Sportster -08 vikakoodit

Viesti Kirjoittaja Pienimeisseli »

Hei
1200 sportster vm-08 antoi seuraavat vikakoodit: p0131, p0154 ja p0562. Ajaessa siis syttyi akunvalo ja moottorivikavalo. Ei vaikuttanut ajoon silloin ainakaan mitään ja koodit nollattua eivät heti syttyneet uudelleenkaan.
Olisinkin tiedustellut osaisiko joku suoriltaan sanoa mistä lähteä vikaa etsimään? Jännitteensäädin rikki? Kiitos.

DTC P0131, P0132, P0134, P0151, P0152, P0154 4.21
GENERAL Oxygen Sensor
See Figure 4-42. The Oxygen (O2) sensor provides a signal to the ECM which indicates whether the engine is running rich or lean.
• A DTC P0131 (front) or P0151 (rear) is set when the ECM detects an excessively lean condition for a specified length of time. DTCs may also set if O2 sensor fails.
• A DTC P0132 (front) or P0152 (rear) is set when the ECM detects an excessively rich condition for a specified length of time. DTCs may also set if O2 sensor fails.
• A DTC P0134 is set when the front O2 sensor circuit is open or sensor is too cold to respond. A DTC P0154 is set when the rear O2 sensor circuit is open or sensor is too cold to respond.
When the air/fuel mixture is ideal, approximately 14.6 parts air to 1 part fuel, the voltage will be approximately 0.45V.
P0131 Front O2 sensor low or engine running lean
P0132 Engine running rich
P0134 Front O2 sensor open/not responding/high
P0151 Rear O2 sensor low or engine running lean
P0152 Engine running rich
P0154 Rear O2 sensor open/not responding/high

DIAGNOSTICS
HD-43876 BREAKOUT BOX
Diagnostic Tips
Diagnostic codes for the O2 sensor may be seen during the vehicle break-in period. The O2 sensor diagnostic codes will not illuminate the check engine lamp for current or historic codes and will only be indicated by Digital Technician or speedometer self diagnostics. If the diagnostic codes are reported during the break-in period, clear or ignore the codes until the break-in period is completed. All historic O2 sensor diagnostic codes are to be ignored and cleared.
The DVOM displays the signal from the O2 sensor in volts. This voltage will have an average value tending towards lean, rich or ideal value depending on operating temperature of the engine, engine speed and throttle position. An open/short to voltage or short to ground in the (PK/O) wire (front) and (PK/GN) wire (rear) will cause the engine to run rich (short to ground) or lean (short to voltage) until fault is detected. Once fault is detected, vehicle will run in open loop.
Check for the following conditions:
• Poor connection. Inspect the ECM harness connector [78], fuel injector connectors [84, 85] and O2 sensor con- nector wiring for backed out terminals, improper mating, broken locks, improperly formed or damaged terminals, poor terminal-to-wire connection and damaged harness.
• Dirty/stuck open injectors. The motorcycle may run lean (dirty/clogged injectors) or rich (stuck open injectors) if there is an injector problem. This could also cause poor fuel economy and performance.
• Loose oxygen sensor. If the O2 sensor is loose, engine performance may be affected. This could also show up as a slow changing O2 sensor voltage.
• Loose/leaking exhaust. This can cause a poor ground connection for sensor or allow fresh air into the exhaust system. If fresh air enters exhaust system, the O2 sensor will read a lean condition, causing the system to go rich.
• Engine misfire. See 4.17 MISFIRE AT IDLE OR UNDER LOAD.
Diagnostic Notes
Each reference number below correlates to a circled number on the flow chart(s).
1. Connect a BREAKOUT BOX (Part No. HD-43876) between EFI wire harness and ECM before measuring voltage. See 4.7 BREAKOUT BOX: EFI.
2. 5 volts is typical for a cold engine. Once the O2 sensors are up to operating temperature, typical voltage is 0.45 volt.
3. See 4.9 INTAKE LEAK TEST.

Ja vielä lisäksi:

DTC DESCRIPTION
P0562 Battery voltage low

Diagnostic Tips
• Low voltage generally indicates a loose wire, corroded
connections
, battery and/or a charging system problem.


Tää on puhdasta arvailua, mutta noiden vikakoodien perusteella itse tarkistaisin ainakin akun kaapelit ja niiden kiinnitykset, maajohdon murtuminenhan on kait melko tyypillinen ongelma. Jos maadoitus on huonossa kunnossa, niin ehkä se vois aiheuttaa myös noiden happitunnistimien reistailua. Maadoitusongelmat usein oireilee jännittävillä tavoilla.
