- A) there are no extraneous sounds coming from the engine (knocks, rattle), indicating cranking of the connecting rod or main bearings or a malfunction of the oil pump;
- b) the engine is filled with oil in accordance with the factory operating instructions;
- V) the oil level in the engine crankcase is correct (see "Lubrication system - oil level check");
- G) the oil pressure sensor is working and its wire is not shorted to "mass". We check the integrity of the sensor wire insulation visually. To check the sensor itself, we replace it with a known good one and start the engine. If the control lamp continues to burn, then the sensor is working.
Checking the oil pressure in the engine with a tool
You will need a pressure gauge to do the job (see "Tools, fixtures and operating materials").
1. On engines 2112, 21124 and 21114 remove engine trim (see "Decorative overlay of the engine - removal and installation").
2. Loosen the tightening with a socket wrench by 21 mm, unscrew the emergency oil pressure sensor (shown on 16 valve engine).
Note. On an 8-valve engine, the operation is as follows:
3. We wrap the pressure gauge tip into the sensor seat.
4. We start the engine and check the oil pressure. For a serviceable engine warmed up to operating temperature, the oil pressure at idle speed must be at least 200 kPa (2.0 kgf/cm²).
If the pressure is lower, the engine needs to be repaired.
