P 1193 air inlet temp to high

Intake air flow meter and air intake temp sensor give ECU information; then coolant temp sensor has big influence on fuel mix, throttle position sender tells ECU what driver wants, then O2 sensor(s) do fine trim to fuel mix.

Emission system -- Inlet Air Temp. Circuit High
voltage. The sensor is detecting too hi a voltage at the throttle body - could indicate plugged air filter, not enough air getting to engine OR the sensor has gone bad.

Code 1193 is for the intake air temp sensor telling the computer the air temp is very high when it is not. The temp sensor and circuit would need to be checked with a scanner to verify the problem.

P1684 - the battery has been disconnected within the last 50 starts , pretty much harmless, maybe it's time for new battery or check battery terminal connection.
P0123- throttle position sensor high input - probably broken sensor or wire, mechanic has to check it, engine has rough/high idle
P0118 - Engine Coolant Temperature Circuit High Input
P1193. Inlet Air Temp. Circuit High.
If you have all of those at once, it is not likely that 3 different sensors go bad at the same time. Check harness and connections to ECM,

P1193 DODGE/CHYRSLER - HO2S (O2 SENSOR #1) Insufficient Switching Bank 2 O2 Sensor #1

P1193 - INLET AIR TEMP SENSOR VOLTAGE HIGH

WHEN MONITORED
With the ignition ON and battery voltage greater than 10.4 volts .

SET CONDITION
The inlet air temperature sensor circuit voltage at the PCM goes above 4.9 volts .

POSSIBLE CAUSES

• Intermittent condition
• IAT sensor signal circuit shorted to battery voltage
• IAT sensor internal failure
• IAT sensor signal circuit open
• Sensor ground circuit open

Hope helps.

This code is for the intake air temp sensor, it is either on the air cleaner box or in the hose that connects box to engine.Many times it is just unpllugged because someone changed air filter.Since this is a voltage error code if is no unplugged then it is most likely bad.

Usually means the starter has open windings or a short. Remove the starter and take to parts store for testing. Please let me know if you have more questions.

1. Remove or disconnect the following:
   
   Negative battery cable Inlet hose from the intake manifold and reposition the air cleaner box, on high output engines only Starter electrical connectors Starter-to-engine bolts Starter

To install:

1. Install or connect the following:
   
   Starter and torque bolts to 40 ft. lbs. (54 Nm) Starter electrical connectors Intake manifold inlet hose on high output engines Negative battery cable

bit to do to replace the oil pump
yours is a second gen
its repair manual would help

Second generation (1999-2005)
have 2003 neon and was wondering where the oil pump is located

The code is for the inlet air temp sensor voltage high. Check and make sure the sensor is plugged in, It will be on the intake manifold or the hose to the intake manifold. If it is plugged in you need to check that all the wires are in good condition. If they all look good there are alot of possiblities for the cuase of this code. Most likely cuase is the inlet air temp sensor. But it could still be in the wiring or in the pcm (engine computer)
