Fig. 49: Camshaft Position (CMP) Sensor A Circuit Diagram 

General Description 

Camshaft position (CMP) sensor A detects the intake camshaft timing and sends pulsing signals to the engine 
control module (ECM)/powertrain control module (PCM). The ECM/PCM determines the advance or the retard 
of the camshaft timing according to the signals from the crankshaft position (CKP) sensor and CMP sensor A. If 
the number of pulsing signals from CMP sensor A during intervals between the CKP standard pulses is more or 
less than the proper number, a malfunction is detected and a DTC is stored.

Malfunction Threshold 

More or less than CMP sensor A pulses is detected during intervals between the CKP standard pulses at least 30 
times. 

Diagnosis Details

When a malfunction is detected, the MIL comes on and the DTC and the freeze frame data are stored in the 
ECM/PCM memory.

Conditions for clearing the MIL 

The MIL will be cleared if the malfunction does not recur during three consecutive trips in which the diagnostic 
runs. 

The MIL, the DTC, and the freeze frame data can be cleared by using the scan tool Clear command or by 
disconnecting the battery. 

DTC P0369 (8): ADVANCED DIAGNOSTICS 

DTC P0369: CAMSHAFT POSITION (CMP) SENSOR B CIRCUIT INTERMITTENT 
INTERRUPTION 

Fig. 50: Camshaft Position Sensor B Circuit Diagram 

General Description 

The camshaft position (CMP) sensor B consists of a rotor and a semiconductor that detects rotor position. When 
the rotor turns after starting the engine, the changes of magnetic flux in the semiconductor are converted into 
pulsing signals to the engine control module (ECM)/powertrain control module (PCM). The CMP sensor B 
detects the top dead center of each cylinder for fuel injection timing. 

If CMP sensor B pulsing signals are detected an abnormal number of times due to noise, a malfunction is 
detected and a DTC is stored.

Fig. 51: Secondary HO2S Output - Graph 

General Description 

The three way catalytic converter (TWC) converts hydrocarbons (HC), carbon monoxide (CO), and oxides of 
nitrogen (NOx) in the exhaust gas to water vapor, carbon dioxide (CO2), and dinitrogen (N2). 

The TWC efficiency does not depend entirely on engine conditions or the deterioration level of the TWC. It can 
be optimized by stabilizing the secondary HO2S output. 

If the TWC deteriorates, the air/fuel ratio downstream of the TWC (the secondary HO2S output) often differs 
from the target secondary HO2S output, and the status is represented by the parameter (SIGSQRLS). 

Therefore, if the SIGSQRLS exceeds a specified value for a set time, a malfunction is detected and a DTC is 
stored.
