    Hi Adil, I'm sorry you haven't traced the problem but what you need is a dealer or truck specialist that can get the codes sorted out. It may cost you to have the code read but save time and money in the long run by not putting costly parts on at random hoping to fix it. 5 mins with a code reader could lead to something broken or hanging off thats a quick fix?

Its probably trying to tell you there's something wrong with the engine? Some ECU controlled engines go to a soft power mode to limp along with. Search for a manual or contact a dealer. I presume you have done all the engine checks?

Driving my bmwz4 2005 auto suddenly no power. After stop then it starts again in about 5 minutes. Am desperate please help!!!!


Does the Check Engine or Service Engine Soon light come on? If so, there is an error code stored in your car's onboard computer. This code can be read and interpreted to provide a starting point for troubleshooting the problem. If no light, I would suspect bad gasoline (water or contaminants in fuel), loose wiring to the fuel pump, clogged fuel injectors or fuel filter, or an ignition electrical problem. Without additional information, it is very difficult to diagnose. If the Check Engine or Service Engine Soon light illuminated, take your car to a larger auto parts store and ask the counterperson to read the error code with their diagnostic scanner. They can interpret any code and advise what corrective action(s) may be required. Good luck.

Chrysler P0560 code


Generic OBD Error Code Details for P0560 System Voltage OBD II Code P0560 refers to
The battery supplies electricity to the ECM even when the ignition switch is OFF. This electricity allows the ECM to store data such as DTC history, freeze frame data, fuel trim values and other data. If the battery voltage falls below a minimum level, the ECM will conclude that there is a fault in the power supply circuit. The next time the engine starts, the ECM will turn on the MIL and a DTC will be set. SymptomsPossible sumptoms of OBD code P0560
- Engine Light ON (or Service Engine Soon Warning Light) - Slow engine start - Low battery power CausesPossible causes of OBD code P0560
- Loose or missing alternator drive belt - Faulty alternator - Battery defective - Open or short system voltage circuit The Error code is generally activated on detection of the following conditions: The P0560 code is detected when there is an open in ECM back-up power source circuit

My 2002 gmc sonoma (extended cab sls) will not start i have changed plugs and wires fuel pump and fuel filter i have done oil change and air filter change. the truck will fire if i give it a spray off...


My engine light in my 2002 GMC Sonoma has been on for the past four weeks. Yesterday I had an oil change done on my truck with a local mechanic. He turned the engine light off, but it came on soon after leaving his shop.
This morning I went to start my truck and there was NO power whatsoever. After repeatedly turning the key, I soon saw a slight movement on the battery display, but no lights would come on. It just seemed like it wasn't getting any power. I changed the battery two years ago, so it should be fine.
Eventually, the truck received full power and started, more less out of no where. It wouldn't hold an idle and would just die if i took my foot off the gas.
Hopefully someone has a solution for me.
Thanks.

How to clear code service engine soon 2002


you need to use an OBDII scan tool that will read any "error" codes and give you the system that will be causing the check engine light to come on. this tool will also allow you to erase the code after you have read it. write the code down as you may have to pinpoint exactly what part may have failed and needs replacing. something as simple as a loose gas cap will cause the check engine light to come on. it could be any of a dozen different emission or ignition sensors that may be bad depending on the error code. all 1996 and newer vehicles sold in the US will have the OBDII system and standard diagnostic/data link connector,which is usually under the driver side of the dash, to plug the scan tool into to read the DTC's(diagnostic trouble codes).

Get the codes that were saved when the "engine light" came on and post them here. (You can get them retrieved for free from Auto Zone).

I'm going to take real *wild* guess that somehow that rough spot you hit actually impacted the oxygen sensor and disconnected it or damaged it.
