Often the MAF sensor needs replacing, or possibly the coil packs, leads, spark plugs, K40 relay board (re-solder or replace), oil contaminated wiring, O2 sensor or crank angle sensor, disintegrated vacuum hoses, loose hoses, other.
The return hose for the heater core generally leads back the the water pump. The inlet for the heater core comes from the engine.
On 1.8T motors the engine speed sensor is on the lower part of the engine block on the driverside. It is held in my one Allen head bolt. It should have about a foot of cable which leads to where it plugs into the wiring harness of your car under the intake manifold.
It could be a number of problems. It could be the sensor is bad, it could indicate a fault with the alternator, faulty leads, faulty wiring... it depends on the situation.
Generally, the upper heater hose leads to the water pump.
The hose that leads to the water pump area is the return.
From the bottom of the motor contactor's heater block you connect the motor's leads to T1, T2 and T3. If the motor rotates in the wrong direction reverse any two leads on the bottom of the motor's contactor heater block.
If you look at the Drivers side of the motor you will see a wire that leads in under the intake. That wire leads to the knock sensor. The plenum, fuel rails,intake and thermostat housing will need to be removed to get to the sensor.
there are 2 oxygen sensors on your vehicle. The first is located close to the engine, in the exhaust pipe. Look for the wire that leads to it, that will help you find it. The second is right after the catalytic convertor. Again, look for the wire that leads to it. The both come out by turning it counter clock-wise. Disconnect your battery, unplug the wiring harness to the oxygen sensor and remove it. After you put the new one in, re-connect the wiring harnes and re-connect your battery, and your done.!!
Its under the cowl in engine compartment (close to windshield) in one of the heater hoses that leads to heater core. Black and white plastic with a small vacuum hose attached to the top.

P1646 is a fault in the heater or sensor of the upstream O2 sensor. It is the light grey plug on the firewall behind the engine and leads to the sensor unit itself on the rear bank exhaust pipe. A replacement sensor is between (UK) £65 and £120 depending on where you go. Beware of the generic 4 wire sensors as their specs are not quite up to Jaguar's. BTW. It's a b*tch to get to and you need a 22mm socket with a slot for the wires to go through.
The oxygen sensor on a 1996 Pontiac Grand Am is found near the catalytic converter. It will be place on the piping which leads to the catalytic converter.
For easy and quick identification of the leads, so that the user does not make mistake while connecting the leads.AnswerFor residential wiring, the earth wire rarely has a cross-sectional area that is larger than the line (not 'phase') or neutral conductors.
Just above the top radiator hose the leads into the engine.
It is important to have diagrams on hand of a cars parts. A free wiring diagram of this car can be found in the cars maintenance manual, or at an auto shop as a print off.
There is a faulty fuse that goes to the interior lights. There could also be a short in the wiring that leads to the lights.
The heater might blow cold air in a 2000 Silverado because the thermostat is sticking and not changing from cold to heat. The thermostat is usually located in a hose that leads from the radiator to the motor.
It depends what kind of sensor and how it is wired.Usually the "sensor ground" refers to the ground source at the sensor's plug. Usually that leads back to the ECM. Sometimes it's the threads where the sensor screws into the vehicle.If a wire brakes or corrosion builds up between parts the resistance can change, thus why measurements are taken from sensor ground.
It is located under the Upper Timing Belt Cover on the passenger side of the of the engine. You will see a wire running through the upper cover, this leads to the Camshaft Position Sensor. Another wire runs through the lower cover and this leads to the Crankshaft Position Sensor. Just remove the upper cover and with a flashlight you will see it bolted (2 bolts) next to the Camshaft Pulley.
Probably the vehicle speed sensor located in the transaxle extension housing, or a wiring fault up to the cluster are the cause of the problem. If the speed sensor is faulty, you will also have a fault code 15 stored. See the linked page for more information on how to get the codes. If there is no code for the speed sensor in memory, you may have a wiring fault. The speed sensor signal is carried on a white/orange wire in the left side connector on the digital dash. It splices to a wire of the same color leading to the connector for the traveler/navigator trip computers, and leads to a large 8-way connector forward of the left (drivers side) shock tower. From there it runs down to the distance sensor. Check continuity between the connector in the dash and the 8-way connector. If you have continuity, then your digital cluster may be at fault.
A good squirt of WD40 or similar over your engine wiring, plug leads and distibutor. It is a water repellant and will normally do the trick.
Depends on the wiring schematics of your car. If it's a short in a system which leads back to the ECM, yes, it could.
On the right side, beneath the intake piping that leads up to the throttle body, the O2 sensor is sticking out of the side of the exhaust manifold. No, it's on the left side, the driver's side.
On a Nissan Sentra GXE 1.6, the internal air temperature sensor is located in the air duct. It is the duct that leads from the air filter box to the throttle body.Ê
