DTC P0340 CMP SENSOR

PFP:22100

Component Description

UBS00DJS

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 ECM 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 6 slits

for a 120

° (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.

NOTE:
The rotor screw which secures the distributor rotor head to the dis-
tributor shaft must be torqued properly.

DTC Confirmation Procedure

UBS00DJU

NOTE:

●

Perform PROCEDURE FOR MALFUNCTION A first. If DTC cannot be confirmed, perform PROCE-
DURE FOR MALFUNCTION B AND C.

●

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 at idle.

PROCEDURE FOR MALFUNCTION A

 With CONSULT-II

1.

Turn ignition switch ON.

Possible cause

P0340

Camshaft position sen-
sor circuit

A)

●

Either 1

° or 120° signal is not sent to ECM 

for the first few seconds during engine 
cranking.

●

Harness or connectors
(The CMP 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 120° 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 120° signal is 

not in the normal range during the specified 
engine speed.
