I am currently dealing with 2010 passat CC and has misfire with rough running in all cylinders. . The PCM (powertrain control module) sets code P0342 when it detects that the camshaft position sensor circuit on engine bank 1 is sending a reading that’s erratic or otherwise outside the manufacturer’s settings. Thanks for any input. Tech Notes: Sometimes and in some models, low battery voltage or a weak starter can trigger a Camshaft Position Sensor code. Vehicle does not drive like it used to. If the pressure is too low, you may need to replace the fuel pump or the fuel injectors. Diagnostic trouble code (DTC) P0345 stands for “Camshaft Position Sensor “A” Circuit (Bank 2). ; Air– It needs to be metered by your Focus’s mass air flow sensor or MAP sensor, so the powertrain control module (PCM) knows exactly how much air to let into the combustion chamber. Along with P0300, you’ll probably see another OBD-II code, ranging from P0301 to P0308. A DTC is not always stored. The (1/1) Exhaust Camshaft Position Sensor (2) is mounted to the front face of the cylinder head on the same side as the exhaust camshaft.

If one of these sensors’ values is out of the specified range, the check engine light will show up. -- Ford power balance test via scan tool has shown misfires on every cylinder. EGR or EGR valve. You’ll likely see P0171 and P0300 when there’s a vacuum leak. 0 with misfire all cylinders random/multiple but no timing codes or no crank shaft or cam shaft - Answered by a verified Audi Mechanic. Ignition System Problems. The timing belt/chain is out of time. Unplug the sensor’s electrical connector from the engine wiring harness. 2. Replace the camshaft and camshaft bracket if out of specification. This helps to sync your injectors and provides the coil firing sequence to the ECU. Parts alone will run about $25 to $100. The cam sensor (CMP) on the bank being controlled closes the feedback loop so the ECM/PCM can determine how much camshaft advance is needed (depending on engine load, speed,. P0340 Camshaft Position Sensor “A” Circuit;. Code P0300 is. . 0 split port engine. Different manufacturers have slightly different criteria for when this code is set, but a P0011 code points to an Advanced Camshaft Timing condition that won’t respond to PCM commands. Issue Severity: SEVERE – Stop driving immediately. A lean misfire would mean injector #1 isn't firing, or only partially firing.
