Component Description

UBS00D6B

The camshaft position sensor is a basic component of the engine
control system. It monitors engine speed and piston position. These
input signals to the engine control system are used to control fuel
injection, ignition timing and other functions.
The camshaft position sensor has a rotor plate and a wave-forming
circuit. The rotor plate has 360 slits for a 1

° (POS) signal and 4 slits

for a 180

° (REF) signal. The wave-forming circuit consists of Light

Emitting Diodes (LED) and photo diodes.
The rotor plate is positioned between the LED and the photo diode.
The LED transmits light to the photo diode. As the rotor plate turns,
the slits cut the light to generate rough-shaped pulses. These pulses
are converted into on-off signals by the wave-forming circuit and
sent to the ECM.
The distributor is not repairable and must be replaced as an assem-
bly except distributor cap and rotor head.

Possible Cause

P0340

Camshaft position sensor 
circuit

A)

Either 1

° or 180° signal is not sent to ECM 

for the first few seconds during engine 
cranking.

●

Harness or connectors
(The camshaft position sensor circuit is 
open or shorted.)

●

Camshaft position sensor

●

Starter motor (Refer to 

SC-9

 .)

●

Starting system circuit (Refer to 

SC-9

 .)

●

Dead (Weak) battery

B)

Either 1

° or 180° signal is not sent to ECM 

often enough while the engine speed is 
higher than the specified engine speed.

C)

The relation between 1

° and 180° signal is 

not in the normal range during the speci-
fied engine speed.

DTC Confirmation Procedure

UBS00D6D

Perform “Procedure for malfunction A” first. If DTC cannot be confirmed, perform “Procedure for mal-
function B and C”.

NOTE:
If “DTC Confirmation Procedure” has been previously conducted, always turn ignition switch OFF and wait at
least 5 seconds before conducting the next test.
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is more than 10.5V.

PROCEDURE FOR MALFUNCTION A

 With CONSULT-II

1.

Turn ignition switch ON.

2.

Select “DATA MONITOR” mode with CONSULT-II.

3.

Crank engine for at least 2 seconds.

4.

If 1st trip DTC is detected, go to 

EC-273, "Diagnostic Procedure"

.

 With GST

Follow the procedure “With CONSULT-II”.

PROCEDURE FOR MALFUNCTION B AND C

 With CONSULT-II

1.

Turn ignition switch ON.

2.

Select “DATA MONITOR” mode with CONSULT-II.

3.

Start engine and run it for at least 2 seconds at idle speed.

4.

If 1st trip DTC is detected, go to 

EC-273, "Diagnostic Procedure"

.

 With GST

Follow the procedure “With CONSULT-II”.
