Suzuki Swift 1.5 GLX Mechanical Help
#5
2007, M15 engine, with VVT. "M15a 1490 cc DOHC 16v MPFI VVT (Swift/SX4 ) "
first would be get the battery fully charged, even load test to see if it is 1/2 dead , if battery is so week that the starter runs slows, and is charged, that means the voltage drops below, 10v and the PCm will see that and set code for that,
its a warning to you that the battery was weak, (it does not know why only that it is or was) So any errors you see can be wrong, that old add-age that computers do not make mistakes fails, with power too low., (voltage drop)
Check fluids. brakes and oil levels and if milky that water contamination (doom)
then tune up at least. (uses spec. parts, not 4J or surface fire plugs, use what the OEM specs, (Suzuki) The NGK catalog also shows these facts.
try new spark plugs, or even look at them?
VVT, yes they are known to fail in this car, if it keeps popping VVT codes, then VVT bad or chain bad or now this, the chains have special tensioner, and is OIL pressure actuated. (these like to fail too , and often. )
the problem is , that tension is slack with engine off. so a loose chain now, means nothing, if the engine is not running, Some cars have lock up device in this tensioning device, that holds the chain tight with engine off, Ill not pretend i can see which kind you have nor year.
The PCM runs a model of the crank and cams, it simulates this model to the actual real, cam and crank and if the sensors show the cam is out of time, from the model at any time, it throws code for that, and is never wrong (battery not bad is first)
The retarded timing smacks of (bad vvt or dead tensionor)
is 81k , 81,000 miles or 81 kilo meters. 81km is the way to say Kilometers) not k. sorry but 81km is 50k miles so is near new engine, (and most do not have a bad chain ever if oil is changed say ever 7k miles.
If VVT error pops, a bad tension-er or bad VVT device is suspected.
or keep and eye on CMP or CKP errors (DTC's) cam or crank, if yes, then best work those first.
the vvt also as VVT solenoid device. that fails.
we do not have this swift car in USA, for sure not the M15 (2Liters yes )
the vvt valve may be packed in sludge from the last owner never changing oil, low oil levels on the dip stick hinted to me the PO was a slacker on service.

here is 2009 m16a. 3 photos added to gallery now. even simple wire fell off this solenoid or is damaged wire/connector , only close looking at it works.

see the tensioner here.
