Where is throttle position sensor located on 2000 honda passport

Your 2000 Frontier only has the one TPS sensor.

A camshaft position (CMP) sensor is typically only used as a reference for sequential fuel injection into the cylinders by the powertrain control module (PCM). Technically speaking, the 2000 Honda Accord doesn't have a CMP sensor, rather a cylinder position sensor (CYP). This should not be confused with the crankshaft position sensor (CKP) which is primarily used for ignition timing. There are also two different engine options for the vehicle being the 2.3L 4-cylinder engine and the 3.0 V6 engine. Sensor locations will be different for each option so it's important to first identify which engine is in the vehicle. The CYP sensor for the 2.3L 4-cylinder engine is located inside the distributor and is not serviceable; the whole distributor would need to be replaced. The CYP sensor for the 3.0L V6 on the other hand is located behind the left camshaft pulley on the timing belt back cover and is a serviceable part.

Hey DonAld, these are not hard to replace..( I do not know which engine you have..it makes a difference!! ).. take a PICTURE of where the current TPS os positioned and located... the radial (adjustment) location IS critical!!..

faulty throttle position sensor (TPS) replacements are easy to find & fit

Top under the intake is the camshaft position sensor,If this sensor fails the vehicle will still run and will even restart,The camshaft sensor is not causing the misfire.If it appaear as a code it is a rational code,you need to check for ignition misfire,

yes the tps could be the problem, but you need to use a scanner to determine the problem, don't just randomly replace parts, you could also have a problem with the air flow sensor, again use a scanner to determine the problem

Check the IAC (Idle Air Control) valve, it is located by the Throttle Body.

SOUND LIKE ALTERNATOR NOT CHARGING.HAVE IT CHECKED.YOU CAN TAKE IT TO AUTO ZONE THEY WILL CHECK ITS OUT PUT FREE.

It's under the hood, driver side, upper engine area attached on the end of the cylinder head

Classic symptoms of low fuel flow. I'd start by replacing the fuel filter (that's fairly cheap) and getting the fuel pump checked - it may be getting ready to conk out on you (not as cheap). Getting the injectors cleaned may help also.

If the fuel delivery system checks out, then the throttle position sensor may be bad.
