a small rubber vacuum pipe connecting to the injector system / inlet manifold. Sometimes this pipe perishes and allows air to enter thus decreasing the vacuum. The engine then cuts out. It's simple to check and replace the tubing where necessary. You may also notice the engine cutting out when traveling at speed and one suddenly slows down.

2004 Nissan Altima 3.5L BATTERY LIGHT went on during 15 minute drive. Next day car "died" while idling after a 20 minute drive. BRAKE WARNING LIGHT & BATTERY LIGHT on prior to full electrical failure.


Start with checking the alternator voltage with a multimeter. With the car off check the voltage in the battery which should be holding 12v charged less if flat of course then start the car and test the battery again. If the alternator is good you should be getting a reading of 14 to 14.5 v if it's the alternator it'll A) not put any charge into the battery or B) be a very low voltage being anything under 13.5 v

What is causing the battery to drain?


Running the car will drain the battery it if it's not charging ! An if your charging light is on it isn't charging ! Did you check power an grounds on the alternator ? There is a single heavier wire on the back of the alternator, this should have battery voltage ! You may want to take this to a ASE certified repair shop !
Functionality
With the ignition switch in the RUN position, voltage is applied through the warning indicator I circuit 904 (LG/RD) to the voltage regulator. This turns the regulator on, allowing current to flow from battery sense A circuit 35 (OG/LB) to the generator field coil. When the engine is started, the generator begins to generate alternating current (AC) which is internally converted to direct current (DC). This current is then supplied to the vehicle's electrical system through the output (B+) terminal of the generator.
Once the generator begins generating current, a voltage signal is taken from the generator stator and fed back to the regulator S circuit 4 (WH/BK). This voltage feedback signal (typically half the battery voltage) is used to turn off the warning indicator.
With the system functioning normally, the generator output current is determined by the voltage of the A circuit 35 (OG/LB). The A circuit 35 (OG/LB) voltage is compared to a set voltage internal to the regulator, and the regulator controls the generator field current to maintain the correct generator output.
The set voltage will vary with temperature and is typically higher in cold temperatures and lower in warm temperatures. This allows for better battery recharge in the winter and reduces the chance of overcharging in the summer.
Battery Positive Output (B+) Circuit 38 (BK/OG)
The generator output is supplied through the battery positive output (B+) terminal on the back of the generator to the battery and electrical system.
I Circuit 904 (LG/RD)
The I (ignition) circuit 904 (LG/RD) is used to turn on the voltage regulator. This circuit is powered up with the ignition switch in the RUN position. This circuit is also used to turn the charging system warning indicator on if there is a fault in the charging system operation.
A Circuit 35 (OG/LB)
The A (battery sense) circuit 35 (OG/LB) is used to sense battery voltage. This voltage is used by the regulator to determine generator output. This circuit is used to supply current to the generator field (rotor). The amount of current supplied to the rotor will determine generator output.
S Circuit 4 (WH/BK)
The S (stator) circuit 4 (WH/BK) is used to feed back a voltage signal from the generator to the regulator. This voltage is used by the regulator to turn off the charging system warning indicator. The S circuit is fed back externally on external mounted regulator generators.
Visual Inspection Chart Mechanical Electrical
  • Battery case, posts, hold-down clamp, cables and connections
  • Generator drive (serpentine) belt for condition and tension to make sure there is no slip between the belt and the pulley. For additional information, refer to Section 303-05 .
  • Battery charge
  • Generator pulley
  • Battery junction box (BJB)Mega Fuse
  • Battery junction box fuse:
    • 11 (20A)
  • Central junction box (CJB) fuse:
    • 30 (30A)
  • Circuitry
  • Charging system warning indicator
  • Cables
  1. Check the operation of the charging system warning indicator lamp (instrument cluster). Normal operation is as follows:
    • With the ignition switch OFF, the charging system warning indicator should be OFF.
    • With the ignition switch in RUN and the engine off, the charging system warning indicator light should be on.
    • With the engine running, the charging system warning indicator light should be off.
  1. Verify the battery condition. Refer to Section 414-01 .

    • The charging system warning indicator is on with the engine running (the system voltage does not increase)
    • Circuitry.
    • Voltage regulator.
    • Generator.
    • GO to Pinpoint Test B .
    Your whole problem is the alternator is not charging , a couple tests with a volt meter would tell you !

I changed my cv joint in my hyundai avante 2001 then the ABS TCS lights turns on and abs doesnt work


Check that the brake assembly has been correctly refitted. Secondly check specifically the ABS sensor/s. Is there a setting to be set on these sensors during assembly? Has this been correctly fitted and set, or is the sensor/s now damaged?? It may also just be that the ABS computer system requires resetting after each reassembly!

What is the 1999 kia sportage ring gear torque settings


  1. Torque
    • Torque is a measurement tool that shows a vehicle's ability to tow and accelerate. The 2000 Sportage generates 135 ft-lb of torque when measured at 4,000 rpm. It tows up to 2,000 lb.
    Power
    • The 2000 Sportage features a 2.0-liter I4 engine that produces 130 horsepower at 6,000 rpm. Five-speed manual overdrive transmissions are standard for all models, but the four-door models offer the option of getting a four-speed automatic overdrive transmission instead. The compression ratio is 9.1 to one and the engine displacement is 1,991 cc. The bore and stroke are 3.26 and 3.62 inches.
    Fuel
    • All manual versions get 20 miles per gallon in the city and 23 mpg on the highway. The automatic four-wheel drive models get 19 mpg in the city and 22 mpg on the highway. The automatic two-wheel drive models get 18 mpg in the city and 21 mpg on the highway. The two-door model has a 14-gallon fuel tank and the other models have a 15.8-gallon fuel tank.
    Measurements
    • The two-door Sportage is 156.4 inches long with a wheelbase of 92.9 inches. The four-door versions are 170.3 inches and the wheelbase is 104.3 inches. All versions are 68.1 inches wide and 65 inches tall. The front and rear tracks are both 56.7 inches. All versions sit 7.9 inches off the ground. The two-wheel drive, four-door versions weigh 3,186 lb if manual and 3,230 lb if automatic. The two-door, two-wheel drive model is 3,108 lb. The two door, four-wheel drive model is 3,230 lb. The four-door, four-wheel drive models are 3,352 lb if manual and 3,396 lb if automatic.

Warning light check engine light turns on, sometimes after 10-20 minutes drive. The engine is perfectly OK. Indicator light is off after the car has "rested" during the night.


You may have a sensor malfunction. Have a mechanic run the codes and see if there are any stored in the computer. Just because the engine runs OK now does not mean it will continue to do so. The reason the light goes off after the vehicle has set over night may be due to the vehicle not sensing the issue after the long passage of time, until you begin driving again.
