Question about 2004 Chevrolet Tahoe

1 Answer

While driving down the highway, my 2004 Chevy Tahoe displayed a reduce engine power message. The accellerator pedal at that point had no effect on the engine even though it was still running. My manual told me to check the gas cap by lossening it then retightening it. It corrected the problem for about 30 miles, then the solid engine light came back on with the same message. After going through the gas cap procedure again several times, the light and message warning went out. I made it home but am concerned about driving the vehicle for any distance at all now. What may be the prob

I just had the transmission in my 2004 trailblazer


There is a harness in the engine compartment that has grounded out or shorted. The message 'reduced power' will flash across your driver information display on your gauge cluster. This is somewhat of a common problem for full size Gm trucks (silverado, tahoe, suburban, etc .) and trailblazer/envoy vehicles.

My 2003 chevy tahoe will not accelerate pass 30mph what could be the problem?


Your problem could be in the Transmission, but most likely it is caused by a sensor / electric part called an Accellerator-Pedal-Position-Sensor (APP-Sensor. If it is the APP Sensor, then you should be getting a signal in the information center saying "reduced power" or a Check-Engine Light.

Got a display message "Reduced Engine Power" the


When you receive this message it means that the computer has put the engine and components into protection mode. This computer has done this to prevent any further damage to the engine or transmission. You have to have the computer of the vehicle scanned to find the problem then you need to get it fixed right away. It could be a number of different causes overheating,Low Oil Pressure,Transmission pump problem, low coolant level, low oil level. Their is really no way of telling from this end without seeing the vehicle.Start by checking all fluid levels, Oil,Coolant,Transmission.If all this is good scan the computer with a OBII scanner or take it to a garage and get it scanned. It may just be something simple or it could be something very serious.Do not drive the vehicle it is worth the cost of a tow truck to prevent further damge if you can not determind the cause and fix it yourself.

The check engine light keeps coming on in my 2004 Chevy Tahoe. At first when it came on, it would show a warning message that states Reduced Engine Speed and the Tahoe wouldn't have any power. Now, it's...


Most auto parts stores have Scanners that can read the actual Codes causing the check engine light- usually for FREE. Google the Codes to determine what needs fixed.

Do not continue to drive it, as it may cause permanent damage!
