How do I fix error code P1400?
How do I fix error code P1400?
What repairs can fix the code?
- Repair damage or replace the air intake system.
- Remove any carbon that has collected in the throttle bore.
- The MAF (mass airflow) sensor elements should be cleaned.
What does Engine code P1400 mean?
DTC P1400: Cold Start Emission Reduction Control System. Circuit/System Description. The catalytic converter must be warmed to efficiently reduce the emissions. The cold start strategy is to reduce the amount of time it takes to warm the catalytic converter.
What is the type of error code for powertrain?
Error code P0203 occurs when the PCM (Powertrain Control Module) or ECM (Engine Control Module) detects a cylinder 3 injection circuit malfunction. In other words, this error code is triggered when these modules determine a low or high voltage drop or resistance at the injector 3.
What is cold start emission?
Once an engine heats up, components like Corning’s clean-air substrates dramatically improve air quality coming out of vehicle tailpipes. But cold-start emissions – the dangerous gases produced during the first 60 seconds or so after ignition – continue to represent the most toxic segment of the engine operating cycle.
What does a powertrain code mean?
Powertrain (P-codes) category covers functions that include engine, transmission and associated drivetrain accessories. Network & Vehicle Integration (U-codes) category covers functions that are shared among computers and systems on the vehicle.
How can I reduce my cold start emissions?
Ando et al. [68] suggested that electrically heating up the converter before or after engine cold start-up can reduce cold start emissions.
Does disconnecting the battery reset the ECU?
A. It depends on the car’s age and type of ECU used. On some older cars, disconnecting the battery will reset the system but in most new cars it does nothing, except potentially reset the clock and radio station presets.
