For checking codes, any off the shelf obd2 reader will do. If you want to have fun, ELM327 based OBD2 readers are all the rage right now. You can pick up a bluetooth version for ~$40 on amazon or ebay. Several iOS and android apps (like Torque) exist that can read a signal from these adapters and do full on data-logging. This will let you read/clear ...

Pending code? The user manual for your device says it should say "PD" for pending codes, so maybe not. "P0130 P" isn't a valid DTC for your vehicle so pending code is really all that makes sense. More specific to your model P0130 is front oxygen sensor circuit range/performance problem (Lean) Possible causes: Open wire to O2 Sensor Short to ground in O2 ...

If you are simply buying it to try to fix your car, and not as a tool to have, car part stores sometimes read the codes for you. The readers will usually have a description, but if not OBD-II became a government standard in 1996. The codes are basically the same accross the board, and any additional codes are manufacturer specific. To translate them, you can ...

ELM documentation indicates that this is not a query-only problem. I see on page 31 of that document that the issue was that of the rate at which J1850 requests arrive at the OBD system (this is a consequence of the April 2002 update of the J1979 standard). Specifically, they warn you against querying at rates higher than 100 milliseconds (also known as 10 ...

The diagnostic trouble code is not to be looked at as a root cause of the system failure. (example. Replacing a blown fuse is NOT a solution) In all cases there are multiple components that can cause the same code to trigger. For instance, a possible vacuum leak, or EGR problems, and even a PCV issue, could all show o2 sensor readings with tendencies towards ...

This should not cause you an issue, but this sounds more like a problem with the O2 sensors than with the intake gaskets. When was the last time you had them changed? If you are over 100k miles without new ones, I'd highly suggest this first. One way to check your theory for the intake gasket is by using a spray bottle with water (on jet, not spray). With ...

As Tim suggests, clearing the code doesn't solve the problem if it's not a random positive. The engine temperature gauge is fine Based on the information that you've provided so far (and using Tim's link as a reference), it seems likely that you have either a bad engine coolant temperature sensor. The implication from your PS is that the car is, in ...

I can't speak to the Torque app, but in my experience the US Gov ratings are typically quite a bit lower than what you can expect to get in actual normal driving (Gov ratings seem to be based around someone that does 15mph+ over the speed limit all the time, launches from every stop light, does full-throttle passing, and doesn't see red lights until they ...

Look at the ALDL connector if you have this on it's OBD II If you have something differant like the one below, it' not OBD II

Be cautious, OBD-II is not as standardized as most people think... Ford & GM both went their own ways with early OBD-II cars and industry standard "ISO only" readers won't work on them. You need tri-mode readers that also support VPW (? going from memory, I believe that's Ford's OBD-II interface) and whatever GM used. Side note, the Toyota Supra ...

This can be reproduced by turning the ignition on and off 3 times (somewhat quickly). ON, OFF, ON, OFF, ON. On the last ON switch, the speedometer should cycle through any error codes. I also found a site that documents this. Different vehicles seem to have different variables: http://www.allpar.com/fix/codes.html According to the site, this should be ...

Off the top of my head, the easiest way to get there would be using some sort of hobbyist microcontroller board, such as an Arduino. You'll need to add encoders since most of the data you'll be receiving will be analog. Since the CPU for your board will include timing by default, you can calculate time-based measurements (RPM, MPH, etc) from that. ...

Well, It's not necessarily dealing with the ELM327, but this looks like a FANTASTIC solution. Griffin CarTrip No longer getting developed. Apple is currently not allowing developers to use Bluetooth for this purpose. The only real connection is via Wifi. My initial "assumption" was that if you're connected via Wifi, then your 3G data is disabled and ...

Usually the OBD CAN bus is 'bridged' onto the other CAN buses of the vehicle, in order to facilitate diagnostics of ECUs on the other buses. However, the bridge may only pass diagnostic messages onwards :( It's different on every platform. In terms of the protocol - its a classic reverse engineering problem. You need to capture a few traces of the CAN ...

I found a site called actron.com that describes OBDII codes. Autozone explains what the camshaft position sensor is. Camshaft Position Sensor Actuator Operation The Camshaft Position (CMP) actuator is attached to each camshaft and is hydraulically operated in order to change the angle of the camshaft relative to Crankshaft Position ...

The 'Interpreting Trouble Codes' section (page 26) of the ELM327 Data Sheet has an example of how to fetch DTCs. You first make a mode 01 PID 01 request to determine the number of DTCs (which you'll need to decode the response in the next request). Then you make a mode 03 (no PID) request to get the actual codes. I'll try to paraphrase the example for ...

The answer would be yes if the vehicle was produced after 2008, otherwise no. in the following article it states it is required as one of the signalling protocols in OBD2 Post 2008. http://en.wikipedia.org/wiki/On-board_diagnostics#OBD-II_signal_protocols So presently vehicles that are currently being produced do have a CAN channel included in the OBD2 ...

I am not sure of your exact solution, but Brian Blum of Texas Instruments says the amperage draw depends on what state the device is in, of which there are seven states. According to the document in the link, it draws as follows: State 1 (wake-up) - 6.1mA State 2 (pre-processing) - 8.1 mA State 3 (pre-RX) - 12.3 mA State 4 (RX) - 22.3 mA State 5 (Rx-to-Tx) ...

Sounds like a lot of work for little gain. Consider doing slightly more work for much greater gains with something along the lines of an AEM EMS: http://www.aemelectronics.com/engine-management-systems-9/plug-play-engine-management-systems-ems-10/ Not the only game in town, but it is probably the most popular. Probably 90% of the standalone EMS ...

Apparently, code 1684 indicates a loss of power to the powertrain control module. One of the risks seems to be corrosion on the battery terminals or cables. As the easiest way to clear this code is to disconnect the battery (resetting the code and the check engine light at the same time), that would be a good time to check the battery posts for ...

To get smogged in California, you generally need to go to an "inspection-only" shop, that is, one that will only test your car but not fix it if it fails. (If it fails, you go to a regular mechanic and fix it, then come back for a free retest.) I believe the system was put in place to counter fraud; I don't really know how well that's working out. In any ...

Interestingly, you can read the code without a scanner. The airbag light or ABS light (and even the check engine light) will all blink the codes when the OBD-II connector is properly bridged. For example if it blinks 5 time slow and 1 time fast you have a 51 code. All you'll need is a paper clip. This video below will demonstrate how to do it. I just did ...

Readers for air bags, ABS, etc can be quite expensive. You can try searching online for PC apps and cables that might do it. I'm hoping somebody has come up with one by now. Last time I was looking for an ABS code reader for an OBD-II car it was ugly. The device was called a "MUTT-II" and cost $5,000. Even worse, it required a vehicle specific ROM pak, ...

Since the vehicle is a 96, the mechanic might have meant that you need 2 or 2 more OBDII monitor readiness checks. Some emissions systems are checked continuously by the powertrain controller, while others are only checked periodically when certain driving conditions are met (FAQ). Has your battery been disconnected? That could have reset the monitoring ...

Is it the one pictured at the Elm327 Bluetooth website? If so then the passcode should be 1234 although technically they say that the passcode is " 1234 " It's been a while since I paired a bluetooth device but I think you only get 4 digits to work with, not 6, and I think only numerics are allowed so no spaces either, which brings us back to ...

I'm leaning towards a bad thermostat. They gunk up and fail over time (usually on the "too cold" side). My experience with factory coolant temp gauges is that they're pretty much useless. My experiences show that the coolant temp can be a good 20 degrees (F) off of normal and the factory gauge will still sit in almost exactly the same spot as if the ...

If you're not sure why you would need one then no, it would not be a good purchase. You would be much better off telling us what's happening with your car: we might be able to be of assistance given some information on specific symptoms. The on-board diagnostic port will look something like this: It serves as an interface port that the engine computer ...

If you're looking for the OBD2 pin-out on the vehicles end (female) then it the interface type and pin population will vary from vehicle make to vehicle make. In order to tell you'll have to start by locating the OBD-II Connector. I'm going to assume since you're asking about this you know where to find this connector The connector has metallic contacts ...
