The speed sensor detects wheel speed and sends the appropriate signals to the skid control ECU. These signals are used for the ABS control system. This speed sensor contains a sensor IC, which consists of 2 MREs (Magnetic Resistance Element). The speed sensor rotor, which consists of 48 sets of N and S poles that are arranged in a circle, is integrated with the inner race of the hub bearing.

If a trouble code is displayed during the DTC check, check the circuit indicated by the DTC. For details of each code, refer to the page for the respective "DTC No." in the DTC chart. Inspect the fuse and relay before investigating the trouble areas as shown in the table below.

If there are no DTCs output and the problem still occurs, check the circuits for each problem symptom in the order given in the table below and proceed to the relevant troubleshooting page.

If a normal code is displayed during the diagnostic trouble code check although the trouble still occurs, check the electrical circuits for each symptom in the order given in the charts on the following pages and proceed to the page given for troubleshooting.

Description The newly developed 4GR-FSE D-4 (Direct injection 4-stroke gasoline engine) is a 2.5-liter, 24-valve DOHC V6 engine. This engine uses a Direct injection system, Dual VVT-i (Variable Valve Timing-intelligent) system, DIS (Direct Ignition System), ACIS (Acoustic Control Induction System), Electronic SCV (Swirl Control Valve) and ETCS-i (Electronic Throttle Control System-intelligent). These control functions achieve improved engine performance, fuel economy, and clean emissions.

The engine control unit and the transmission control unit are located inside the ECM. The engine control unit intercommunicates with the transmission control ECU with the Controller Area Network (CAN). If there is a problem in this intercommunication, the ECM sets a DTC.  

DTC P2A00 indicates malfunctions related to the bank 1 A/F sensor. DTC P2A03 indicates malfunctions related to the bank 2 A/F sensor. Bank 1 refers to the bank that includes cylinder No. 1. Bank 2 refers to the bank that includes cylinder No. 2. Sensor 1 refers to the sensor mounted in front of the Three-Way Catalytic Converter (TWC) and located near the engine assembly.
