METER / GAUGE SYSTEM - Oil Pressure Gauge Malfunction
DESCRIPTION
The oil pressure sender detects the oil pressure generated when the engine is started. The combination meter determines that the engine is running when the engine speed is 400 rpm or more, and determines that the engine is cranking when the engine speed is 200 rpm or less. The oil pressure receiver gauge detects and indicates the oil pressure applied to the oil pressure sender.

| 3.INSPECT OIL PRESSURE GAUGE ASSEMBLY (OIL PRESSURE SENSOR) |
Check that the needle moves in accordance with the engine speed.
- OK:
- Needle is as shown in illustration when engine is stopped.
Needle moves when engine is running.
Result| Result | Proceed to |
| Oil pressure receiver gauge operates correctly according to engine condition | A |
| Oil pressure receiver gauge does not operate correctly according to engine condition (for 1GR-FE) | B |
| Oil pressure receiver gauge does not operate correctly according to engine condition (for 1UR-FE) | C |
| Oil pressure receiver gauge does not operate correctly according to engine condition (for 3UR-FE) | D |
| Oil pressure receiver gauge does not operate correctly according to engine condition (for 1VD-FTV) | E |

| 4.CHECK HARNESS AND CONNECTOR (COMBINATION METER - OIL PRESSURE SENSOR) |
for 1UR-FE, 3UZ-FE, 1VD-FTV:
Disconnect the E8 meter connector.
Disconnect the D18 gauge connector.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
| Tester Connection | Condition | Specified Condition |
| E8-11 (S) - D18-1 (S) | Always | Below 1 Ω |
| E8-11 (S) or D18-1 (S) - Body ground | Always | 10 kΩ or higher |
for 1GR-FE:
Disconnect the E8 meter connector.
Disconnect the C33 gauge connector.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
| Tester Connection | Condition | Specified Condition |
| E8-16 (S) - C33-2 (VOUT) | Always | Below 1 Ω |
| E8-17 (IG+) - C33-3 (VC) |
| E8-24 (E) - C33-1 (GND) |
| E8-16 (S) or C33-2 (VOUT) - Body ground | Always | 10 kΩ or higher |
| E8-17 (IG+) or C33-3 (VC) - Body ground |
Result| Result | Proceed to |
| NG | A |
| OK (w/ Multi-information Display) | B |
| OK (w/o Multi-information Display) | C |
