced mechanics share their insights in answering this question :
Hello. From what you describe, it would appear that your vehicle may be experiencing some sort of intermittent wiring or sensor issue. If the problem occurred again after driving over a bump, then it may be possible that a damaged or loose wire is shorting or having contact issues. A common issue that can cause stalling is a faulty crank position sensor or wiring. I would carefully examine the engine for any loose or damaged wires. If the Check Engine Light comes back on, I would recommend having the trouble codes scanned before resetting the computer.
How to Identify and Fix Common car Problems ?

When this warning indicator light comes on in the dashboard, this could be an indication of several issues such as faulty wheel speed sensors, a faulty steering angle sensor, a faulty rotational speed sensor or a problem with the steering rack.
This issue is related to the throttle position sensor, and can be caused by faulty wiring to the TPS, bad connection at the TPS, or a failed TPS. To correct this issue, the wiring harness, connector, and throttle position sensor must be inspected, tested, and/or replaced.
In most cases, the Engine Power Reduced warning indicates that your car`s performance has been intentionally limited. Your car`s primary computer, often known as the powertrain control module (PCM), triggers Reduced Power Mode when it detects a system failure.
Hello – the reduced power mode your truck drops into is electrical in nature, and most often a problem with bad ground wire connections between the engine and chassis, and the chassis and battery.
Faulty throttle and pedal position sensor
Any problem within the TAC system can cause the reduced engine power warning light to go on. One of the more common reasons includes one or both APP sensors in the accelerator pedal or the pair of TP sensors.
Low engine oil, loose cables, and a clogged catalytic converter commonly cause reduced engine power. Tighten loose cables or clean your oxygen and mass air flow sensors to bypass reduced engine power. Replace your battery or catalytic converter if they are damaged to override reduced engine power.
What the P2135 code means. This particular trouble code indicates that the Power Control Module (PCM) has detected an erroneous reading regarding the voltages transmitted by throttle position sensor A or B, the accelerator pedal position sensor and or the actual throttle plate.
A dirty air filter reduces the amount of clean air that is getting through to the engine, decreasing its power and performance. Replacing your dirty engine air filter with a new, clean one can improve the acceleration of your engine.
It depends on the cause of the reduced power. Often, the problems are minor. In rare cases, though, reduced power can cause more serious problems like a seized engine, or even an electrical fire.
Expect to pay between $100 and $500, including parts and labor, to get your engine back in shape. However, a catalytic converter issue can cost over $2,000.
What Does the P2135 Code Mean? The P2135 Chevy Silverado error code is defined as “Throttle Position (TP) Sensor 1-2 Correlation”. That`s exactly what the scanner tool will display alongside the P2135 code. If you`ve cleared the error codes in the recent past, and it came back, you`re dealing with a consistent issue.
Engine Power Loss
Your high-performance engine will lag if the O2 sensor is bad and tricking the engine control unit (ECU) into putting too much air in the combustion chamber. This creates a lean fuel mixture in the chamber and causes sputtering and power loss in the engine.
The oxygen sensor problem is the number one reason cars are slow to accelerate. The oxygen sensor is responsible for monitoring the air-to-fuel ratio in the engine, and over time it can become dirty or damaged, which will decrease power. Oxygen sensor malfunction will result in a mixture being too lean.
This issue is related to the throttle position sensor, and can be caused by faulty wiring to the TPS, bad connection at the TPS, or a failed TPS. To correct this issue, the wiring harness, connector, and throttle position sensor must be inspected, tested, and/or replaced. The most common cause is a faulty TPS.
Of course…. Failure to change motor oil on time can lead to many problems. For instance, if you don`t change motor oil in your car on time; Its power output will reduce.
P2135 can cause stalling out, so you should avoid driving with it.
Your engine idles more roughly than usual.
Extremely rough idling could indicate a problem in your spark plugs, cylinders, or fuel filters. No matter the source of your rough idle, any unusual engine sensations are good indicators that your engine is starting to lose power.
Often, the computer will apply the brakes just a little bit to slow that out-of-control tire down until the tread can get some bite on the road and prevent it from slipping. If further steps are required, traction control can even reduce engine power and torque until the tire slows down enough to get a grip.
Traction Control System (TCS)
The system brakes the spinning wheel(s) and/or reduces engine power to limit wheel spin. You may feel or hear the system working in the moment.

2012 equinox reduced power light engine light and traction light came on. Lost a lot of power got home and all light except engine
ANSWER : Your car has what is called a "safe mode" that will be engaged by the computer when it detects that something critical has gone wrong related to any of the major components in your engine chassis or power train. This may be related to a number of things, most of which should have been registered in the computer when the check engine light came on. I recommend having an expert from YourMechanic come to your location to inspect your check engine light and diagnose any codes registered by your vehicle’s computer.

Reduce engine power / check engine light is on
ANSWER : Hi there. Most of the time, reduced engine power is caused by a restriction of fuel, or the throttle body’s inability to efficiently mix air and fuel. This could be caused by a failing mass air flow sensor, EGR valve or other fuel system components. Since the check engine light is on, you should have a professional mechanic complete an inspection at your location to determine what codes are stored and which components require repair. This should resolve your issue.

Check Engine Light comes on after starting pickup
ANSWER : Hello there, thank you for asking about your 1992 Isuzu Pickup. A professional will have the correct equipment to read OBD1 codes. Retrieving the diagnostic trouble code(s) is the first place to start when diagnosing your vehicle. Increasing RPMs changes engine load, which can in turn affect many different sensors and components, causing the Check Engine Light to illuminate. The only way to narrow down the options and find the culprit is through in person diagnosis with an OEM compatible scan tool. A certified technician from YourMechanic can retrieve the OBD codes at your home or office.

Car sometimes give me acceleration and power issues. Engine power reduced message and engine light appear intermittently.
ANSWER : It is possible that your vehicle’s PCM has failed. This is somewhat of a common problem amongst many GM vehicles. If the computer has failed, this could be one of the reasons that no trouble codes are appearing and the fact that the problem is intermittent. It is possible that the computer is somehow getting overheated and by stopping the vehicle for a short period of time, the PCM cools down allowing the vehicle to run again. I would recommend having your PCM tested for proper function by a certified technician with experience in computer diagnostics.

Engine malfunction light, reduced engine power, engine powered down
ANSWER : Hi there. There are a lot of things that can cause this on your 2012 BMW M5. I usually start by scanning the computer for codes to see what comes up. If there are not codes then I load test the alternator and the battery to see if they are failing. Low voltage in the electrical system will cause this. If that is fine, then it is usually caused by a failing throttle body. I have seen a lot of these fail due to the motors in them hanging up. If the problem is only happening intermittently, this can make the issue hard to duplicate, but you can still have tests done on the car. If you are going to have this fixed, consider YourMechanic, as a certified mechanic can come to your home or office to test the vehicle and diagnose the Engine Malfunction Light.
