Diesel. Reduce power lite turned on. Shut off engine and started back up - lite is off. Can it be driven?


Jerry, Drive to a good shop. So many things can cause reduced power light unfortunately. The first step would be to get the truck hooked up to a scanner/computer and have the computer scanned for trouble codes. One thing that you could try is to drain the water from the water separator that is mounted on the frame under drivers front door. If the PCM picks up on water, power is reduced until water is removed/drained. It could be an exhaust sensor that is reading faulty. Unfortunately from here its impossible to tell you exactly what the fault is because there are just so many engine sensor inputs that could cause your problem. Check the attached links, forums,instruction and guides, Good luck

I have a 2003 Cadillac CTS. It continues to go into reduced power mode. How do I correct that.


Are you getting a ENGINE POWER REDUCED message ? Is the check engine light on ?
Reduced Engine Power Mode
Throttle Actuator Control (TAC) System
electronic throttle control .
When the ECM detects a condition with the TAC system the ECM may enter a reduced engine power mode. Reduced engine power may cause one or more of the following conditions:
?€¢
Limited torque


?€¢
Limited range of throttle movement


?€¢
Engine OFF


Your going to need to take this to a ASE certified repair shop or the dealer , you probably don't have the diagnostic tools to trouble shoot this problem.

engine power reduced means that the CPU has placed the ECM in a safe operating mode and reduced power to lessen the risk of serious engine / transmission damage. Stop and check oil level and coolant level at the radiator cap. have the fault codes read urgently so as to prevent damage to the units

I have a 2003 Saturn L300 6 cylinder. Last week the reduced power light came on and stays on every time the car is driven. The car performs the same but the heater is not working normally. Takes longer to...


This has nothing to do with the heat on the vehicle .
Reduced Power
The reduced power telltale is turned ON by the cluster when it receives a command from the body control module (BCM). The engine control module (ECM) (L81) engine sends a message to the BCM over the CAN serial data link.
The reduced power telltale is illuminated when the ECM is limiting engine torque in a low traction situation. This telltale is used only for the V6 (L81) engine application.
The reduced power telltale is turned ON by the cluster for 2-3 seconds, when the ignition is turned to RUN, for a visual system check.

Taking the vehicle to a qualified repair shop an having it diagnosed would be your best . Unless you have a factory tech 2 scan tool to read BCM DTC'S - diagnostic trouble code's an have factory diagnostic repair info.
Reduced Engine Power Mode
When the ECM detects a condition with the TAC system, the ECM may enter a reduced engine power mode. Reduced engine power may cause one or more of the following conditions:
• Acceleration limiting--The ECM will continue to use the accelerator pedal for throttle control; however, the vehicle acceleration is limited.
• Limited throttle mode--The ECM will continue to use the accelerator pedal for throttle control; however, the maximum throttle opening is limited.
• Throttle default mode--The ECM will turn off the throttle actuator motor and the throttle will return to the spring loaded default position.
• Forced idle mode--The ECM will perform the following actions:
• Limit engine speed to idle by positioning the throttle position, or by controlling the fuel and spark if the throttle is turned off.
• Ignore the accelerator pedal input.
• Engine shutdown mode--The ECM will disable fuel and de-energize the throttle actuator.
