DIAGNOSTIC TROUBLE CODE (DTC) – P0341 CAMSHAFT POSITION SENSOR
RATIONALITY
Circuit Description
The Camshaft Position Sensor is used to detect Cam-
shaft position and to have correlation with Crankshaft
position so that the ECM can determine which cylinder is
ready to be fueled by the injector. The polarity of cam-
shaft sensor signal must be changed only once per
crankshaft position.
Conditions for Setting the DTC
Engine is running.
No traction of CMP signal between teeth 18 and 82
but change in polarity.
Action Taken When the DTC Sets
The Malfunction Indicator Lamp (MIL) will illuminate.
The ECM will record operating conditions at the time
the diagnostic fails. This information will be stored in
the Freeze Frame and Failure Records buffers.
A history DTC is stored.
Conditions for Clearing the MIL/DTC
The MIL will turn off after four consecutive ignition
cycles in which the diagnostic runs without a fault.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
Check and correct any abnormal engine noise before
using the diagnostic table.
Any circuitry that is suspected as causing engine noise
complaint should be thoroughly checked for the follow-
ing conditions :
Backed-out terminals.
Improper mating.
Broken locks.
Improperly formed.
Damaged terminals.
Poor terminal-to-wire connections.
Physical damage to the wiring harness.

Circuit Description
The wheel speed sensor is used to detecting the road
situation.
As the wheel is rotated, the wheel speed sensor pro-
duces an AC voltage that increase with wheel speed.
The EBCM uses the frequency of the AC signal to calcu-
late wheel speed. The wheel speed sensor is connected
to EBCM by a “twisted pair” of wires. Twisting reduces
noise susceptibility than may cause a DTC to se.If the
wheel speed sensor detects a rough road condition, the
ECM misfire detection diagnostic will be de-activated.

DIAGNOSTIC TROUBLE CODE (DTC) – P0420 CATALYST LOW EFFICIENCY
Circuit Description
In order to control exhaust emissions of Hydrocarbons
(HC), Carbon Monoxide (CO) and Nitrogen Oxide
(NOx), a Three-Way Catalytic Converter (TWC) is used.
The catalyst within the converter promotes a chemical
reaction which oxidizes the HC and CO present in the
exhaust gas, converting them into harmless water vapor
and carbon dioxide, it also reduces NOx, converting it
into nitrogen. The catalytic converter also has the ability
to store oxygen. The Engine Control Module (ECM) has
the capability to monitor this process using a Heated
Oxygen Sensor (HO2S) located in the exhaust stream
past the TWC. The HO2S produces an output signal
which indicates the oxygen storage capacity of the cata-
lyst; this in turn indicates the catalyst’s ability to convert
exhaust emissions effectively. The ECM monitors the
catalyst efficiency by first allowing the catalyst to heat
up, waiting for a stabilization period while the engine is
idling, and then adding and removing fuel while monitor-
ing the reaction of the HO2S. When the catalyst is func-
tioning properly, the HO2S response to the extra fuel is
slow compared to the Oxygen Sensor (O2S). When the
HO2S response is close to that of the O2S, the Oxygen
storage capability or efficiency of the catalyst is consid-
ered to be bad, and the Malfunction Indicator Lamp
(MIL) will illuminate.
Conditions for Setting the DTC
Oxygen Sensor Capacity test condition:
Closed loop stoichiometry.
Engine is running more than 300 seconds.
Airflow is between 25~50kg/h.
Engine Coolant Temperature (ECT) is more than
70°C(176°F) .
Engine speed between 2,400rpm and 3,000rpm.
Vehicle speed is between 64km/h(28.6mph) and
80km/h(49.7mph).
Note: Test is aborted for this idle if:
Change in engine speed is greater than 80 rpm.
A/C status changed.
Cooling fan status changed.Insufficient air/fuel shift.

cycles in which the diagnostic runs without a fault.
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
The catalyst test may abort due to a change in the en-
gine load. Do not change the engine load (i.e. A/C, cool-
ant fan, heater motor) while a catalyst test is in progress.
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 intermit-
tent complaint, should be thoroughly checked for the fol-
lowing conditions:
Backed-out terminals
Improper mating
Broken locks
Improperly formed
Damaged terminals
Poor terminal-to-wire connection.

DIAGNOSTIC TROUBLE CODE (DTC) – P0444 EVAP PURGE CONTROL
CIRCUIT NO SIGNAL
Circuit Description
The evaporative emission (EVAP) system includes the
following components :
Fuel tank.
EVAP vent solenoid.
Fuel pipes and hoses.
Fuel vapor lines.
Fuel cap.
EVAP canister.
Purge lines.
EVAP canister purge valve.
EVAP service port.
The evaporative emission system is checked by apply-
ing vacuum to the EVAP system and monitoring for a
vacuum decay. The engine control module(ECM) moni-
tors the vacuum level through the fuel tank pressure
sensor signal. At the appropriate time, the EVAP canis-
ter purge valve and the EVAP vent solenoid are turned
on, allowing the engine to draw a small vacuum on the
entire EVAP system. After the desired vacuum level has
been achieved, the EVAP canister purge valve is turned
OFF, sealing the system. If a sufficient vacuum level
cannot be achieved, a large leak is indicated. This can
be caused by the following conditions :
Missing or faulty fuel cap.
Disconnected or faulty fuel tank pressure sensor.
Disconnected, damaged, pinched, or blocked EVAP
purge line.
Disconnected or faulty EVAP canister purge valve.
Disconnected or faulty EVAP vent solenoid.Open ignition feed circuit to the EVAP vent or purge so-
lenoid.
Damaged EVAP canister.
Leaking fuel sensor assembly O-ring.
Leaking fuel tank or fuel filler beck.
Any of the above conditions can set DTC P0444.
The test is failed if the tank vacuum is less than 10 in
H20 for 15 seconds and the manifold vacuum integral is
greater than 49512 (proportional to purge mass from the
tank).
Conditions for Setting the DTC

DIAGNOSTIC TROUBLE CODE (DTC) – P0462 FUEL LEVEL SENSOR LOW
V O LTA G E
Circuit Description
The engine control module(ECM) uses the fuel level in-
put from the Fuel Level Sensor to calculate expected va-
por pressures within the fuel system. Vapor pressure
vary as the fuel level changes. Vapor pressure is critical
in determining if the evaporative emission (EVAP) sys-
tem is operating properly. Fuel Level is also used to de-
termine if the Fuel level is too high or too low to be able
to accurately detect EVAP system faults. This Diagnos-
tic Trouble Code(DTC) detects a stuck fuel level sender.
Conditions for Setting the DTC
Fuel Level Sensor voltage is less than 0.05V.
Fuel Level Sensor circuit low voltage.
Action Taken When The DTCs Sets
The Malfunction Indicator Lamp (MIL) will not illumi-
nate.
The ECM will store conditions which were present
when the DTC was set as Failure Records data only.
This information will not be stored in the Freeze
Frame data.Conditions for Clearing the MIL/DTC
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
Inspect harness connectors for backed-out terminal, im-
proper mating, broken locks, improperly formed or dam-
aged terminals, and poor terminal-to-wire connection.
Inspect the wiring harness for damage.
A stuck Fuel Level Sensor may cause the DTC to set. If
DTC P0463 cannot be duplicated, the information in-
cluded in the Freeze Frame data can be useful in deter-
mining vehicle operating conditions when the DTC was
first set.
Resistance check for the Fuel Level Sensor.
Empty = 100 ohms or over.
Half full = about 32.5 ohms.
Full = 10 ohms or less.
