Trouble Code: P0139
O2 (B1 S2) Slow Response
Trouble
Code Conditions:Engine started; vehicle driven at 20-55 mph with the
throttle open for 2 minutes; ECT at more than 158ºF (70C); catalytic
converter temperature is more than 1112F (600C); and EVAP purge is
active. O2 Sensor signal voltage switches less than 16 times from lean
to rich within 20 seconds during monitoring, or will compare the state
of change between the front and rear O2 Sensors and if the differences
are greater than a calibrated amount, the DTC will set. 3 good trips
are required to turn off the MIL.
Possible Causes:
Trouble Code: P0344
Camshaft Position Sensor Circuit Intermittent
Trouble
Code Conditions:Engine cranking or running; system voltage over 10.5v.
The PCM detected an intermittent loss of the CMP Sensor signal during
the period of 2.5 complete engine revolutions. The failure counter must
reach 20 before this code matures and a code is set.
Possible Causes:
Good luck....
No Camshaft Position Sensor Circuit Failure
Trouble
Code Conditions:Engine cranking or running, system voltage over 10v.
The PCM detected CKP pulses without detecting any CMP Sensor pulses for
5 seconds or 2.5 engine revolutions.
