B0221 Toyota Gaia OBD Code

OBD/2 B0221 error code description and symptoms.

The Throttle Position sensor signals the Engine Control Module as to the current position of the engine throttle valve.
The current throttle valve opening is based on the driver's input from the gas pedal. The ECM uses the information from this sensor to help calculate fuel delivery and spark timing.

To check for an open circuit, trace along the length of the transmission control circuit, checking for breaks in the wiring. Repair any broken wiring and make sure all connectors are fully seated and locked.Pay close attention to connectors, looking for corrosion, bent or broken pins, or moisture in the connector. Repair any connector issues even if they are not specifically part of the transmission control circuit as they may serve a function in providing power to the transmission control circuit.

B0221 Toyota Gaia Error Code Repair Process :

If your vehicle failed a B0221 test and the B0221 Check Engine Light is NOT on, chances are you have a problem with the OBDII system, a burned out MIL lamp, or a faulty catalytic converter. The converter is essentially an afterburner that cleans up the exhaust after it exits the engine. The OBDII system uses catalyst temperature sensor low input (bank 2) a ownstream oxygen sensor to monitor the efficiency of the converter, and it should detect a drop in converter efficiency if the converter has been contaminated or is failing (ignition misfiring, leaky exhaust valves, and oil burning can all damage the converter). What you want to look catalyst temperature sensor low input (bank 2): Any conditions that might cause ignition misfire, an overly rich or lean fuel condition, or loss of compression. Use your OBD Express DIY to look at the oxygen sensor outputs, coolant temperature, airflow, calculated engine load, and inlet air temperature.

Common Causes of Toyota Gaia B0221 OBD2 Code

A common cause of code B0221 is the failure of Catalyst Temperature Sensor Low Input (Bank 2), but there are several other possible causes as well, such as ;

Damaged ECM
Air fuel ratio (A/F) Sensor 1 Bank 1 harness is open or shorted
Exhaust tube
Oil flow restriction in the oil passages or the variable camshaft timing (VCT) valve body
