Suggestions for Resetting Diminished Engine Energy Mode
7. Examine the Throttle Place Sensor (TPS)
The throttle place sensor (TPS) displays the place of the throttle valve. A defective TPS can ship incorrect indicators to the engine management module (ECM), which may trigger the ECM to place the engine into lowered energy mode. To check the TPS, you should use a multimeter to measure the voltage output of the sensor. The voltage ought to change easily as you progress the throttle valve. If the voltage output is erratic or doesn’t change in any respect, the TPS could have to be changed.
Listed below are some further suggestions for resetting lowered engine energy mode:
- Disconnect the battery for 10 minutes. This can reset the ECM and will clear the lowered energy mode.
- Examine the air filter. A grimy air filter can limit airflow to the engine, which may trigger the ECM to place the engine into lowered energy mode.
- Examine the spark plugs and wires. Defective spark plugs or wires may cause misfires, which may additionally set off lowered energy mode.
You probably have tried the entire above steps and your car continues to be in lowered energy mode, you might must take it to a professional mechanic for additional analysis.
Sustaining a Wholesome ECM/PCM Unit
The Engine Management Module (ECM) or Powertrain Management Module (PCM) is the mind of your Chevy’s engine. It controls every part from gas injection and ignition timing to emissions and efficiency. A defective ECM/PCM may cause a wide range of issues, together with lowered engine energy. Listed below are some suggestions for sustaining a wholesome ECM/PCM unit:
