Question about 2005 Mazda 3

Open Question

Engine persistently cuts out whilst driving

We have a quote to fix our failing Mazda 3. The error codes given on the quotation from the garage are U1900, B1261, U0100 and U0101 - so basically communications issues I understand. The proposed repair is a replacement of the "Speedometer". Comments and advice gratefully received?

SOURCE: 03 Mazda 6: Check engine light on, code po174

The oil pressure sensor does not have much to do with the P0174 code so the leak on the gasket is not the cause, usually it is the air mass sensor, or the intake sensor. if you have a leak of oil, this might as well mean that whoever changed the oil did not put the right specs of it and this caused the oil to get through. After some time you will experience that the rpms will reach only certain level and won't go higher. Change oil to the right specs and get the sensor cleaned if not to late or replaced (will be expensive). Gasket change wil be needed as well.

SOURCE: I had my 2004 Mazda

Codes that begin with the letter U are always communication fault codes between modules in a CAN system. They are basically to be ignored unless a problem is occuring. This is because all of the control modules in your car ( and there are a bunch of them ) are all communicating to each other and sending information between each other on one set of wires called a "twisted pair" Due to the high volume of infomation being sent and received there is the invevitable time when a message will be sent from one module to another and it is lost or not responded to in a timely manner (meaning in milliseconds) When this occurs then a U0100 or other comm fault code is stored.

Starting issues

The Engine and Automatic Transmission (not applicable to manual transmissions) in this vehicles drive train are fully electronically controlled by a computer called the PCM and TCM (Power Train Control Module, Transmission Control Module). When a problem like this or other drive-ability related problems occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump, engine coolant temperature sensor and MAF sensor for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPENDING YOUR HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM. Also always check fuel pressure for correct spec for your make and engine type.

Po300 code

If the problem isn't fixed the error code will keep returning. You'll need to get the ignition system checked from the spark plugs back over, (plug leads, ignition coil, etc). The injectors might need checking as well.
