CHECK ENGINE LIGHT ON MY 98 200SX 1.6 problem code P0110
Ok the check engine light on MY 98 200SX 1.6 come out this code P0110 IAT circuit sensor malfunction
I call the dealer and they need the exact sensor name
can you help my with this
Re: CHECK ENGINE LIGHT ON MY 98 200SX 1.6 problem code...
In other words give it to the dealer,you cannot read the codes because they are designed to read wrong so only a dealer can put it right.Waste of money buying these after market code readers for weekend mechanics

code p0110 refers to intake air temperature (IAT) sensor--circuit malfunction===causes--wiring ---IAT sensor---ECM
replace the sensor and reset the CPU using a code reader.
Take your car to an auto parts store and ask them to put a code reader on your car. They not only tell you what the codes are (see below) but also the most likely cause and most likely solution. Or Go Look up OBDII Codes
I personally would start by buying throttle body cleaner and having them show you where to spray it.
Code 1511: Idle Switch (Electric Control Throttle)Circuit Malfunction
Code 0070: Outside air temperature sensor -circuit malfunction
Code 0015: Engine Coolant Temperature Circuit Malfunction
Thank you for the inquiry. P0113 Intake Air Temperature Circuit High InputP0114 Intake Air Temperature Circuit P0113 - Intake Air Temperature Circuit High Input
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: 1. 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. 2. If it isn't install the jumper wire between the IAT signal circuit and the chassis ground. 3. 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.

CODE PO170 - FUEL TRIM BANK 1 MALFUNCTION. POSSIBLE CAUSES TO YOUR PROBLEM. AIR LEAKS IN THE INTAKE MANIFOLD. EXHAUST PIPES OR EXHAUST MANIFOLD. FUEL CONTROL SENSOR IS OUT OF CALIBRATION ECT IAT MAF. LOW FUEL PUMP PRESSURE FUEL FILTER CLOGGED FUEL PRESSURE REGULATOR FAULTY. ONE OR MORE INJECTORS RESTRICTED OR FUEL PRESSURE REGULATOR FAILED. HO2S ELEMENT IS CONTAMINATED DETERIORATED OR HAS FAILED.LOOK FOR VACUUM HOSE DISCONNECTED BROKEN LEAKING OR LOOSE.CHECK THE MASS AIR FLOW SENSOR SIGNAL CIRCUIT. SHOULD BE 4.8 - 5.2 VOLTS.IF SIGNAL CIRCUIT LOWER VOLTS LOOK FOR SHORT TO GROUND OR AN OPEN HIGH RESISTANCE IN CIRCUIT.IF YOU ARE 12 VOLTS FROM SIGNAL CIRCUIT PCM IS FAULTY.BEFORE SPENDING A LOT OF MONEY TAKE VECHICLE TO GARAGE OR DEALERSHIP.LET THEM TEST IAT AND MASS AIR FLOW SENSOR PARAMETER FOR THE CORRECT RANGE OR HZ USING A VARIABLE SIGNAL GENERATOR TO SEE IF IAT MAF SENSOR GOOD OR PCM FAULTY. THIS WAY YOU WONT SPEND TOO MUCH MONEY.
