Nissan Almera Tino V10. Manual — part 344
EC-202
[QG (WITH EURO-OBD)]
DTC P0132, P0152 HO2S1 (A/T MODELS)
Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.

Diagnostic Procedure
EBS00QJM
1.
RETIGHTEN HEATED OXYGEN SENSOR 1
1.
Turn ignition switch “OFF”.
2.
Loosen and retighten corresponding heated oxygen sensor 1.
>> GO TO 2.
2.
CHECK HO2S1 GROUND CIRCUIT FOR OPEN AND SHORT
1.
Disconnect heated oxygen sensor 1 harness connector.
2.
Disconnect ECM harness connector.
3.
