P-0102 and P-0113 are mass air flow and intake air temp codes, the P-0136 is an Oxygen sensor code. Before you do anything, check for debris in the Mass Air Flow Sensor, it's small black box with electrical wiring connector that is screwed into the intake air tube, between the air box and the intake manifold. Undo the screws, remove the sensor, and, with a flashlight, and look down inside it for debeis, or broken wires inside it. If it's dirty, it could throw a P-0136...Comment back on what you find; hope this helps, and thanks for choosing FixYa!

SOURCE: my 2000 ford focus has codes p0102 and p0113 whats

P0102 - Mass Air Flow (MAF) Circuit Low Input
The MAF sensor circuit is monitored by the PCM for low air flow (or voltage) input through the comprehensive component monitor (CCM). If during key ON engine running the air flow (or voltage) changes below a minimum calibrated limit, the test fails. MAF sensor disconnected
MAF circuit open to PCM
VPWR open to MAF sensor
PWR GND open to MAF sensor
MAF RTN circuit open to PCM
MAF circuit shorted to GND
Intake air leak (near MAF sensor)
A closed throttle indication [throttle position (TP) sensor system]
Damaged MAF sensor
Damaged PCM
A MAF V PID (MAF PID) reading less than 0.23 volts (Refer to equivalent grams/second chart in GO to Pinpoint Test DC ) in continuous memory or key ON and engine running indicates a hard fault.
P0113 - Intake Air Temperature (IAT) Circuit High Input Indicates the sensor signal is greater than Self-Test maximum. The IAT sensor maximum is 4.6 volts or -50°C (-58°F). Open circuit in harness
Sensor signal short to power
Damaged sensor
Improper harness connection
Damaged PCM
IAT V PID reading greater than 4.6 volts with key ON and engine OFF or during any engine operating mode indicates a hard fault.

SOURCE: 04 Pontiac Vibe bad gas mileage without a code and then the p0420

that code is from having the plugs wires reversed as you did and the o2 senors regrsitered the overload on gas emmions once you remove the battery cables for about 5 minutes and then recconect and run the engine it should be okay

SOURCE: diagnostic codes

P0102 OBD-II Trouble Code - Mass Air Flow (MAF) Circuit Low Input

What does that mean?
Basically this means that there is a problem with the Mass Air Flow (MAF) sensor or circuit. A more technical description would be that the MAF circuit had lower than expected voltage (air flow). Other MAF sensor circuit DTC trouble codes are P0100, P0101, P0103, and P0104.

Symptoms
You will likely not notice any serious drivability problems, although there may be symptoms such as a general decrease in power or sluggishness.

Causes
A code P0102 may mean that one or more of the following has happened:
* The MAF may be disconnected, or a wiring connection may be bad
* The MAF may be dirty or otherwise contaminated (Note: if you use a reusable oiled air filter, be careful not to apply too much oil or that can contaminate the MAF).
* The MAF sensor may be faulty
* The vehicle computer may be faulty (very rare)

Possible Solutions
The simplest thing to do is to reset the code and see if it comes back. Then start with the cheapest, easiest repair procedures:
* Verify that the Mass Air Flow Sensor wiring is connected properly and that there are no broken / frayed wires.
* Inspect for any air leaks near the MAF sensor.
* Take the MAF out and clean it using a spray cleaner such as brake cleaner or electrical contact cleaner. Be gentle with the sensor.
* Check the voltage of the MAF sensor (refer to a repair manual for vehicle specific information)
* Replace the MAF sensor.


P0113 - Intake Air Temperature Circuit High Input

What does that mean?
The powertrain control module (PCM) monitors the temperature of the air entering the engine. The PCM supplies a 5 volt reference voltage to the Intake Air Temperature (IAT) sensor. The IAT is a thermistor that varies resistance based on temperature. As the temperature increases, resistance decreases. Low temperature results in a high signal voltage. When the PCM sees a signal voltage higher than 5 volts, it sets this P0113 check engine light code.

Potential Symptoms
There will likely be no symptoms other than illumination of the Malfunction Indicator Lamp (MIL - Check Engine Light / Service Engine Soon).

Causes
A code P0113 may mean that one or more of the following has happened:
* Internally failed IAT sensor
* Faulty connection at IAT sensor
* Open in IAT ground circuit or signal circuit
* Short to voltage in IAT signal circuit or reference circuit
* IAT harness and/or wiring routed too close to high-voltage wiring (e.g. alternator, spark plug cables, etc.)
* Faulty PCM (less likely but not impossible)

Possible Solutions
First, if you have access to a scan tool, is there an IAT reading? If the IAT reading is logical then the problem is likely intermittent. If the reading is less than -30 degrees, unplug the connector. Install a jumper wire between the harness connector signal and ground circuits. The IAT temperature reading on the scan tool should be maxed out at the high end. For example it should be 280 degrees Farenheit or higher. If it is, the wiring is okay, and it may have been the connection. If it isn't install the jumper wire between the IAT signal circuit and the chassis ground. If now the IAT reading on the scan tool is maxed out then check for an open in the IAT ground circuit. If you get no reading at all on the scan tool, it's likely that the sensor signal is open or the 5 volt reference is missing. Check using a DVOM (digital volt ohm meter) for a 5 volt reference. If it's there, then unplug the connector at the PCM and check for continuity on the IAT signal circuit between the PCM connector and the IAT connector.

I really hope help with this (remember rated this).

SOURCE: i have five codes P2237

P2237 P2196 P2271 P0030 P0171

These are all O2 sensor trouble codes, except P0171 which is a fuel trim code,

You have a bad 02 sensor - up stream - Bank 1 Sensor 1.

Replace it, then road test. The engine computer has a 'default' fuel trim it uses when an O2 sensor fails so it can protect the catalytic converter. If this hasn't been going on too long, good chance simply replacing the O2 sensor will remedy your problem.

I have a 2007 Chevy hhr and the codes are p0102 p0113 p0171 and p0300 it won't start when I first turn the key but when I do it the second time it starts up so what could be the problem


p0102 is your Mass Air Flow device.
p0113 is "air intake temperature" sensor voltage too high.
p0171 is "engine running too lean"
p0300 is "random misfire"

You can pretty much ignore your p0113, p0171 may be caused by a bad MAF, and p0300 may be caused by your p0171.

the actual indication for your MAF is that the voltage getting to the computer from the MAF is too low. It could be a bad MAF, or bad wire between the MAF and the computer.

I replaced the engine in my 2001 ford explorer. since i have codes p0102 code p0113 code p0201 code p1504 and po775. do you have any idea what i need to do


http://www.explorerforum.com/forums/showthread.php?t=228242

This shows list of codes. You have so many faults hard to know where to start. Was new engine an EXACT match for the old one? If not, did you change ECM? Appears MAF is not connected or bad, and also #1 injector circuit is bad. Others also.

Why would installing a K & N CAI kit cause check engine light to come on


Po113 is the air temp code it was not transferred from old air cleaner po102 is a air flow code set from over oiling the new filter. the engine still will never rev over 3,000 rpms due built in rev limiter to stop over reving with no load.

Using Google-- is how you look up OBD Codes

Problems & some solutions

Type:OBD PO102

Codes DO NOT mean you replace parts

They have nothing to do with parts
UNTIL the vehicle is properly diagnosed

p0456 was likely the gas cap, evaporative emission alert.

p1273
Either the exhaust is leaking or management needs reset.

'Clear the Self Learning Data' procedure. Anytime fuel component is replace, this procedure needs to be done. (exhaust emissions as well)

1. Unplug MAF sensor
2. Start car for about 3 seconds. Turn off car. confirm P0102 code
3. re-connect MAF sensor. Clear code. START car.
4. Run car for 10 mins.

5 error cods on my 2002 Jetta GLS 1.8 Turbo Engine


P0420= Catalyst System Efficiency Below Threshold Bank 1
P0300=Random/Multiple Cylinder Misfire Detected
P0301=Cylinder 1 Misfire Detected
P0172=System Too Rich Bank 1
P2181=Cooling System Performance
you need to write these down,have someone clear the codes in the car,then go for short ride and recheck which if any code reappears.it's like domino's affect,one sensor can start a chain affect with the others.
