Eli auto nykii ja yskii. Vika koodit oli P0303, P0320, P1151 ja P1152. No selitykset koodeille ilmeisesti läysin.
P0303 Cylinder #3 Misfire Detected
P0320 Ignition Engine Speed Input Circuit Malfunction
P1151 Lack Of HO2S21 Switch - Sensor Indicates Lean
P1152 Lack Of HO2S21 Switch - Sensor Indicates Rich

Eli voisko joku kertoo mikä voorttia vaivaa, kiitos.

En tiedä auttaako mitään, mutta jotain vikakoodien lisäselostuksia löytyi?:

P0320
Ignition Engine Speed Input Circuit Malfunction The ignition engine speed sensor input signal to PCM is continuously monitored. The test fails when the signal indicates that two successive erratic profile ignition pickup (PIP) pulses have occurred. Loose wires/connectors. Arcing secondary ignition components (coil, wires and plugs) On board transmitter (2-way radio) The DTC indicates that two successive erratic PIP pulses occurred.

P1151
Lack of HO2S-21 Switch, Sensor Indicates Lean A HEGO sensor indicating lean at the end of a test is trying to correct for an over-rich condition. The test fails when fuel control system no longer detects switching for a calibrated amount of time. See Possible Causes for DTC P1130

P1152
Lack of HO2S-21 Switch, Sensor Indicates Rich A HEGO sensor indicating rich at the end of a test is trying to correct for an over-lean condition. The test fails when the fuel control system no longer detects switching for a calibrated amount of time. See Possible Causes for DTC P1130

Eli ainaki lambda on menny ääripäille koittaessaan säätää seosta sen vaikuttamatta lambda-arvoihin, mutta se ei tarkota aina että se olis rikki, vaan muukin voi vääristää sitä.. (pakoputki tukossa, kampikammion huohotusventtiili)
