2. INSPECT NO. 2 ELECTRONIC FUEL INJECTION MAIN RELAY (EFI-MAIN NO. 2)
| (a) Measure the resistance according to the value(s) in the table below. Standard Resistance:
If the result is not as specified, replace the No. 2 electronic fuel injection main relay (EFI-MAIN NO. 2). |
|
3. INSPECT AIR FUEL RATIO SENSOR HEATER RELAY (EFI-MAIN NO. 3)
| (a) Measure the resistance according to the value(s) in the table below. Standard Resistance:
If the result is not as specified, replace the air fuel ratio sensor heater relay (EFI-MAIN NO. 3). |
|
4. INSPECT EFI INJECTION RELAY (D INJ)
| (a) Measure the resistance according to the value(s) in the table below. Standard Resistance:
If the result is not as specified, replace the EFI injector relay (D INJ). |
|
5. INSPECT NO. 2 IGNITION RELAY (IG2 NO. 1)

Camshaft Position "B" - Actuator Bank 1 Circuit Open (P001313,P002313)
DESCRIPTION The Variable Valve Timing (VVT) system adjusts the exhaust valve timing to improve driveability. The engine oil pressure turns the VVT controller to adjust the valve timing.
The cam timing oil control solenoid assembly operates according to signals received from the ECM to control the
ECM Power Source Circuit
DESCRIPTION When the engine switch is turned on (IG), the battery voltage is applied to the IGSW terminal of the ECM.
The output signal from the MREL terminal of the ECM causes a current to flow to the coil of the EFI-MAIN NO. 1 relay, closing the contacts and supplying power to terminals +B and +
