1 |
Special tool Tester knob indication
continuity test ( Ecm couplers (harness side) Is the continuity ok? |
Go to step 2. | Bl, y, g or br wire open |

Special tool
Tester knob indication resistance (Ω) Isc valve continuity ∞Ω¶ (infinity) (terminal . Ground)
Isc valve resistance approx. 80 Ω at 20 °c (68 °f) (terminal: “a” – terminal: “b”, terminal: “c” – terminal: “d”) Is the resistance ok? |
If wire is ok, intermittent trouble or faulty ecm. | Replace the isc valve with a new one. Refer to “throttle body removal and installation” in section 1d (page 1d- 10). |
Active control inspection (isc rpm control)
Check 1
Check 2
Check 3
Check 4
Note be careful not to increase the “spec” to 2 000 rpm, or the “engine speed” may reach the upper limit. |
If the isc valve does not function properly, inspect the isc valve or replace the isc valve. Refer to “dtc “c40” (p0505 / p0506 / p0507): isc valve circuit malfunction” or “throttle body disassembly and assembly” in section 1d .
