Oxygen Sensor Heater Inspection
S3RH0A1306016
1) Disconnect sensor connector.
2) Using ohmmeter, measure resistance between
terminals “V
B
” and “GND” of sensor connector.
If found faulty, replace oxygen sensor.
NOTE
Temperature of sensor affects resistance
value largely. Make sure that sensor heater is
at correct temperature.
Resistance of oxygen sensor heater
HO2S-1: 5.0 – 6.4
Ω
at 20
°
C (68
°
F)
HO2S-2: 11.7 – 14.3
Ω
at 20
°
C (68
°
F)
3) Connect sensor connector securely.
Camshaft Position (CMP) Sensor Removal and
Installation
S3RH0A1306018
Removal
1) Disconnect negative cable at battery.
2) Disconnect CMP sensor connector.
3) Remove CMP sensor from timing chain cover.
Installation
1) Check that O-ring is free from damage.
2) Check that CMP sensor and signal rotor teeth are
free from any metal particles and damage.
3) Install CMP sensor to timing chain cover.
Tightening torque
Camshaft position sensor bolt (a): 10 N·m (1.0
kgf-m, 7.5 lb-ft)
4) Connect connector to it securely.
5) Connect negative cable to battery.
Camshaft Position (CMP) Sensor and Its Circuit
Inspection
S3RH0A1306019
1) Confirm that terminal voltages and ground circuit
continuity at CMP sensor connector terminals are in
good condition referring to Step 3 and 5 of “DTC
P0340 (No. 15): Camshaft Position (CMP) Sensor
Circuit Malfunction in Section 1A”.
If not, repair CMP sensor circuit.
If circuits are in good condition, check ECM referring
to “Inspection of ECM and Its Circuits in Section 1A”.
2) Check that CMP sensor signal voltage varies from
low to high or from high to low as specified referring
to Step 6 of “DTC P0340 (No. 15): Camshaft Position
(CMP) Sensor Circuit Malfunction in Section 1A”.
If signal voltage varies as specified, CMP sensor is
in good condition.
If not, replace CMP sensor.
Crankshaft Position (CKP) Sensor Removal and
Installation
S3RH0A1306020
Removal
1) Disconnect negative cable at battery.
2) Remove generator drive belt, loosen pivot bolt and
move generator rearward.
3) Disconnect connector from crankshaft position
sensor.
4) Remove crankshaft position sensor (1) from cylinder
block.
Installation
1) Check to make sure that crankshaft position sensor
and pulley teeth are free from any metal particles
and damage.
2) Install crankshaft position sensor to cylinder block.
