The MAF sensor is on the side of the air filter housing before the tube that goes to the engine.
It sometimes sends a signal to the computer that it is bad ; If you pullof the top of the air filter housing you can sometime blow into the honey comb to reset the trouble light.
or replacement is like $300.
On the driverside firewall is first place I would look
The ABS relay is in the relay box under the hood.
The outside tem sensor is located under the front of the car just under/front of the radiator. Dont know which relay it is.
The speed sensor wire is connected to the speed sensor and goes to the speed sensor relay switch. The speed sensor relay switch is connected to the computer by a separate wire.
The fan relay will be located in the PDB box in the engine compartment. The relay is controlled by the coolant temp sensor and the computer. Hope this helps.
The relay is not the same as the sensor. The relay is located next to the battery on the inner fender. It will have 4 or 5 wires running to it and will be bolted to the inner fender with one 10mm screw. It's a small black "box".
Not sure what a TCC (Torque Converter Clutch) sensor is. There is however a TCC relay and a TCC solenoid. The TCC relay is found in the relay/fuse center and the TCC solenoid is located inside the transmission.
Where is the ECCS RELAY LOCATED ON 1999 NISSAN MAXIMAType your answer here...
On a 1985 Chevy Celebrity the mass air flow sensor relay is located on the strut tower on the drivers side of the car. It is behind a cover. The fuse for the mass air flow sensor is also there with the relay.
There isn't one, its wired into the ECM.
