Toyota Camry (XV70): Terminals Of Ecm
TERMINALS OF ECM
HINT:
The standard normal voltage and resistance between each pair of ECM terminals is shown in the table below. The appropriate conditions for checking each pair of terminals are also indicated. The result of checks should be compared with the standard normal voltage and resistance for that pair of terminals, displayed in the Specified Condition column. The illustration above can be used as a reference to identify the ECM terminal locations.

DESCRIPTION The D-4S system has two injection systems. One is an in-cylinder direct injection system that directly injects pressurized fuel into the combustion chamber. The other is an intake port injection system. The ECM determines the percentage of direct injection and port injection necessary in
Inspection
INSPECTION PROCEDURE 1. INSPECT MASS AIR FLOW METER SUB-ASSEMBLY
(a) Perform a visual check for any foreign matter on the intake air temperature sensor (thermistor) of the mass air flow meter sub-assembly shown in the illustration.
OK: There is no foreign matter. If the result is not as sp
