Are you concerned about the emissions coming from your car? If you are and you want to know more about how to address this issue, read on for information on emissions and car repairs.
'Systems Operation' Knowledge and Proper Equipment Saves Diagnostic Time and Speeds Repair Process It may not be a Mother-in-Law light, but the effect can be about the same. Just when you don't want to see it, there it is! The Malfunction Indicator Light (MIL) has been around for more than 25 years, but since OBD II standards made the electronic monitoring of emissions mandatory, that light seems to have been given new life.
When Onboard Diagnostics II was first conceived as a means of monitoring vehicle emissions, it was obvious there would be a lot of information to keep track of. The Society of Automotive Engineers (SAE) developed guidelines for managing all of this information and came up with a list of "diagnostic modes" that scan tools would have to provide.
OBD II can diagnose engine misfires. On most applications, the OBD II system looks for subtle variations in the speed of the crankshaft to detect misfires. The powertrain control module (PCM) monitors the input from the crankshaft position sensor and checks the rpm reading between cylinder firings. For more details of OBD II engine diagnostics, keep on reading will be a good choice.
You must know that most O2 sensors are the switching type that generate a rich or lean voltage signal depending on how much unburned oxygen is in the exhaust - unless it's a Nissan or Toyota titania O2 sensor that changes resistance to indicate a rich or lean condition in the exhaust.
Is there a diesel in your service bay? Maybe not now, but there definitely will be in your future. You're going to see trucks as well as SUVs and passenger cars. Read on for more detailed information in the following article.
The MIL comes on with one or more of these evaporative DTCs stored: P0451 (FTP sensor circuit range/performance problem); P0452 (FTP sensor circuit low voltage); P0453 (FTP sensor circuit high voltage); P1454 (FTP sensor circuit range/performance problem). The FTP (fuel tank pressure) sensor has an internal malfunction. Replace the fuel tank pressure sensor. Read on for more.
The vehicle's fuel tank may need to be replaced. Use the appropriate Service Procedure provided in this bulletin to diagnose and repair these incidents, if they should occur.
Under certain conditions, customers with various 2002 Camry and Solara, and 2001-’02 Highlander and RAV4 vehicles may experience an MIL on condition with DTC P1349, indicating a variable valve timing (VVTi) malfunction. In some cases, the cause of this DTC may be the VVTi actuator. Use the procedures in this bulletin to verify the operation of the actuator.
