  1. The observation with your vehicle implies mechanical malfunctions likely caused by insufficient, clogged, or burnout lubrication fluids. Since the component parts experiencing malfunction are observable at significant vehicle areas like power drive trains, several conditions are likely factors to driver's suspicion. For example, the drive train of significant mechanical sprockets linked at joints making propulsion possible with the control lever situated at drivers seating area is significant reason of concern. First, the driver's lever control functions hydraulically as modern improvement made possible with fluid lubrications, and several absorptions chambers. Once, an engineered hydraulic mechanical lever is realized to dispense manual contact requires inspections. First, a mechanical inspection to ascertain the conditions of constutuents providing hydraulic should be made on the vehicle. The possible outcomes include findings of an absence of faulty turbines implying no wear had occurred. Second, the observation findings may ascertain a burnout fluid that may require replacement procedures. For example, burnout hydraulic fluids usually may require cleaning draining, cleaning the residue slug from turbine areas making possible replacement of newer fluids. Hydraulic fluid conditions usually may require resistant variety that performs under overexerted conditions. For example, the fluid type may vary depending on the task requirements of the vehicle. Also, the type of condition expectations of the vehicle would require frequent hydraulic inspections.

    1. Auto inspections of the vehicle may produce results contributing towards restoration. For example, the auto technician makes the evaluation as separate arrangement from which problematic areas are ascertainable. The result findings are documented as diagnostic draft plans from which repair authorizations are achievable. At which point, diagnostic without repair requirements would least requires any further procedures. However, once the vehicles diagnostics produce result requiring expert vehicle repairs, the next sequence of procedures are initiated. First, vehicle repairs require constituent components either permanent parts or depleteable resources constituents prior to workshop initiation plans. Auto technician diagnostic plans would usually contain the damage of the vehicle. A decision to commence restoration of the faults would produce estimate drafts in parts repaired for either replacement acquirable, leasable or alternately. The next sequence includes calculations estimates in resources that would be required contributing towards entire workshop restoration process procedures.
    2. Usually an evaluation auto expert may necessarily not have resource constituents for restoration to occur. An alternative arrangement includes acquiring component parts specified on diagnostic charts from elsewhere. Meanwhile the arrangement may be with the evaluations technician as repairs fellow once components were amassed. A diagnostic technician may provide the means to acquiring components when engaged as the repairs person however. Also, the type of auto restoration mode may require workshop environments with several signifance advantages. First, an auto workshop would usually provide environment where extensive tasks are achievable. For example, the auto repair environments require least obstruction to achieve success especially with tasks that may require undivided external obstructions with delicate technical process procedures. Second, auto repairs require workshops where installment facilities including huge to work box tools are prevalent to achieve repair works. Third, auto workshops provide the exclusive environment to achieve vehicle restoration.
    3. Usually an auto damage inspector would require fees for the expertise rendered as alternate arrangement. A result produced requiring pursuit arrangements may cost alternatively. For example, acquiring parts for that may be required to contribute towards restoration of damage decided from an auto evaluation expert is achieved at an alternate location. Auto parts stores would usually be a separate entity from the mechanical expert. Also, once the constituent parts for restoration the vehicle has been acquired, the same technician’s expertise may be requested as separate cost termed workmanship fees. An alternate auto expert’s consultation to restore the vehicle with the diagnosis plan, acquired parts, would involve separate cost arrangements.
    4. Usually, the likelihood of where vehicles damage requires workshop area only acquirable at separate arrangement may have cost fees. The condition attachments of the workshop may contribute towards cost fee explainable. For example, a leased workshop may require for auto technician to perform expediently else additional cost are incurred to the vehicle owner. Also mentionable situations where technician fee cost increase due to schedule arrangements found unsuitable either as working elsewhere inconveniently or being hurried to achieve report works are only mentionable conditions with auto workshop as alternate arrangements from the technician expert’s responsibility.
    5. A damaged auto vehicle may require several arrangements contributing towards repairs least mentioned in technical responsibilities. For example, moving damaged vehicles between places prior to restoration may have been separate arrangement. Acquiring component parts that contribute towards restoring the vehicle is alternate arrangement. For example, component parts situated elsewhere requiring acquisition from the situation of vehicle or workshop, and technician expert contributes towards fee costs as amongst restoration conditions. Also requiring alternate arrangement prior to auto workshop commencement is fee cost calculations. An expert consultation may be required to ascertain the entire process contributing towards restoring a dame vehicle. For example, the documentation of the entire process has two advantages. First, throughout until the repairs are achievable, the documentations expert provides the details understood as feasible to achieve repairs. Second, the documentations expert provides the details as necessary processes until repair s are achievable. For example, the documentation is similar with accounting purpose requirements, record keeping, or even feasibility analyst for projects of individuals or businesses.
    6. The transportation efforts constitute in the repairing vehicles includes logistical resources that contribute towards restoring the broken equipment. Usually, consulting with an external entity as transport management responsibility has conditions. An example is consulting with towing transport establishments. A tow transport has several arrangements. Usually, the machine type requested has cost implications. Where size is significant factor in tow trucking. The larger a vehicle requires extraneous cost fees. Second, the responsibility request from the tow trucking has several requirements. For example, a demanding task from tow transport command huge fee costs. However, a rate fee makes the truck vehicle available. Several constituent arrangements of durational service request from the trucking establishment requests fee costs. Tow trucking establishment may have arrangement requirements contributing towards cost fees. Several examples are provided on acquiring transport for auto restoration peruses. First, the durational request of the truck ma have a charge cost where extensive duration has cost fees separate than least spans. However, the charge for acquiring truck transporting has fee cost separate from unforeseeable conditions. For example, requesting the truck may have transportation component arrangements where further off destination chargers from truck vicinity area are mentionable. Also, truck constituents like gasoline arrangements handled separately. The type of trucking establishment may require the costs of chauffer also conditional. For example, trucking may allow for requester to operate the device, else acquiring an alternate operator the device would become necessary commanding charge fees and costs
    The vehicle’s mechanical levers are joined together only separated at ball socket areas. Every ball socket area is lubricated to minimize wear though require durational inspections from which modifications may be achieved. The vehicles mechanical parts however least require replacement unless were malfunction with appropriate recommendation of change as solution. Mechanical parts however function with fluid lubricants that require replacement duration ally. A mechanical fluid however may last an entire expected length until the specified reinsapction without a situation of harm occurring prior to regular auto service inspections. However, the significance of mechanical fluids are providing lubrication for moving parts where the vehicle benefits in motion generation while the drivers acquire resourcefulness for the most part, and pleasant ride as contributory experience with proper functioning constituent components. Several mentionable factors makes vehicles component require frequent reevaluations. First, the type of conditions that are exerted on the vehicle determines the evaluation requirements. For example, mechanical power trains of a vehicle are overexerted with tasking functions either hauling, or repetitive engagement functionalities. Usually vehicles with dual functionalities may require separate checkup since over exerted parts acquire wear compared with remaining least enagagerable components. The components of the vehicle usually have durational inspection requirements. However, once observing malfunction requires evaluation prior to regular durational service inspections.

How do i change the throttle positioning sensor on my 2002 Kia Optima?

Changing the throttle position sensor (TPS) on your 2002 Kia Optima is a fairly straightforward task, but it's crucial to approach the process with care. Below are general steps to replace the TPS on most vehicles. However, always refer to the specific service manual for your car to ensure you're following the correct procedures.

Tools and Materials Needed:

  • Screwdriver or socket set (depending on the type of fasteners used)
  • A new throttle position sensor (ensure it's the right part for your vehicle)
  • A digital multimeter (optional, for testing the old sensor)
Steps to Change the Throttle Position Sensor:
  1. Safety First: Disconnect the negative terminal from the battery. This ensures you won't accidentally cause any electrical shorts or get shocked while working on the vehicle.
  2. Locate the TPS: Find the throttle body on your engine - it's usually located between the air filter box and the intake manifold. The TPS is a small sensor, often positioned on the side of the throttle body and connected to the throttle plate shaft.
  3. Inspect Electrical Connections: Before removing the TPS, check the wiring and connections for any signs of damage, corrosion, or wear. If you find damaged wires, they'll need to be addressed as well.
  4. Remove the TPS: Using the appropriate tool (screwdriver or socket), carefully remove the screws or bolts holding the TPS in place. Some vehicles might have a clip that secures the sensor. If so, carefully detach it.
  5. Install the New TPS: Position the new TPS in place, ensuring that it aligns properly with the throttle plate shaft. Attach it using the screws or bolts you removed earlier. Be cautious not to overtighten as you could damage the new sensor.
  6. Reconnect Electrical Connections: Plug the wiring harness back into the new TPS. Ensure it's securely connected.
  7. Reconnect the Battery: Reconnect the negative terminal to the battery.
  8. Test the Installation: Start the car and let it run for a few minutes. Pay attention to any unusual behaviors, such as erratic idling or poor acceleration. If you have a digital multimeter and know how to use it, you can check the TPS's voltage to ensure it's working correctly.
  9. Clear any Engine Codes: If you had a check engine light due to the faulty TPS, you might need to clear it using an OBD-II scanner.
  10. Test Drive: Once you're sure everything is in order, take the car for a short test drive. Monitor for any issues with throttle response or engine behavior.
Remember, while these are general guidelines, there may be specific details or steps unique to your 2002 Kia Optima. Always consult the vehicle's service manual or consult with a professional mechanic if you're unsure about any part of the process.

My 2004Kia Spectra will not blow out heat or air

Sounds like the fan is not working. Does it blow air on any setting? If only on high, your resistor is faulty. If not, the motor, switch or fuse/relay may be at fault. Check these out first!!

I need to know where on the motor the trottle position senser is located on a 2006 kia optima lx v6

All throttle position sensors, have to be on the throttle body,
on order for the computer to recognize throttle position & convert
to throttle plate angle %

Any code you get, on an OBD2 System, doesn't mean to change parts

The codes are used to follow manufactures charts, to diagnose
the code fault, somewhere in one of the vehicles systems

On all vehicles if you follow the air intake, from the filter to the
intake manifold,you get to the throttle body

Given your question,I suggest you leave the diagnosing to
an experienced person

Need how to set timing belt on kia optima

I had 2006 kia optima 2.4 liter LX, I drove 150000 miles plus, it was over 100,000 miles I changed timing belt, and AC belt, alternator belt is still ok, but it was my fault, I did not change crank shaft balance belt, it next to timing belt, this very important, timing belt and crank shaft balance belt must change same time, you set all mark the same positions, you can see all clear marked
if you had OBD2 scanner is helpful to read all faulty codes if you do it your self repair
if you have any problems about KIA optima, please post on any websites, to share some ideas to other KIA optima owners, like me, I change oil every 2500 miles to make my optima runs smoother
automatic transmission fluid change every year if you put high mileage on your car, optima had hard time to find it own part some time, radiator hoses are still good condition and had hard time to find in any auto part stores in my home town, good luck and thanks for sharing.

Hi. I have a 2002 KIA Optima, and I believe the Throttle Position Switch (TPS) is faulty. Could this cause other electrical problems, such as the radio coming on when I hit a bump? Thanks, Joice

no ! if the sensor is faulty then it will be noticed by poor engine response or slow idle speed!
radio may be loose wire or mounting to earth!
Cheers Rob

cold start sensor is faulty. basically when you start a car from cold,the sensor mixes the air and fuel to allow more fuel to air ratio to start the car. as the engine warms the air fuel mixture weakens to give a economical fuel consumption.hence your car starts warm.
