Check U1602 Engine Code
When you check engine light came on code U1602 the reason should be . However your vehicle's manufacturer may have a different definition for the U1602 OBD-II Diagnostic Network (U) Trouble Code. So you should chech it on our car models.
Theoretically you can drive for a few weeks or even months with a broken MAF sensor. You will notice a decrease in gas mileage and over time the car will eventually start stalling a lot. At a shop, the replacement cost is between $200-$300 depending on the car, but that's usually the cost of parts because the labor is relatively simple.
U1602 Possible Solution:
The crankshaft sensor signals the fuel injection computer or the ignition control when the cylinders are firing. This causes the ignition coil to provide a spark and the injector to inject fuel into each cylinder at the right time.If either sensor isn't working correctly, the car will run rough and the engine will be less efficient. In later car models, the car's computer can usually keep the vehicle running, but the engine warning light on the dashboard goes on to warn the driver.
U1602 Code Meaning :
|OBD-II Diagnostic Network (U) Trouble Code For Engine||Fuel And Air Metering||Fuel Temperature Sensor B Circuit Range/Performance||Cold Start Injector 1 Malfunction||Glow Plug/Heater Circuit 'A' Malfunction|
