Ошибка P0341 Лачетти 1.4/1.6

Ошибка p0341 – ошибка p0341 – ошибка датчика положения распредвала. сигнализирует о том, что датчик положения распредвала выдает неверный сигнал.

Causes

A code P0341 may mean that one or more of the following has happened:

• Cam sensor wiring routed too close to spark plug wiring (causing interference)
• Poor wiring connection at cam sensor
• Poor wiring connection at PCM
• Bad cam sensor
• Damaged reluctor wheel

Camshaft Position Sensor Circuit Range/Performance

Obdii коды для автомобилей. расшифровка значения кода диагностики p0341. причины появления ошибки p0341

Possible solutions

NOTE: In some cases this engine code is generated on vehicles that do not actually have a camshaft position sensor. In those cases it basically means the engine is misfiring badly due to faulty spark plugs, spark plug wires, and often coils.

Often relacing the sensor fixes this code, but not necessarily. Therefore it’s
important to check the following:

• Check that the wiring isn’t routed too close to any secondary ignition components
  (coil, spark plug wires, etc.)
• Visually inspect the wiring at the sensor for any burn marks, discoloration
  indicative of melting or chafing
• Visually inspect the cam sensor for damage
• Visually inspect the reluctor wheel through the cam sensor port (if possible)
  for any missing teeth or any damage
• If reluctor isn’t visible from outside the engine, visual test can only
  be done by removing cam shaft or intake manifold (depending on engine design)
• If all checks out okay, then replace the sensor.

  Long story short the cam sensor wires were pinched and shorted by the power steering pump on a 3.4L. The car would not start and there were no trouble codes. Finally I notice no cam signal on the scanner so I started to dig. I found the cam sensor wires to be shorted out. I repaired the wires. Still…

Symptoms

The car will likely run with this code set, as it is often intermittent and
also because the PCM can often operate the vehicle in “limp-in/limp-home”
mode even with a cam sensor signal problem. There may be no noticeable symptoms
other than:

• Poor fuel economy (if engine runs)
• Possible no start condition

What does that mean?

This diagnostic trouble code (DTC) is a generic powertrain code, which means that it applies to OBD-II equipped vehicles. Although generic, the specific repair steps may vary depending on make/model.

This P0341 code basically means that the powertrain control module (PCM) detected
a problem with the camshaft signal.

The camshaft position sensor (CPS) sends
a specific signal to the PCM for Top Dead Center on the compression stroke as
well as signals indicating the position of the cam sensor. This is accomplished
through a reluctor wheel attached to the camshaft that passes by the cam sensor.

Датчик положения распределительного вала, выход сигнала из допустимого диапазона

Описание схемы

Датчик положения распределительного вала (СМР) используется для определения положения распределительного вала, а также для взаимосвязи с положением коленчатого вала, для того, чтобы контроллер ЭСУД мог определить, в какой цилиндр форсунке подавать топливо.

Условия появления кода DTC

Условия установки кода неисправности

• Нет передачи сигнала датчика СМР между зубьями 25 и 33 и изменения полярности.

Действия, выполняемые при установке кода неисправности

• Контрольная лампа индикации неисправности загорается.
• Контроллер записывает рабочие условия в момент определения неисправности. Эта информация сохраняется в буфере записей состояния и протоколах неисправностей.
• Сохраняется архив диагностических кодов неисправности.

Условия очистки кода неисправности/индикации неисправности

• Лампа индикации неисправности выключается по окончании трех циклов проверки подряд, при которых диагностика выполняется без сбоя.
• Архивный диагностический код неисправности убирается после 40 циклов нагрева без сбоя.
• Диагностический код неисправности может быть очищен сканирующим прибором.

Диагностическая информация

Перед использованием диагностической таблицы проверить и устранить любой необычный шум двигателя.

Любая цепь, подозреваемая на создание шума двигателя, должна быть тщательно проверена на следующие обстоятельства:

• Снятые клеммы
• Соединение клемм
• Неисправность замков
• Деформированность
• Повреждения клемм
• Слабое соединение клемм с проводами
• Физическое повреждение жгутов проводов
