Emissions Codes - Decoding the OBDII Diagnostic Code

When the "check engine" or "service engine soon" light comes on, it doesn't tell you what or where the trouble is, only that there's trouble. You've hooked up your scanner to the vehicle computer and retrieved the OBDII diagnostic code. What does it mean?

The "OBD" of OBDII - sometimes written OBD-II or just plain OBD2 - stands for On-Board Diagnostics. The "II" is the next generation of emissions standards and codes for all vehicles sold in the U.S. from 1996 to the present, domestic and imports.

The OBD2 system is primarily for emissions control. Its basic components are the catalytic converter and strategically-placed oxygen sensors. These as well as everything in the vehicle having to do with engine performance and emissions control are continuously monitored by the vehicle's on-board computer system.

The "check engine" or "service engine soon" light is the signal that there is a problem with the vehicle's emissions. The computer has assigned a trouble code to the problem and turned on the trouble light - technically called the Malfunction Indicator Lamp (MIL).

When you retrieve the information from the computer via an OBDII diagnostic scanner, it doesn't tell you the problem directly, such as "timing too slow" or "misfire in cylinder number four". What you get is a five-digit alpha-numeric code such as "P0304".

The first digit is a letter corresponding to the main system causing the trouble code:

B = Body
C = Chassis
P = Powertrain
U = Network

The next four digits are all numbers. There is never a letter "O" in the OBDII diagnostic code. It is the numeric digit zero ("0").

The second digit corresponds to the type of code, whether it is the generic standard applying to all OBDII-compliant vehicles, or a manufacturer-specific code.

0 = Generic codes
1 = Manufacturer-specific codes
2 = Includes both generic and manufacturer-specific codes
3 = Includes both generic and manufacturer-specific codes

The third number corresponds to the sub-system where the problem lies.

1 = Fuel and Air Metering
2 = Fuel and Air Metering (injector circuit malfunction only)
3 = Ignition System or Misfire
4 = Auxiliary Emission Control System
5 = Vehicle Speed Control and Idle Control System
6 = Computer Output Circuits
7 = Transmission
8 = Transmission

So our example trouble code P0304 indicates a problem in the powertrain. It is a generic code for trouble with the ignition system or a misfire.

The fourth and fifth numbers of the code correspond to the section of the system causing the trouble. The list of all these sections is long, but you can see how the final "04" in our example points to a misfire in cylinder number four.

Most OBDII diagnostic scanners will come with a code library of specific code meanings. A list may also be found on-line by Googling "obd2 codes list".

You will sometimes find a reference to "Bank 1" or "Bank 2" in the code explanation. These banks are generally meant for "V-type" engines. Bank 1 refers to the side of the engine with the number 1 cylinder (odd-numbered cylinders). Bank 2 refers to the side of the engine with the number 2 cylinder (even-numbered cylinders).

A misfire is a "one-trip" or "type A" problem that by itself will not turn on the MIL unless it is severe enough to damage the catalytic converter. A severe misfire will not only turn on the MIL but will signal it to flash at one-second intervals.

Other problems are usually "two-trip" or "type B" problems. When the computer first detects a two-trip problem, it stores the trouble code as "pending". If on the next driving trip the problem has passed, the pending code is erased. But if the problem is still there on consecutive trips, the computer will turn on the MIL, alerting the driver to a problem.

The MIL can be persistent. Once on, it will stay on until the problem is resolved for three driving trips. However, though the light may go out, the codes remain in the computer memory for 40-80 trips depending on the problem.

Trouble codes remaining in the computer memory will cause a failed emissions inspection whether the "check engine" light is on or not.

Of course, your diagnostic scanner can turn off the MIL and erase the codes from the computer's memory. This will not do much good, however, if the problem recurs after two driving trips and regenerates the trouble codes. The information from the scanner should be used to locate and fix the problem, not just turn off the MIL and erase the codes.

Frequency Response Analysis with OMICRON FRAnalyzer
Frequency response analysis, or FRA, is a powerful tool to ensure the integrity of a power transformer. It is typically used to detect if the core and winding assembly has electrically or geometrically changed due to a short-circuit fault or a relocation. Furthermore it is used for routine diagnostic measurement, and for further diagnosis, if routine testing or monitoring identify irregularities. Get more information: www.omicron.at

HP Printer Troubleshooting - Why It's Easier With the HP Diagnostic Tool

Users can infer a device driver problem or hardware malfunction whenever the HP wireless printer is not working. A quick update and reinstall of the software driver will resolve the driver issue. But when hardware trouble arises, troubleshooting must be precise in order to identify and replace the faulty components.

HP Printer Troubleshooting - Why It's Easier With the HP Diagnostic Tool

The more recent HP printer models come with built-in troubleshooting capabilities that can accurately pinpoint any lapses in printer operation. The integrated package of utilities is called the HP Diagnostic Tool. This is an important feature that allows users to solve common printer issues. The software actually works like a commissioned, expert printer technician that is on call 24 hours a day to provide all the answers to typical user queries.

The diagnostic printer feature covers most issues that users encounter in the course of printing. Possible sources of problems can be diagnosed through the following utilities:

HP Print and Scan Doctor. The utility resolves various printing issues such as corrupt or missing drivers, firewall and connectivity issues, scan error messages and whenever print Jobs get stuck in the print queue. HP Windows 7 Printer Install Wizard. The tool automatically uploads the best driver compatible with the printer. This is particularly useful when the user fails to locate the Windows 7 driver or not sure which driver to select. HP Scan Diagnostic Utility. The utility troubleshoots scanning issues easily, which includes an unresponsive scan button on the control panel, a pausing scan preview window and the display of a scan error message in the course of scanning via HP's software. HP Hardware Diagnostic Utility. The tool serves as the main resource when resolving various hardware related problems. This includes paper jams, paper mismatch, blinking lights and print quality troubles among others.

The degree of importance of the HP diagnostic tool to the user is hard to quantify. When print troubles strike, the HP diagnostic tool pinpoints the root cause of the problem. There is no guessing game and maintenance can immediately be conducted. The HP printer can therefore resume operation once again with minimum downtime.

All HP printers are designed for trouble-free printing. However, operation glitches can occur because each unit comes with so many moving parts. Printers will of course succumb to regular wear and tear as the unit ages. And it may even refuse to work. Connectivity issues could also trigger software conflicts and cause the printer to shut down. Whatever the issues at hand may be, these must be resolved immediately to reduce printer downtime.
