Dtc P0341 Camshaft Position (Cam) Sensor Rationality - Daewoo CIELO EURO III Manual

A history DTC will clear after 40 consecutive warm up
cycles without a fault.
DTC(s) can be cleared by using the scan tool.
Diagnostic Aids
An intermittent problem may be caused by a poor con-
nection, rubbed-through wire insulation, or a wire that is
broken inside the insulation.
Any circuitry, that is suspected as causing the com-
plaint, should be thoroughly checked for the following
conditions:
Backed-out terminals
Improper mating
Broken locks
Improperly formed
Damaged terminals
Poor terminal-to-wire connection
Physical damage to the wiring harness
Anytime a poor connection is present, the CMP Refer-
ence Activity counter will stop incrementing.

DTC P0341 Camshaft Position (CAM) Sensor Rationality

Step
Perform an On-Board Diagnostic (EOBD) System
Check.
1
Is the system check complete?
1. Turn the ignition ON, with the engine OFF.
2. Install a scan tool.
2
3. Operate the vehicle within the Freeze Frame
conditions for setting the DTC as noted.
Is Diagnostic Trouble Code (DTC) P0341 set?
1. Turn the ignition OFF.
2. Disconnect the Camshaft Position (CMP) sensor
electrical connector.
3. Turn the ignition ON, with the engine OFF.
3
4. Using a Digital Voltmeter (DVM), check the
voltage between the CMP harness connector
(Engine Control
Module [ECM] side) terminal A and ground.
Does the DVM indicate near the specified value?
Using a DVM, check the voltage between the CMP
sensor wiring harness connector terminal C and
4
ground.
Is the DVM indicate over the specified value?
With a test light connected to ground, probe the
CMP harness connector terminal A.
5
Does the test light illuminate?
With a test light connected to B+, probe the CMP
harness connector terminal B.
6
Does the test light illuminate?

Test Description
Number(s) below refer to the step number(s) on the
Diagnostic Table.
1. The On-Board Diagnostic (EOBD) System Check
prompts the technician to complete some basic
checks and store the freeze frame and failure re-
cords data on the scan tool if applicable. This
creates an electronic copy of the data taken when
the malfunction occurred. The information is then
stored on the scan tool for later reference.
2. This step determines if DTC P0341 is the result of a
hard failure or an intermittent condition.
3. This step checks for a voltage supplied by the
ECM to the CMP.
A poor connection in any of the circuits at the CMP
will cause the CMP Active Counter will stop incre-
menting.
14. The replacement ECM must be repro-
grammed.
Refer to the latest Techline Procedure for ECM
reprograming.
