Code p0105 refers to manifold absolute pressure (MAP) sensor/ barometric pressure (BARO) sensor--circuit malfunction===causes --wiring---MAP sensor--BARO sensor--ECM
code p0110 refers to intake air temperature (IAT) sensor--circuit malfunction===causes---wiring ---IAT sensor--ECM
code po115 refers to engine coolant temperature (ECT) sensor--circuit malfunction===causes---wiring--ECT sensor---ECM

SOURCE: The codes given are p0105 and p0110 and I cant

There are a couple things I recommend that you take the time to understand here.

Diagnostic Test Code (DTC) P0105 is defined by SAE J2012 as "Manifold Absolute Pressure/Barometric Pressure Circuit"

(DTC) P0110 is defined as "Intake Air Temperature Sensor 1 Circuit"

The first thing is that Diagnostic Test Codes (DTCs) commonly referred to as "fault codes", NEVER tell you what parts to replace. These codes are designed to point the auto repair technician to the proper diagnostic testing routine in order to pinpoint the actual cause of the failure. If you do not have access to the diagnostic test routines published by the vehicle manufacturer for the purpose of diagnosing these faults, as well as the proper equipment required to perform the steps in the diagnostic routines, you may be in for an expensive "parts-replacing-no-joy-ride". However, spend your time and money as you wish.

The next thing is that the ENTIRE code definition needs to be taken into consideration. Please note that these are CIRCUIT codes. A sensor cannot function any better than the circuits that connect it to the rest of the engine control system. The circuits to these sensors must be properly tested in order to determine the exact CAUSE of the DTCs setting. - or as mentioned above, you can just replace all the parts associated with these fault codes and hope you get it right.

Another little piece of information you might find helpful is that both of these sensors share the same reference voltage from the engine computer. Fixing ONE of them has a pretty good chance of fixing BOTH of them. Then again, there might be two seperate problems.
However, you will have no way of knowing if it is one or both and if it is only one, then WHICH one actually needs to be fixed without proper diagnosis.

With all that said:
The MAP/BARO sensor is located at the left rear of the engine compartment, near the brake fluid reservoir.

The IAT sensor is located at the left front of the engine compartment, in the air intake duct near the battery

there is two sensors that those code refer too. The map sensor, and the iat sensor. and both would have an effect on gas mileage. Both sensors would just make the car run a rich mixture.

SOURCE: I need a wiring diagram for 1999 Toyota Noah

Something must be drawing the battry flat. Probably something you can't see. Start by removeing glovebox light & boot light & see if the current drain stops. If it does one of those lights are staying on.

Toyota Noah with 1AZ FSE engine misfiring in cylinder 1 and 4 but 2 and 3 working properly

According to the computer, it seems the Noah was not made for USA market however, in this country, the first thing to check is the spark plugs themselves; and after that, the "coil pack", which is the individual coil for each spark plug.
Then test the distributor.
God bless your efforts.

NO POWER TO SPARK PLUG toyota noah 2003

The computer uses both camshaft and crankshaft position sensors to time the spark to cylinders. You really need an obd scanner that has real time data to see if the sensors are reading rpm when you crank the engine.

Trouble code p0135, p0303, and p0115

your guessing and then ask us to guess?
why not look in the FSM , it answers that.
or at
im there now...

303 is cylinder #3 Misfire. can be caused by 3 things. (ask)
135 is front oxygen sensor heater bad, or wires to are BAD.
115 ECT coolant sensor reads shorted. (beyond north pole cold)
bad ECT , bad wires to it or ECU power it , wrong, dead or weak.

fix 115 first. , then 135 (both are hard failures, DEAD)
last : ever do a tune up, every?
303 can be , just a bad spark plug , injector or burned valve.

the tests for both 115 and 135 , are in the FSM and presented
in fact the tests are same for all cars. 1996 and newer in uSA.
are you handy?
or just want us to take a wild guess.
here is my wild guess.
1: ECT wires shorted.
2: front 0xy sensor is bad. replace it.
3: a tune up fixes, 303, (new spark plugs,wires cap and rotor) and air/fuel filters. like magic the #3 stops misfiriing... (your lucky day not a burned valve and $1500 fix)
all my guesses are wrong, but felt id do it to show the folly.
better is the RTM read the manual, do the tests and find truth.
we never guess. we do that tests.

this is a common code on nissans and it is due to the O2S1 sensor reading that the cat is operating below threshold-can be
- Three way catalyst converter Bank 2
- Engine Control Module (ECM) Program
- Exhaust tube
- Intake air leaks
- Fuel injectors may be faulty
- Fuel injector leaks
- Spark plugs may be faulty
- Improper ignition timing
- Engine Control Module

most of the time it can be corrected by a nissan dealer, by reprogramming the stringent maps in the ECM, and the put out bulletins saying they would cover it if under 80,000-8 years, so that is not going to work-check the other possible issues then make calls to the dealer and see if you can get them to treat you like a future customer instead of a bother.
