Question about 2006 Mazda 6

3 Answers

2005 Chrysler Pacifica awd, OBD-II reads DTC P0305, Chrysler wanted to charge $800 to lookin further into the engine, I had a radiator and air filter system replaced due to an accident, now the ac wont work and still waiting on a vacuum hose from the dealer. Said spark plug and coils were fine. Could the missing hose cause the car to stall when reaching 60mph. They said all cylinders were running 175psi but the cylinder 5 only reading 100. COuld the hose contribute to this

A low reading at #5 is of concern...I'd want to know why before going further. If the missing vacuum hose in some way connects to that cylinder, it may have leaned out and burned a valve if the fitting was left open. I don't see a connection to stalling though. You have several issues going on here, all of which need to be resolved. A cylinder leakdown test can tell you if compression is going past the rings or valves. I'd go there first.

Most definitely could. a vaccum hose can contribute to alot of problems in the long run. your engine needs a certain amount of back pressure to run and the faster you go the higher the pressure goes. trying covering the the fitting where this connects to the engine and hit high speeds,SAFELY, and see if the car stalls. try your local patrs dealer for the hose and dont give the dealer anymore money.

Error code PO171 Mechanic said i need to replace bank One Sensor 2. 89467-42010, 89465-42090, 89467-42020, 89465-42100. Which one do I have to replace?


following answer courtesy of OBD-CODES.com OBD Codes Your OBD-II Trouble Codes Repair Site Home Trouble Codes FAQs Forums Store P0171 OBD-II Trouble Code Technical Description System Too Lean (Bank 1) What does that mean? Basically this means that an oxygen sensor in bank 1 has detected a lean condition (too much oxygen in the exhaust). On V6/V8/V10 engines, Bank 1 is the side of the engine that has cylinder #1. The P0171 is one of the more common trouble codes. This code is triggered by the first downstream (front) O2 sensor. The sensor provides a reading of the air:fuel ratio leaving the engine's cylinders, and the vehicles powertrain/engine control module (PCM/ECM) uses that reading and adjusts to keep the engine running at that optimum ratio of 14.7:1. If something is not right and the PCM cannot maintain the 14.7:1 ratio, but rather there is too much air, it triggers this code. You'll want to also read our article on short and long term fuel trims to help understand the operation of the engine. Note: This DTC is very similar to P0174, and in fact your vehicle may show both codes at the same time. This diagnostic trouble code (DTC) is a generic OBD-II powertrain code. It is considered generic because it applies to all makes and models of vehicles (1996-newer), although specific repair steps may vary depending on the model. Symptoms You will more than likely not notice any drivability problems, although there may be symptoms such as: a lack of power detonation (spark knock) rough idle hesitation/surge on acceleration. Causes A code P0171 may mean that one or more of the following has happened: The MAF (Mass Air Flow) Sensor is dirty or faulty Note: The use of "oiled" air filters may cause the MAF to become dirty if the filter is over-oiled. There is also an issue with some vehicles where the MAF sensors leak the silicone potting material used to protect the circuitry. There could be a vacuum leak downstream of the MAF sensor Possible cracked vacuum or PCV line/connection Faulty or stuck open PCV valve Failed or faulty oxygen sensor (bank 1, sensor 1) Sticking/plugged or failed fuel injector Low fuel pressure (possible plugged/dirty fuel filter!) Exhaust leak between engine and first oxygen sensor Possible Solutions A lot of times, cleaning the MAF sensor and finding/fixing vacuum leaks fix the problem. If you're on a tight budget, start there, but that may not be the fix for certain. So, possible solutions include: Clean the MAF sensor. Consult your service manual for it's location if you need help. I find it's best to take it off and spray it with electronics cleaner or brake cleaner. Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling Inspect all vacuum and PCV hoses, replace/repair as required Inspect all hoses and connections in the air intake system Inspect and/or test the intake manifold gaskets for leakage Check for a dirty fuel filter and proper fuel pressure Ideally you'll want to monitor short and long term fuel trims using an advanced scan tool If you have access, you may want to run a smoke test

What is code , po299' on mitsubish shogun 2008


the following answer is courtsey of OBD-CODES.com OBD Codes Your OBD-II Trouble Codes Repair Site Home Trouble Codes FAQs Forums Store P0299 Turbo / Supercharger Underboost OBD-II Trouble Code Technical Description Turbocharger/Supercharger "A" Underboost Condition What does that mean? The P0299 DTC code refers to a condition where the PCM/ECM (powertrain/engine control module) has detected that the bank "A" or single turbocharger or supercharger is not providing a normal amount of boost. That could be due to a variety of reasons, which we detail below. On a normally operating turbocharged or supercharged engine the air going into the engine is pressurized and that's part of what makes so much power for an engine of it's size. If this code is set, you will likely notice reduced power output. In the case of Ford vehicles, this may apply: "The PCM checks for a minimum throttle intake pressure (TIP) PID reading during engine operation, which indicates an underboost condition. This DTC sets when the PCM detects that the actual throttle intake pressure is less than the desired throttle intake pressure by 4 psi or more for 5 seconds." Symptoms Symptoms of a P0299 DTC may include: MIL (Malfunction indicator lamp) illumination Reduced power output from engine, possibly in a limp mode Unusual sounds from the engine/turbo There would likely be no other symptoms. Potential Causes Potential causes of a P0299 turbo underboost code include: Intake (induction) air restriction or leak Failed or damaged turbocharger (sticking, binding, etc.) Faulty boost/charge pressure sensor Faulty wastegate bypass regulator valve (VW) Low fuel pressure condition (Isuzu) Sticking turbo nozzle control solenoid (Isuzu) Faulty injector control pressure (ICP) sensor (Ford) Low oil pressure (Ford) EGR system fault (Ford) Variable geometry turbocharger (VGT) actuator (Ford) VGT vanes sticking (Ford) Possible Solutions First off, you'll want to repair any other DTC codes if present prior to diagnosing this code. Start with a visual inspection. Inspect the intake air system for cracks, loose or disconnected hoses, restrictions, blockages, etc. Repair or replace as required. If the air induction system tests OK, then you'll want to focus your diagnosis efforts on the charge pressure control, diverter valve (blowoff valve), sensors, regulators, etc. Really at this point you'll want to refer to a vehicle specific detailed repair manual for specific troubleshooting steps. There are some known issues on certain makes and engines so also check out our car repair forums here and search using your keywords. For example, if you search around, you'll find that a common fix for a P0299 in VWs is to replace or repair the diverter valve or wastegate solenoid. On the GM Duramax diesel, this code may mean the turbo housing resonator has failed. If you have a Ford, you'll want to next check the wastegate regulating valve solenoid for correct operation

I have a 2005 Chrysler pacifica. Today it hesitated and stalled almost 2 miles from home . It would jump to 1000 rpm and stall the rest of the way home?


you should have OBD alarms coming in. It sounds like engine is not getting correct air/ fuel mixture due to failed component or failed sensor. Need OBD code to isolate or work in the correct area.

Dodge obd code p0305


The DTC (Data Trouble Code) P0305 is the generic OBD-II DTC for "Cylinder 5 Mis-fire Detected", and it means that the OBD-II control unit has detected a problem with the #5 cylinder.

The problem could be a faulty spark plug, or a spark plug wire for the #5 cylinder, or the coil for that cylinder could be faulty (2.7 liter), or the distributor or distributor cap could be faulty (3.0 liter), or the fuel injector for the #5 cylinder could be faulty.

Before you look for any electrical problems causing the mis-fire on the #5 cylinder, first do a compression check to be certain that the mis-fire is not caused by a mechanical problem.

Here are the firing order diagrams for the 2.7 and the 3.0 liter enginesto help assist you.
