On-vehicle InspectionCatalyst System Efficiency Below Threshold (Bank 1) (P0420)
MONITOR DESCRIPTION
The ECM uses sensors mounted in front of and behind the Three-Way Catalytic Converter
(TWC) to monitor its efficiency.
The first sensor, the air fuel ratio sensor, sends pre-catalyst information to
the ECM. The second sensor, the heat ...

HINT:
Using the Techstream to read the Data List allows the values or states of switches,
sensors, actuators and other items to be read without removing any parts. This non-intrusive
inspection can be very useful bec ...
Input / Turbine Speed Sensor Circuit Malfunction (P0715,P0717)
DESCRIPTION
This sensor detects the rotation speed of the turbine which shows the input revolution
(speed) of the transaxle. By comparing the input turbine speed signal (NT) with
the counter gear speed sensor signal (NC), the TCM detects the shift timing ...
