P1116 definition A P1116 trouble code is related to a vehicle’s engine coolant sensor that sends a temperature signal to the engine computer so it can relay a signal to the...
Just because the computer does not have any codes does not mean one of the sensors is not reading correctly. If you are using an oil bath type air filter, it may have contaminated the mass air flow sensor with...
Check fuse number 11 in fuse box to see if it is blown. Check all fuses in engine and interior fuse boxes for any blown ones. You may need to try disconnecting the engine control module and reconnecting it...
OBD-II came out in late 1995 in some vehicles, and all vehicles from 1996 onwards. You may need to try an OBD-1 scan tool or try to obtain the codes another way. It is also possible that you have some...
Misfires can be caused by several things. I would first check for vacuum leaks, then I would pull the plugs to see if they need replacing. It is possible that have a fuel system concern, but I would lean more...
A logical place to start is with a Check Engine Light inspection to see what codes might be set. Usually with something of this nature, codes will be present, and there will be a flow chart that should be used...
This sounds like a low fuel pressure problem, or an air filter and mass airflow (MAF) sensor problem. Check the fuel pressure and replace the fuel filter first to see if it helps. Next, have the system computer scanned...
When it comes to across-the-board codes being set such as this, it is usually a result of something "upstream" creating the condition to set all these codes. For instance, it is rare for both O2 sensors to fail at exactly...
Hello. The MAP sensor reading on a scanner should read about 1.0 to 1.5 volts at idle and 4.5 to 4.8 volts at wide open throttle. The MAP should read 4.8 volts or more when you have the key on...
Hey there. If you have the OBD-2 connector under the dash directly under the steering column, then the ELM327 will work to scan the vehicle after you download the app. I can tell you that this adapter is very cheaply...
All vehicles that are newer than 1996 and sold in the United States are required to have an OBD-2 system. The scanner plug may have been removed for some reason by the previous owner or mechanic. If this is the...
When this situation occurs, the first thing I look for is checking the fuses or electrical relays to the ECU. In general, the most common cause of being unable to connect to the scanner or to the ECU is caused...
Hello. Since this could be a variety of potential issues, I would recommend hooking the car up to an OBD scanner to download any trouble codes that may have registered as a result of the light coming on. I would...
The brake pedal position does not have a specific wire to the OBD2 connector that can be monitored. You could however monitor the data stream and get the brake on or off PID in the data monitoring. The PID will...
Hello there. The knock sensor code can have various causes on your 2004 Chevrolet Silverado. The knock sensor circuit low, bank 1 code is telling us that the knock sensor in bank 1 that it has low circuit voltage. This...
These aftermarket type scanners may not access every vehicle out there. When you get a cannot communicate issue this is most likely the OBD adapter and the vehicle may be incompatible or the vehicle has problems. You would need to...
When the Check Engine Light comes on without any specific warning, this can indicate a variety of possible issues. Unfortunately, without more specific symptoms, this can be tough to diagnose without the use of a scanning tool and the skill...
Hello. If your monitors are showing not ready, then that is because the computer was recently reset or the battery may have been replaced. If either of these occurred, then there is a specific amount of driving that needs to...
Your vehicle's OBD connector is located on the driver's side of the vehicle underneath the dash to the right of the steering column just above the gas pedal.
There are two (at least) quite distinct issues in regard to your general request: The first is, once a check engine light illuminates, what are the most "frequent" codes that are stored and thence downloaded, that is what does THAT...
