What does the Check Engine light on a PCM do?
PCM (Powertrain Control Module) For instance, the check engine light will illuminate if the engine coolant temperature is too high, or too low. These lights alert drivers to issues, but they alert technicians that diagnostic trouble codes (DTC) are stored in the PCM for retrieval and diagnosis.
What are the warning lights on a PCM?
The PCM is programmed from the factory to use these warning lights to alert the driver of failure when certain conditions are met. For instance, the check engine light will illuminate if the engine coolant temperature is too high, or too low.
What are the symptoms of a PCM failure?
Symptoms of Wear or Failure of the PCM (Powertrain Control Module) 1 Check Engine Light illuminates with codes that cannot be repaired are stored. 2 Several unrelated trouble codes are set simultaneously. 3 Vehicle may not start or run. 4 Poor engine performance. 5 Engine stalls while driving.
What does the engine management warning light mean?
The engine management warning light is different from the other lights on your dashboard, as it doesn’t alert you to a specific fault. Unlike the coolant temperature warning or low oil level warning lights, the engine management light (EML) can be triggered for a number of reasons.
What causes the p0028 OBD-II trouble code?
What causes the P0028 code? The ECM activates the intake valve solenoid for bank 2, but the valve lift mechanism did not change. The intake valve lift solenoid for bank 2 is shorted or has an open circuit.
What does p0028 mean on an intake valve?
P0028 is a diagnostic trouble code (DTC) for “Intake Valve Control Solenoid Circuit Range/Performance (Bank 2)”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
What does the you mean on a check engine light?
The letter “U” indicates network codes which are used for problems like module failures and losses of communication. Note: Only professional-grade or dealership scan tools are able to diagnose codes outside of powertrain codes. Step 3: Determine if the codes are Society of Automotive Engineers (SAE) codes or manufacturer-specific.
What does it mean when service engine light comes on?
When the light comes on, a code is stored as the reason for triggering the light. When you take your car in to get it checked out, the mechanic hooks up a little diagnostic computer to your vehicle’s computer. They will then get a code and description that tells them what the issue is.
