P0132 Component Inspection upper-limit spec says "voltage never exceeds 1.0V" (matches P0131 page EF & EC-7108).

Continued from EF & EC-7112

CG10, CGA3

Diagnostic Procedure (Cont'd)

Step 3 — CHECK HEATED OXYGEN SENSOR 1 (FRONT)

1
Refer to "Component Inspection", below.
2
OK or NG: - OK → GO TO 4. - NG → Replace heated oxygen sensor 1 (front).

Step 4 — CHECK INTERMITTENT INCIDENT

1
Perform "TROUBLE DIAGNOSIS FOR INTERMITTENT INCIDENT", EC-7070.
2
→ INSPECTION END.

Component Inspection

HEATED OXYGEN SENSOR 1 (FRONT)

With CONSULT-II

1
Start engine and warm it up to normal operating temperature.
2
Select "MANU TRIG" and "HI SPEED" in "DATA MONITOR" mode, and select "HO2S1 (B1)" and "HO2S1 MNTR (B1)".
3
Hold engine speed at 2,000 rpm under no load during the following steps.
4
Touch "RECORD" on CONSULT-II screen.
5
Check the following. - "HO2S1 MNTR (B1)" in "DATA MONITOR" mode changes from "RICH" to "LEAN" to "RICH" 3 times in 10 seconds. 3 times (cycles) are counted as shown below: R = "HO2S1 MNTR (B1)", "RICH" L = "HO2S1 MNTR (B1)", "LEAN" - "HO2S1 (B1)" voltage goes above 0.6V at least once. - "HO2S1 (B1)" voltage goes below 0.3V at least once. - "HO2S1 (B1)" voltage never exceeds 1.0V.

CAUTION

Discard any heated oxygen sensor which has been dropped from a height of more than 0.5 m (19.7 in) onto a hard surface such as a concrete floor; use a new one.
