    need help with 1999 neon code p1490

  • Anonymous Nov 26, 2008

    I have a 96 neon that displays the error code 35 which indicates a problem with the low speed idle circuit. The only physical symptom that I have noticed is a rough idle when the defroster is turned on.

If you are talking about the cooling fan relay for the radiator there is no low speed and high speed relay. There is only one relay and it is behind the grill revitted to the bumper rail. It is doesnt look like you typical relay.

This may be a late posting, however for future neon fan relay searchers just look under the battery tray. Remove the battery and battery tray then it will be located on the same wall as the two bolts that hold the bottom of the battery tray. Just before the radiator. Its tough to catch but u can access it from the bottom of the vehicle also. its much simpler just to remove the battery tray. Hope this helps.

Sounds like low speed coil in the Blower Fan resistor block has failed. The Blower Fan Resistor Block is usually located in the air ducting adjacent to the Blower Fan. The Resistor Block consists of 3 or 4 coils of special resistance wire attached to terminals which connect to the wiring that comes from the fan switch and then to the Blower Fan. The block is on the output side of the fan unit so that the airflow from the fan past the coils inside the duct assists in preventing them from overheating and burning out.
Access to the Resistor Block is from under the dash. To replace, remove the multi-pin connector and then undo the screws holding in the block. Check air duct for leaves and dirt which may have caused the coils to fail. .Replacement is the reverse procedure

If the oil smells like gas , pull the dip stick an put a lighter to it ! If it catches fire there is gas in the oil ! you don't won't to drive the car it could explode ! .
P1391 is for camshaft position sensor and crankshaft position sensor. the code is for either sensor or both

With all these codes present , without looking under the hood , I would think you have a wiring harness problem ! I have seen critters make nests in the engine compartment , they like to chew wiring ! Have seen air filter boxes full of dog food . Good luck your going to need it !

What is dtc p1490 and how do I fix it


P1490 means Low Speed Fan Relay Circuit Conditions
You need to take the car to a shop as this condition requires more diagnosing of electric circuits.

P1490 Low Speed Fan CTRL Relay Circuit. You need to check and make sure the cooling fan is coming on when the engine reaches operating temperature and when you turn the A/C on. If not, replace the Low Speed Fan relay.

Have two codes 1490 and 1489 what are they and how do i fix them


It's most likely low speed fan control relay circuit trouble.
There are separate relays and control circuits for high and low speed for the fans. This way if one messes up the other one should still work. Relays are in relay/fuse block under the hood. There is a diagram under the relay box cover that shows the function of each relay. The relays just plug in.

1489 = High Speed Fan CTRL Relay Circuit - An open or shorted condition detected in the control
circuit of the high speed radiator fan control relay.

1490 = Low Speed Fan CTRL Relay Circuit - An open or shorted condition detected in control circuit of
the low speed radiator fan control relay.

Either the relays are gone or the connector isn't plugged in, probably the connector if both the low and high circuit is out.

My check engine light came on after i put freon in the car for the air condition. my friend has a computer that we hooked up to the car to find out what the problem was and this code came up P1490, what...


When you get that code it means that the computer isn't detecting the relay kicking in and starting the cooling fan.
In most cases replacing the relay for the fan will cure that problem and you can erase the code with scanner once the problem is repaired
P1490 Low Speed Fan CTRL Relay Circuit - you need to check and make sure the cooling fan is coming on when it suppose to.

DTC P1495 - Leak Detection Pump Solenoid Circuit

WHEN MONITORED: Immediately after a cold start, with battery/ambient temperature between 4.4 °C (40 °F) . F and 32 °C (90 °F) . Coolant temperature within -12 °C (10 °F) of battery/ambient

SET CONDITION: The state of the solenoid circuit does not match the PCM's desired state.

POSSIBLE CAUSES:
* Wiring Harness Intermittent
* Leak Detection Pump
* Fused Ignition Switch Output
* LDP Solenoid Control Circuit Shorted To Ground
* LDP Solenoid Control Circuit Open
* PCM

Leak Detection Pump System
The evaporative emission system is designed to prevent the escape of fuel vapors from the fuel system. Leaks in the system, even small ones, can allow fuel vapors to escape into the atmosphere. Government regulations require on-board testing to make sure that the evaporative (EVAP) system is functioning properly. The leak detection system tests for EVAP system leaks and blockage. It also performs self-diagnostics. During self-diagnostics, the Powertrain Control Module (PCM) first checks the Leak Detection Pump (LDP) for electrical and mechanical faults. If the first checks pass, the PCM then uses the LDP to seal the vent valve and pump air into the system to pressurize it. If a leak is present, the PCM will continue pumping the LDP to replace the air that leaks out. The PCM determines the size of the leak based on how fast/long it must pump the LDP as it tries to maintain pressure in the system.

SYMPTOM: P1490-LOW SPEED FAN CONTROL RELAY CIRCUIT
WHEN MONITORED: With the ignition ON. Battery voltage greater than 10 volts .

SET CONDITION: An open or shorted circuit is detected in the radiator fan relay control circuit.

POSSIBLE CAUSES:
* Low Speed Radiator Fan Relay Intermittent Operation
* Intermittent Condition
* Fused Ignition Switch Output Circuit
* Low Speed Radiator Fan Relay Resistance
* Low Speed Radiator Fan Relay Control Circuit Open
* Low Speed Radiator Fan Relay Control Circuit Short To Ground
* PCM


Notes
The Transmission/Transaxle Controller monitors the malfunction of sensors and actuators relating to Transmission/Transaxle Control. If any malfunction is detected, they inform the PCM by sending a signal - By illuminating the MIL and by setting the P0700 code.

P0700 means that a code has been set in the Transmission/Transaxle Controller. If P0700 is present, check for Transmission/Transaxle codes.

Hope helps (remember comment and rated this).
