P2242 2006 Toyota Camry Code - Oxygen A/F Sensor Pumping Current Circuit High Bank 2 Sensor 1
Quick Answer
The Air-Fuel ratio (A/F) sensor provides output voltage approximately equal to the existing air-fuel ratio. Common causes include Faulty Air/Fuel Sensor Bank 2, Air/Fuel Sensor Bank 2 harness is open or shorted, Air/Fuel Sensor Bank 2 circuit poor electrical connection. Severity is Moderate - service should be scheduled soon. The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.

Code P2242 2006 Toyota Camry Description
The A/F sensor output voltage is used to provide feedback for the Engine Control Module (ECM) to control the air-fuel ratio.
With the A/F sensor output, the ECM can determine deviation from the stoichiometric air-fuel ratio and control proper injection time. If the A/F sensor is malfunctioning, the ECM is unable to accurately control air-fuel ratio.
The A/F sensor is equipped with a heater which heats the zirconia element. The heater is also controlled by the ECM. When the intake air volume is low (the temperature of the exhaust gas is low), current flows to the heater which heats the sensor to facilitate detection of accurate oxygen concentration.
The A/F sensor is a planar type. Compared to a conventional type, the sensor and heater portions are narrower. Because the heat of the heater is conducted through the alumina to zirconia (of the sensor portion), sensor activation is accelerated.
The code is output when there is an open or short in the A/F sensor circuit, or if A/F sensor output drops. To detect these problems, the voltage of the A/F sensor is monitored when turning the ignition switch to the ON position, and the admittance (admittance is an electrical term that indicates the ease of flow of current) is checked while driving. If the voltage of the A/F sensor is between 0.6 V and 4.5 V, it is considered normal. If the voltage is outside of the specified range, or the admittance is less than the standard value, the ECM will determine that there is a malfunction in the A/F sensor. If the same malfunction is detected in the next driving cycle, the MIL is illuminated and a DTC is set.

Frequently Asked Questions about P2242 2006 Toyota Camry Code
1. What does OBDII code P2242 mean on a 2006 Toyota Camry?
P2242 indicates a high voltage issue in the oxygen air-fuel (A/F) sensor pumping current circuit for Bank 2 Sensor 1.
2. What are the symptoms of code P2242 in a 2006 Toyota Camry?
Symptoms may include poor fuel efficiency, rough idling, hesitation during acceleration, and an illuminated check engine light.
3. What causes code P2242 to appear in a Toyota Camry?
Common causes include a faulty A/F sensor, damaged wiring or connectors, a malfunctioning engine control module (ECM), or exhaust system leaks.
4. How do I diagnose code P2242 on a 2006 Toyota Camry?
Diagnose by inspecting the Bank 2 Sensor 1 wiring and connectors for damage, testing the A/F sensor, and checking for exhaust or intake leaks.
5. What is Bank 2 Sensor 1 on a 2006 Toyota Camry?
Bank 2 refers to the side of the engine opposite Bank 1 (cylinder 2 side), and Sensor 1 is the upstream oxygen/A/F sensor located before the catalytic converter.
6. Can I drive my 2006 Toyota Camry with code P2242?
Driving with P2242 is possible but not recommended, as it can lead to poor performance, increased emissions, and potential damage to the catalytic converter.
7. How do I fix code P2242 on my Toyota Camry?
Repairs may involve replacing the A/F sensor, repairing damaged wiring or connectors, fixing exhaust leaks, or reprogramming the ECM if needed.
8. How much does it cost to repair code P2242 in a Toyota Camry?
Repair costs vary but typically range from $150-$400, depending on whether the A/F sensor or other components need replacement.
9. Can a dirty air filter cause code P2242?
A dirty air filter alone is unlikely to cause P2242 but can contribute to issues affecting the air-fuel mixture, which may exacerbate the problem.
10. Does code P2242 require reprogramming the ECM on a 2006 Toyota Camry?
In rare cases, if the ECM is malfunctioning or has outdated software, reprogramming or replacing the ECM may be necessary.
