The CEL can be triggered for a number of reasons, depending on what the manufacturer wanted. Only some of those reasons are emissions-related. Everything in the OBDII code list is, in some way, related to emissions. I'd guess that something happened which triggered the light, but the condition didn't persist. So, no codes when it was scanned. However, all ...

Check circuit F28 for open. (Pin 9 DLC to A16 PCM) EDIT: Check pin 3 (Immobilizer) to 14 DLC for continuity. If okay, may be inclined to replace immobilizer as first course of action. After replacement, consider researching Honda 'automatic key registration'. Unfortunately, I don't have the time to look into it. Recently, I replaced an immobilizer on a ...

Just a few days ago, I was successfully able to Integrate tk306a OBD with my car, it has all those functionalities to communicate with a custom cloud and an application. I can setup my own custom alerts, alarms, geofences, etc

My suggestions for next steps to take: Vacuum gauge testing at a warm idle, is it steady? A running compression test as well. Mechanical integrity should be verified before chasing any bad data theories. Freeze frame data, you mentioned the light comes on at a warm idle. Does your freeze frame agree? Correct me if Im wrong, but your vehicle will shut ...

Make cable to the device with an on/off switch in the +12v line - if it does not get power it won’t work - just remember to turn it off when you finish . You could also use an ignition controlled relay to do the same so it comes on with the engine but will be off when you stop.

I don't believe they can effectively clean that far down the line. Either take the car on the motorway for 10miles or so, keep the revs and speed up. Or you could remove the DPF which could possibly fail an MOT OR there's a thing called terraclean which is looks like it does something. It's a machine with fluids that connects to the engine but when you see ...

Finding someone who has VCDS would be your easiest method of finding out what is happening. That will be able to read the body computer. Look around locally for a VW car club. With VCDS you will read through the normal ODBII cable, and on a computer you will have the ability to read codes, status, etc. on the body computer. A well equipped shop may have ...

The voltage can and does vary... you need a multimeter as a minimum. With the engine at about 2000rpm you should see somewhere between 13.7 and 14.8 (can be up to 15.3) volts depending on the type of alternator. However, if the battery is low on charge you may be around the lower end of the voltage. If you want to test the current then you need to be ...

There are no OBD parameters that specify, or even remotely hint to a particular time to change spark plugs. The best gauge of spark plug health is to pull one ans "read" the color, deposits, and electrode and insulator condition. Another simple method is to replace conventional spark plugs every 35k miles, Platinum plugs perhaps every 50k-70k miles, and ...

I've frequently seen this fault logged by Volkswagens cars that have a poor condition battery, or a battery that has become discharged. The best probable explanation I can come up with is that the "false start" you described caused a drop or spike in voltage (or even removed voltage from the supply line, depending on what you did with the ignition key) ...

An "implausible signal" is one that doesn't make sense in the context of the system -- for example a signal voltage that is outside of the normal range of a sensor. This could be an early sign of a failing component but in your case it may also be due to the voltage drop that happens normally during a start. Many electronic components will behave in ...
