Hi,

The engine runs better when the MAF is unplugged because the PCM covers for the loss of signal with backup strategy. The IAT indication high in and MAF low input actually mean lack of signal. It sound like either you have a wiring and or connector concern and if your sure the connector and wiring are OK and the MAF you replace was good then you have a problem with the PCM.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

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.

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.

What is code p0113


P0113 IAT (intake air temperature)sensor 1 circuit high.When you get a circuit sensor high it basically means the sensor is open internal, or its disconnected, broken harness,signal shorted to voltage, The ECM sees a 4.6 with key on engine running.

Hello, I had my car hooked up to a computer today and the codes P102, P0113, and P111 came up. The engine misses when driving down the road, and the car frequently dies when turning corners and idling. ...


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). Possible causes are Open circuit in harness, Sensor signal short to power, Damaged Sensor, Improper harness connection, Damaged PCM

P0102 Mas 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. Possible causes are MAF sensor disconnected, MAF circuit open to PCM, VPWRopen to MAFsensor, PWR GND open to MAF sensor, MAF RTN cirbuit open to PCM, MAF circuit shorted to GND, Intake air leak (near MAF sensor), A closed throttle indication, Damaged MAF sensor, Damaged PCM.

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).

My 2000 ford focus has codes p0102 and p0113 whats that and what could it be?


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.
