April 5, 2026: LEMON Manuals is launched! Read the announcement.

Component Inspection

OTS Simulation Inspect
1. IG KEY OFF
2. Disconnect OTS connector.
3. IG KEY ON
4. Perform voltage simulation to signal circuit of OTS.

5. Does the simulation frequency make AAT value change?
  YES
  - Go to next step as below
  NO
  - Substitute with a known-good OTS and check for proper operation. If the problem is corrected, replace OTS and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.

Resistance Inspection

Ignition "OFF"

Measure resistance between power terminal and control terminal of the sensor connector (Component side)

Specification

Is resistance within the specification?
YES
- Check for poor connection between ECM and component: backed out terminal, improper mating, broken locks or poor terminal to wire connection. Repair as necessary and go to "VERIFICATION OF VEHICLE REPAIR " procedure
NO
- Substitute with a known - good RCV and check for proper operation.
  If the problem is corrected, replace RCV and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
