1998 dodge dakota 3.9L engine flooding problem

Check the coolant temp sensor. Also do a throttle body cleaning ( on the truck).

1998 should be fuel injected the choke is a cod start system containing the engine coolant temp sensor. intake manifold temp sensor idle speed control motor.

TESTING
This is a test of the sensor only. A complete test of the circuit requires the DRBII scan tool, or equivalent.
Unplug the wiring harness connector from the intake manifold temperature sensor.

1. Using an input impedance volt-ohmmeter, measure across the terminals to test the resistance. The resistance should be less than 1340 ohms with the engine warm. Replace the sensor if not within specifications.
2. Test the resistance of the wire harness. Do this between the engine controller wire harness connector terminal 21 and the connector terminal. Also check between terminal 4 to the sensor connector terminal. Repair the wire harness as necessary if the resistance is greater than 1 ohm.

code 32 is related to the EGR circuit. Remove the EGR valve from the intake and check for a clogged port(s). If ports are ok, replace the EGR. Check for vacuum leaks on all hoses and connections as well as the air intake tube. Sometimes the air intake tubes crack in between the ribs on on the ends where the clamps are, causing vacuum leaks.

Check the following:- Map sensor, Air flow sensor if fitted instead of map sensor and the engine coolant temp. sensor. When did you last replace the air filter?

check the gasket for the bottom of the intake plenum
to check remove pcv valve from the valve cover plug the vent hose from the other valve cover and the hole the pcv valve was removed from with your fingers while the engine is idleing. if it builds up a vacuum, noticable by a air rush sound when you remove finger from vent/pcv grommet hole then the gasket for the plate on the bottom of the intake plenum has blown out. it is a very common problem and results in fould plugs and oil consumption problems.

check your coolant temp sensor. possible map sensor.
The MAP sensor is fitted to the front of the throttle body except on 4.7L and 8.0L engines where it is installed on the intake manifold.

1. Remove the air cleaner assembly.
2. On throttle-body mounted MAP sensors, inspect the L-shaped tube from the throttle body to the MAP for cracks, blockage, and damage. Repair as necessary.
3. Unplug the MAP sensor connector.
4. Test the MAP sensor output voltage at the MAP sensor connector between terminals "sensor ground" and "sensor signal". With ignition ON and the engine OFF , the voltage should be between 4-5 volts.
5. Check voltage across the same terminals with the engine running at idle at operating temperature. Voltage should be 1.5-2.1 volts.
6. Test MAP sensor supply voltage at sensor connector between terminals "sensor ground" and "5v supply" with the ignition ON and engine off, voltage should be 4.5-5.0 volts.
7. Test the MAP sensor ground circuit at the "sensor ground" of the MAP connector, voltage should be less than 0.2 volts. If not inspect for open harness from pin 4 of PCM harness and terminal A . If no voltage is present, proceed to the next step.
8. Turn the ignition OFF .
9. Disconnect the PCM harness from the PCM.

WARNING Testing the wiring harness with the PCM still connected can cause serious damage to the processor. ALWAYS disconnect the PCM before testing the wiring harness, unless instructed otherwise.

1. Test the MAP sensor output voltage at the PCM connector. At the PCM cavity A-27 , the voltage should be about 5.0 volts.
2. Check the voltage at PCM cavity A-17 . It should be 5.0 volts.
3. If all of the above tests pass, plug in PCM wiring harness and MAP sensor connector.
4. With the ignition in the ON position, and the engine OFF , remove the tube from the throttle body to the MAP sensor.
5. Connect a vacuum pump to the nipple on the MAP sensor, and pump the sensor to 20-27 in. Hg. Check the sensor output voltage, it should be below 1.8 volts. If not, replace the MAP sensor. If the voltage is OK, proceed to next step.
6. Relieve vacuum pressure on the sensor, then check the output voltage. The voltage should be 4-5 volts; if not, replace the MAP sensor.
7. Install the air cleaner assembly.

If you are referring to the temp sensor at the intake or the oxygen sensor at the exhaust, it may cause it to flood. There could be several causes. But usually the problem may be traced to the MAP sensor or to the injectors. If the sensors are the issue the mixture would either be rich or lean. If the flooding is that bad I would check first the injectors. Have it cleaned out first and do a physical inspection on the parts.

Assuming it has a 3.1 V-6, it could be any # of failures. Bad plug wires, ignition coils, control module (under coil packs), crankshaft position sensor, map sensor, throttle position sensor, egr valve, fuel pressure regulator, fuel injectors, engine coolant temperature sensor, vacuum leaks; have it scanned for trouble codes to help in diagnosing! If you think it is just over fueling (flooding),look at fuel pressure regulator or coolant temp sensor ( when they fail the computer thinks its always -40 F causing it to over fuel). A bad map sensor can cause the same. Hope this helps. Thanks in advance for rating me!
