TIQ 000190.01 (TIQ 190.01) – Engine Speed Out of Range Low
TIQ 000190.01 (TIQ 190.01)
Code: 000190.01
Shortcode: 190.01
Description:
This diagnostic trouble code is generated when the control software detects that the engine speed has dropped too low. This can occur due to insufficient fuel supply, air intake issues, or mechanical problems. To prevent the engine from stalling, the transmission is shifted into neutral.
Reaction:
Upon detection of low engine speed, the control software automatically shifts the transmission into neutral.
Recommendations:
- Inspect Fuel System:
- Check for adequate fuel supply and pressure.
- Ensure fuel filters are clean and not clogged.
- Air Intake Check:
- Verify that the air intake system is free of obstructions.
- Ensure air filters are clean and not restricted.
- Engine Maintenance:
- Perform regular maintenance checks on the engine to ensure it is running smoothly.
- Look for any signs of mechanical issues such as timing problems or compression loss.
- Electronic Control Unit (ECU) Diagnostics:
- Use diagnostic tools to check for any ECU errors or malfunctions.
- Update ECU software if necessary.
Note:
Maintaining the engine at optimal operating conditions is crucial. Regular inspections and maintenance of the fuel and air systems can help prevent engine speed issues.
