2.34. The camshaft position sensor fault (fault code P0340)
Serial
number Operation steps Test
results Next step
1 round which is diagnostic instrument, the
ignition switch is in the "ON" Next step
Yes To step 4 2 Dial the joint sensor wire harness, using a
multimeter to check voltage between the 3#
and 2# pins connector on sensor placement
is around 12V.
No Next step
Yes Repair or replace the wire harness 3 Check phase sensor 3# pin and 87# pin of
the main relay whether the circuit breaker or
open ground; between the X1_30# pin
check phase sensor 2# pins with the ECU
whether the circuit breaker.
No Next step
Yes To step 6 4 If the 9.9V about the value of voltage
between the X1_72# pin and the negative
pole of the power supply check phase
sensor connector 1# pin and ECU.
No Next step
Yes Repair or replace the wire harness 5 Between the X1_72# pin check phase
sensor connector 1# pin and the ECU
whether the circuit breaker.
No Next step
Yes Diagnostic aid 6 Check the camshaft signal wheel is intact.
No Replace the signal disc
2.35. A cylinder ignition coil circuit fault (fault code P0351)
Serial
number Operation steps Test
results Next step
1 round which is diagnostic instrument, the
ignition switch is in the "ON" Next step
Yes To step 4 2 Dial the joint on wire harness for ignition
coil, using a multimeter to check voltage
between the 2# pin and the negative pole of
the power supply is 12V.
No Next step
Yes Repair or replace the wire harness 3 Check the ignition coil between the 2# pin
and the 87# pin of main relay circuit is open
circuit or short circuit to ground;
No To step 5
Yes Repair or replace the wire harness 4 Between the X1_4# pin check phase sensor
and papillary 3# pins and ECU line is open
circuit or short circuit to ground.
No Next step
Yes Next step 5 Using a multimeter to check the ignition
coil resistance 2# pin and 3# pin between,
stop should be 0.67 +/-10%
No Replace ignition coil
Yes Diagnostic aid 6 By using the universal resistance between
the table to check the ignition coil 1
cylinder column and ignition anode, stop
should be 9.2K
Ω +/-20%
No Replace ignition coil
