"service engine soon" light is on continuous, and lack of power
My "service engine soon" light is on continuously, and sometimes flashes during acceleration. There is a big lack of power on inclines, and when trying to accelerate to highway speed. The engine sounds quiet, but sometimes trembles slightly in idle. Van has 157,000 miles. Aside from the obvious, and taking it in to have a 'code' check, are there common solutions to this? Owner's manual says this problem is related to the emission control system, could it be a sensor?

Faulty Ignition Coil 1
Ignition Coil 1 harness is open or shorted
Ignition Coil 1 circuit poor electrical connection
Faulty Engine Control Module (ECM)
What does this mean? When is the code detected? Each ignition circuit is continuously monitored by the Engine Control Module (ECM). The test fails when the ECM does not receive a valid pulse signal from the ignition coil. Possible symptoms Engine Light ON (or Service Engine Soon Warning Light) Lack/Loss of Power Engine may be harder to start Engine hesitation Rough engine idle P0351 TOYOTA Description: The ignition system on the vehicle uses individual ignition coils for each cylinder. The Engine Control Module (ECM) controls each ignition coil operation. The ECM sends a ON/OFF signal to energize the ignition coil to create a spark at the spark plug when a spark is required at the cylinder.
Service engine flashing is your engine is misfiring its a sing that tell you if you continue driving like that you might damaged the cathalitic convertor on of the cylinder is not working get the car pass on a scanner to see wish cylinder is defective ll post a video that will explain what it is
When the check engine light flashes it means the the ECM is receiving conflicting or out of range information from one or more of the vehicles engine management sensors, and has gone into what is known as open loop (or limp) mode. This allows the vehicle to continue to run, although poorly perhaps, until the engine can be serviced. It is not recommended to run the engine this way for long, as damage can be the result. Have the ECM codes read and the engine services as soon as possible to clear up the issue.
spark plugs can cause misfires for sure. If you swap the number two cylinder plug with another cylinder then retest the code and the code stays on the same cylinder then its not the plug. could be coil, injector, engine mechanical. be careful not to drive to long because you could damage the catalytic convertor. thats why the check engine lamp flashes because its a catalyst damaging misfire.
I got a same problem in Holden Captiva diesel 2010 model as soon as you accelerate on traffic light the traction control light comes on engine light on dash, engine lack of power, turn the engne off for few seconds and goes ok but engine light stays on dash. Checked with the tech tool, it comes fuel metering code, can bus code... What it could be????. I've already changed fuel filter and did general service, still comes on. ANY IDEA PLEASE. OR I BURN THIS CRAPTIVA
P0068 Symptoms - Engine Light ON (or Service Engine Soon Warning Light) - Lack/Loss of power - Engine rough idle Possible causes - Large vacuum leak - Leaking air duct system - Mass Air Flow (MAF) poor electrcial connection - Manifold Absolute Pressure (MAP) poor electrcial connection - Faulty Mass Air Flow (MAF) sensor - Faulty Manifold Absolute Pressure (MAP) sensor - TP sensor not seated properly. - Faulty Throttle Position (TP) sensor. - Dirty throttle body When is the code detected? The Powertrain Control Module (PCM) monitors operation rationality check by comparing sensed throttle position to mass air flow readings P0068 DODGE Description The Powertrain Control Module (PCM) monitors a vehicle operation rationality check by comparing Throttle Position (TP) to Mass Air Flow (MAF) readings. If, during a self-test, the comparison of the TP sensor and MAF sensor readings are not consistent with the calibrated load values, the test fails and a diagnostic trouble code is stored in continuous memory.
If the service engne soon light is flashing, it means you have a hard failure, that is occuring at that time. If the car is shaking, it sounds like some sort of misfire. If you continue to drive it, you risk permanent damage to the engine, and catalytic convertors.
You have to time this perfectly or else it won't work.
Turn ignition switch on, after 3 seconds pump gas pedal five times. Once 15 seconds has passed hold pedal down for more than 10 seconds. The code will start to flash via the check engine light. Take your foot off the pedal. Watch it for a while, it will continue to flash the codes in a loop. To clear, hold the pedal down for more than ten seconds.
