How many Sensors are on a 4runner, can anyone name some

i want to know beacause ive had problems with my runner and need to know what sensors are working

thanks

 

Here are some common(ish) sensors/parts that you should check:

AFM
O2 sensor
TPS
Coolant temp sensor

Also, check for vacuum leaks...

 

umm...

throttle position sensor
air flow meter
intake air temp sensor
coolant temperature sensor
cold start time switch
distributor / hall effect
knock sensor
EGR temp
O2 (could have 1 or 2)
Neutral safety (clutch) / park / neutral

what did I miss?

 

How bout that damn sensor that makes that high pitched sound when the driver's door is open with the key in the ignition...

 

Engine Control Input Signals
Water Temp
Intake Air Temp (AFM)
Oxygen Sensor
RPM Signal (Crankshaft position)
Throttle Signal (TPS)
Vehicle Speed
A/C Switch
Battery Signal
Intake Air Volume (AFM)
Stop Light Switch
Starter Signal
Engine Knock
4WD Signal

There are obviously others for transmission (gear selector, transfer case, etc.), braking (brake fluid level), oil pressure, parking brake switch, etc.

 

too many sensors what happened to the days when there was ONE or TWO sensors? where you jumped in the back of your buddys truck and went cruisin, where you checked your idle speed with the door hanging open?

 

oh man the door open trick i hane not heard that one i a long time now a days you cant do that anymore tomany things to go wrong
