HO2S and O2 sensors are sold as units and can be obtained from a service dealer spare parts or from good auto spare parts shops. There is a special socket that should be used to remove and install the units as it is necessary not to twist or load up the wires for the units. Units can be genuine or generic depending on what you want to pay for them but be careful of generic units as you may have to get the ECm reprogrammed with a scanner to get the different settings recognized.

Where is the camshaft sensor located on a 98 Honda Accord 2.3L engine


It is a CYP sensor, and it is located in the distributor. It is not replaceable as a separate unit. If it is faulty, you must replace the entire distributor.

I need to find the crank shaft sensor on my 91 honda accord 2.2 16 valve. if you would please send me a diagram of where it is.


It's located inside the distributor. It would probably be better for you to change out the entire distributor that to go digging around inside it. The cost of an entire distributor, as opposed to changing all the sensors located inside, it's cheaper to replace the entire unit.The other sensors in there might also be on their way out, being so old.

Direction on how to replace coil pack 1988 pontiac grandam


The coil pack rests on the back of the engine, under the intake manifold. Make sure the engine is cool. Follow the plug wires to their ends and you'll see the coil pack. Mark the wires with tape and number them 1-4 so you know the order the plug wires are in. You'll need to remove the entire ignition pack to replace the coils. Three 10 mm bolts hold it in place. Remove the marked plug wires from the pack, unplug the two wire connectors. I worked the pack out from underneath the care. There is a crank sensor on the back of the unit - be careful not to break it as you remove the unit. Take the pack to a table and remove the 4 small nuts that hold the coils in place. Clean all the connectors and apply some dielectric grease to all the electrical connectors. Add some grease to the o ring on the crank sensor and clean all the other parts. The 4 bolts that hold the coils on can only be replaced by pulling the entire unit. Install the new coil spade connectors into the base, being careful to align them properly. Snug down the 4 small nuts that hold the coils on while holding the bolts that secure them with your fingers until the get tight - be careful that the bolds fit into the recesses that hold them squarely. Replace the unit in the car as you removed it with the three 10 mm bolts. Be sure to follow the numbers on your plug wires as you replace them. Reconnect the two wire connectors after cleaning the contacts. Replace the ground to the upper right bolt of the pack. Now would be a good time to replace the plugs and plug wires as well! Took me about 2.5 hours.

Replaced my tires and two of my tire pressure sensors snaped and now after driving for about 10 minutes or less the service tire pressure system keeps comming on, but when i hit the step buttom it goes...


It sounds like the problem I had - I had bought replacement valve stem caps (metal). When I went to take them off to replace the tires, they were stuck and snapped off. Apparently, the valve stems for the auto-pressure monitoring units are alloy and not stainless steel and the replacement caps reacted with them and got corroded and stuck on. Unfortunately, Jeep does not just sell the individual valve stems for these units - you have to purchase the entire pressure sensor unit for the wheel (~$200 apiece). I ended up replacing all 4 sensor units for the wheels, and will leave the plastic caps on them from now on!

Replacing a Temparature sensor


Locate thermostat. Next to it should be the temp unit. Remove the unit, check with an ohm meter. If defective take to auto shop and obtain one just like it. To replace wrap with some pvc tape and reinstall.

On a 04 camry with 2.4 ltr engine, can I replace just the throttle position sensor or do i have to replace the entire throttle body? The engine code said faulty throttle body.


I think the terms "Throttle Positon Sensor", TPS and "Throttle Body" can be misleading at least in regards to the 04 Camry.

My 04 Camry gave a diagnostic reading of P2121 for my problem "Throttle PEDAL position switch D circuit". However, we changed out the complete Throttle Body/TPS (Toyota Part #22030-0H020) that did NOT fix problem.

The 04 Camry TPS Electronic Module "Throttle Positon Sensor" is factory assembled and riveted to the side of the throttle body. The only way to service/inspect it would be to cut off or drill out the rivets. Not sure you could open the darn thing if you got it off, but that seems to be the only way Toyota sells them!!

Hopefully a new Throttle PEDAL Position Sensor (Toyota Part # 78010-33010 PEDAL ASSY, ACC)
will fix it. This is located under the dash near the accelerator pedal.

So, now I would recommend FIRST to replace the "Throttle PEDAL Positon Sensor" (it is much, much cheaper) and then the Throttle Body/TPS assembly!! Unless of course, you get a diagnostic code as you did for "faulty throttle body!!

Speedometer doesnt work, is there a fuse or a sensor? & where do i find them.


More likely on a car this age it will be a physically spinning speedo cable inside a rubber sleeve that runs from the back of the speedometer to somewhere on the gearbox on the final drive. They do snap accasionally and can be a bugger to replace, get any kinks in the new one and it will snap again. Take instrument console out and have a look at the back of the speedo you'll soon know.

Guages on 87 olds cutlass are not working properly. fuel does not work, temperature works but goes strainght to hot as soon as the car warms up, amp gueage discharging oil pressure not working


Hi, you will have to replace all sending units for these gauges in order to restore them to there original state. i will list the sending units and there respective locations below.

1. Fuel gauge sending unit- you will need to replace the fuel sending unit on your Olds. its located inside the actual fuel tank. there's a floater attached to this Assembly and , its broken. you will have to replace the entire assembly. you will also have to drop the fuel tank to access it as well.

2. Temp guage-- normally when this guage starts to malfunction, its because of a bad coolant temperature sensor. Inspect the sensor's wires and connections. ECT (engine coolant temperature) sensor problems are often caused by faulty wiring or loose or corroded connections rather than the failure of the sensor itself. If the wires or connections are bad, replace them. If you think the sensor is defective, it should be tested.

This sensor is located Under hood, center, upper engine area, front of carburetor, passenger side of water outlet, mounted in intake manifold.

3. Amp gauge --- OK, this can be caused by a bad voltage regulator. i would also trace every single wire from the amp gauge to the sensor and regulator. check for corroded connectors and contact clips. replace any wire that may seem worn.

4. Oil pressure gauge-- This gauge will malfunction if the Oil pressure switch is faulty or not working. This is an Information relay unit for the indicator light or gauge on instrument panel. It contains a diaphragm that responds to changes in oil pressure. When the oil level is over a pre-set limit, the diaphragm opens the switch, turning off the light. When level is below the pre-set limit, the dash light comes on. In later model cars, if the oil pressure drops, the switch turns off the fuel pump, to stop the engine and limit damage to internal parts. Oil pressure switches can be grouped into two categories, units for electrical gauges and for mechanical gauges. If this switch is defective, it will have to be replaced. Once replaced, it will fix the dead oil gauge.

This device is located Under the hood, passenger side, front engine area, mounted rear of water pump. If the wires are worn or there is an oil leak near the switch location, replace it.

Inspecting all the above areas and replacing parts if needed, will fix your gauge issues.

Please rate and god bless:)
