P0335 - GM Type Powertrain - Ignition System or Misfire - ISO/SAE Controlled
Description

CKP Sensor Performance Conditions
Cause

Engine speed under 300 rpm, then the PCM detected that 8 consecutive CKP sensor signals were missing for 8 Cyl No 1 events, or with the engine running, then the PCM detected 8 consecutive CKP signals were missing for 32 Cyl No 1 events

What does that mean?

The crankshaft position sensor (CKP) measures crankshaft location and relays this information to the PCM (Powertrain Control Module). Depending on the vehicle, the PCM uses this crankshaft position information to time the spark properly or on some systems it is only for misfire detection and does not control spark timing. The CKP sensor is stationary and works in harmony with a reluctor ring (or toothed ring) that is attached to the crankshaft. As this reluctor ring passes in front of the CKP sensor, the magnetic field created by the CKP sensor is interrupted and this creates a square wave voltage signal that the PCM interprets as crankshaft position. If the PCM detects that there are no crankshaft pulses or if it sees a problem with the pulses on the output circuit, P0335 will set.

Symptoms

NOTE: If the crank sensor is used only for misfire detection and NOT spark timing (this varies with the vehicle), the vehicle should start and run with MIL (Malfunction indicator lamp) illumination. Also, some vehicles require several key cycles to illuminate the MIL. If this is the case, there may be no MIL illumination until the problem often enough over time. If the crank sensor is used for BOTH misfire detection and spark timing, the vehicle may or may not start. Symptoms may include:

Vehicle may not start (see above)
Vehicle may run rough or misfire
MIL illumination

Causes

A P0335 "check engine light" code could be caused by:

Damaged CKP sensor connector
Damaged reluctor ring (missing teeth or not turning due to sheared-off keyway)
Sensor output open
Sensor output shorted to ground
Sensor output shorted to voltage
Failed crank sensor
Broken timing belt
Failed PCM

Possible Solutions

Using a scan tool, check if, when engine is running or cranking, that there is an RPM signal.
If there is no RPM reading, then visually inspect the crank sensor and connector for any damage and repair as necessary. If there is no visible damage, and you have access to a scope, you could check the CKP 5 Volt square wave pattern. If you do not, then, obtain a resistance reading of your crank sensor from a repair manual. (There are so many different types of crank sensors that there's no way to put here which resistance reading is correct). Then check the resistance of the CKP sensor by disconnecting the sensor and measuring resistance of the sensor. (It is best to check resistance readings from the PCM connector. This rules out any wiring problems from the start. But it does require some mechanical skill and shouldn't be performed if you\'re not familiar with automobile electrical systems). Is the sensor within resistance specs?
If not, replace the CKP sensor. If so, recheck resistance reading from the PCM connector. Is the reading still okay?
If not, repair open or short in the wiring to the crank sensor and re-check. If the reading is okay, the problem is intermittent or the PCM may be at fault. Try reconnecting and checking for RPM signal again. If there is now an RPM signal, wiggle test the wiring harness to try and induce the fault.

This code is basically identical to P0385. This code P0335 refers to Crankshaft Posistion Sensor "A", whereas P0385 refers to Crankshaft Position Sensor "B". Other crank sensor codes include P0016, P0017, P0018, P0019, P0335, P0336, P0337, P0338, P0339, P0385, P0386, P0387, P0388, and P0389.



P0380 - GM Type Powertrain - Ignition System or Misfire - ISO/SAE Controlled
Description

Glow Plug Performance Conditions
Cause

Glow Plugs commanded on, then the PCM detected the voltage at the plugs was less than 4.0v, or with Glow Plugs commanded off, then the PCM detected that the voltage at the plugs was more than 4 Ov, or with the Glow Plugs commanded on, the PCM detected more than a 2v difference between the system and plug voltage

Nu am probleme cu functionarea motorului

Senzor volanta = senzor vibrochen = senzor arbore cotit = crankshaft sensor. Senzorul este unul si acelasi, masoara turatia motorului si este amplasat pe blocul motor in zona demarorului. Accesul la el se face pe sub motor, dupa ce se da jos tot scutul motorului.

Am rezolvat. Am schimbat senzorul si, deocamdata, motorul functioneaza normal.

L-am luat de pe un site (autokarma) cu 197 lei + taxe=222. Este Facet. Acum au Fae la 167 de lei.

salut am un opel astra g din 2001 motor 1,7 dti motor isuzu.am plecat ieri dimineata din parcare si s-a aprins martorul cu motorasul pe el am mers vre-o 100 de km si tot nu se stinge.am facut testul cu pedalele si am obtinut urmatoarele cifre: 1 2 11 1 5.imi poate da cineva un raspuns multumesc

P0300 nu exista la 1.7dti. Ai citit gresit.

Foloseste cu incredere campul "cauta" din dreapta-sus. Uite ce am gasit eu: https://www.clubopel.com/rez...p;q=pseudo-agrafa

Presupunand ca senzorul luat de la dezmembrari era bun, asta este inca o dovada ca daca stii sa citesti un cod de eroare nu esti si neaparat un expert in diagnoza auto. Pe baza erorii aflate se urmeaza o procedura specifica de izolare a defectului, nu se inlocuieste una-doua senzorul descoperit in descrierea erorii.
