The process for cylinder identification with an intake manifold pressure pulsation waveform is: Retard the engine cycle reference points from the secondary ignition events: they should be between 20 and 35 degrees afterward. As a rule of thumb, place Phase rulers at “30/720 x the time between two consecutive ignition events” after each.
9. Compare Inlet Manifold Pressure (IMP) value with the barometric pressure value. Are the values within 10.3 kPa (1.5 psi) of each other? a. Yes; Go to step 12. b. No; Go to step 10. 10. Disconnect the intake pressure/temperature sensor. 11. Inspect the intake pressure/temperature sensor and wiring connector for signs of damaged, bent, spread
2. Gray/red stripe - intake air volume control signal (ECU connector C, pin 8) 3. Yellow/green stripe - IAT sensor control signal (ECU connector C, pin 21) 4. Brown/black stripe - common circuit tied with oil temp sensor, EGR temp sensor, engine coolant temp sensor, throttle position sensor, and vapor pressure sensor 5.
