Protege DX L4-1.6L DOHC (2000)
Specifications:
RPM PID: 650 - 750 RPM
FREQUENCY: 16 - 18 Hz
18. Press LEVEL key to change the threshold voltage to 6VOLT.
19. Make sure that the FREQUENCY indicates 0 Hz.
-
If FREQUENCY value or PCM terminal 85 voltage are out of specifications, carry out the "Circuit Open/Short Inspection".
Circuit Open/Short Inspection
1. Remove the PCM.
2. Connect the SST (104 Pin Breakout Box) to the PCM as shown.
3. Tighten the connector attaching screw.
Tightening torque:
7.9 - 10.7 N.m {80 - 110 kgf.cm, 69.5 - 95.4 in.lbf}
4. Inspect for an open or short circuit in the following wiring harnesses by probing the applicable sensor and SST (104 Pin Breakout Box) terminals
with ohmmeter leads.
-
If there is an open or short circuit, repair or replace wiring harnesses.
-
If there is no open or short circuit, replace the CMP sensor.
Open circuit
-
CMP signal circuit (CMP sensor connector terminal B and PCM connector terminal 85)
-
Power circuit (CMP sensor connector terminal A and main relay terminal D through common connector)
-
GND circuit (CMP sensor connector terminal C and PCM connector terminal 103)
Short circuit
-
CMP signal circuit (CMP sensor connector terminal B and PCM connector terminal 85 to GND)
-
Power circuit (CMP sensor connector terminal A and main relay terminal D through common connector to GND)
5. Reconnect the CMP sensor connector.
6. Inspect the camshaft pulley (exhaust side) for damage and cracks.
