Code No. P0340: Camshaft Position Sensor System
OPERATION
Power is supplied to the camshaft position sensor
(terminal No. 3) from the engine control relay (ter-
minal No. 1) and is earthed to the engine-ECU
(terminal No. 40) from the camshaft position sen-
sor (terminal No. 1).
A power voltage of 5 V is applied to the camshaft
position sensor output terminal (terminal No. 2)
from the engine-ECU (terminal No. 88).
FUNCTION
The camshaft position sensor detects the top
dead center on the compression stroke of the No.
1 cylinder and inputs a pulse signal to the engine-
ECU.

TROUBLE JUDGMENT
Check Condition
After the engine has started up.
Judgment Criterion
The sensor output voltage remains unchanged
(no pulse signal is inputted) for 2 seconds.
PROBABLE CAUSE
Failed camshaft position sensor
Open/short circuit in camshaft position sensor cir-
cuit or loose connector contact
Failed engine-ECU
DIAGNOSIS PROCEDURE
STEP 1. Connector check: B-106 camshaft
position sensor connector
Q: Is the check result normal?
YES :
Go to Step 2 .
NO :
Repair.
STEP 2. Measure voltage at B-106 camshaft
position sensor connector.
Disconnect connector, and measure at harness
side.
Ignition switch: ON
Voltage between terminal No. 3 and earth.
OK: System voltage
Q: Is the check result normal?
YES :
Go to Step 4 .
NO :
Go to Step 3 .
