The Toyota Picnic is a compact MPV (multi-purpose vehicle) that was produced by Toyota from 1996 to 2009. The Picnic was sold in various markets around the world, including Japan, Europe, and Asia.
The Toyota Picnic is equipped with a variety of engines, including gasoline and diesel engines. The most common engine used in the Picnic is a 2.0-liter gasoline engine. This engine is equipped with a catalytic converter, which is a device that helps to reduce emissions from the vehicle.
The catalytic converter in the Toyota Picnic is monitored by a series of sensors, including an oxygen sensor. The oxygen sensor measures the amount of oxygen in the exhaust gases from the engine. If the oxygen sensor detects that there is too much oxygen in the exhaust gases, it will send a signal to the engine control unit (ECU). The ECU will then turn on the check engine light and store a fault code in the vehicle's memory.
Fault code P1420 is a generic OBD-II (On-Board Diagnostics) fault code that indicates that the catalyst system efficiency has fallen below the threshold for Bank 1. Bank 1 is the side of the engine that contains cylinder 1.

- Faulty oxygen sensor
- Exhaust leak
- Engine misfire
- Vacuum leak
Diagnosis of Fault Code P1420
To diagnose fault code P1420, a mechanic will need to perform the following steps:
1. Inspect the catalytic converter for damage or leaks.
2. Inspect the oxygen sensor for damage or contamination.
3. Check for exhaust leaks.
4. Check for engine misfires.
5. Check for vacuum leaks.
Repair of Fault Code P1420
The repair for fault code P1420 will depend on the underlying cause of the problem. In some cases, the catalytic converter may need to be replaced. In other cases, the oxygen sensor or exhaust system may need to be repaired.
