Multiple Obd Codes on 1999 buick Century Custom?

In this case the customer noticed problems like .......
MIL light on dash blinks, engine lacks power, hesitates,stumbles under acceleration would like to stall at stop light.

The OBD codes P0302,P0202,P0753 are retrieved in scanning.
The Customer has already installed new spark plig wire for the #2 clyinder. Removed plug and it was wet. exchanged spark plugs 2 & 6. checked plug 2 a second time it was wet again.So the problem is similar with all this parts replacing.

On basis of this details the troubleshooting for this problem is as follows :-----

As per the details it indicated problem with injector.



Remove the plenum and check the wiring to the #2 injector. You will likely find that the injector wiring is chafed, pinched or shorted. This will cause the P0202 code and will supply too much fuel to cylinder #2 and will cause this cylinder to misfire. (P0302)

The P0753 code is a shift solenoid problem and is unrelated to the way the engine runs.


This details will help.
Thanks.

Diagnostic code P0010?

The Diagnostic code shown in car scanning.When check engine light comes up on engine,the The ecm has to be scanned.
If you are getting error code P0010.
Code P0010 refers to a fault at the Intake Camshaft Position (CMP) Actuator Solenoid Control Circuit Bank 1. This code will set if the ECM (Engine Control Module) detects that the commanded state of the driver and the actual state of the control circuit do not match for greater than 3 s.
The service procedure requires close monitoring with a scan tool. Well it may be too technical for you, but simply put, it may require replacing the CMP actuator solenoid valve if it fails the component test. If the component is found to be okay, the circuit and wirings should be checked for possible shorts or open, and also the signal performance. If all circuit tests proved normal, a replacement ECM may be recommended.
If the engine light and code is consistently present, most likely it's the actuator solenoid valve. Check it out with your trusted mechanic. 

This details will help you.

P0031 code on Dodge Dakota?

When the check engine light remains steady on car dash.There is error code stored in your car computer.In that case the car computer needs to be scanned.If you receive the code P0031 ,in that case this code is due to the heater circuit on your driver's side upstream oxygen sensor. The sensor is screwed into the exhaust manifold or possibly in the pipe just below the manifold but before the catalytic converter. Pull the connector off, turn the key on, and check the voltage across the orange and purple wires (the black wires are for the sensor signal). There should be 12 volts. If not, check the wires--sometimes they pull loose of their conduits and burn up or otherwise short out. If the voltage is good, replace the sensor.

This basic details will help.Thanks.

http://schematicsdiagram.blogspot.com/2011/12/code-p0132-on-acura-tl.html

OBD code P0191 and car runs rich?

The code P0191 means fuel rail pressure wrong.Its controlled by fuel pressure sensor.
The rail pressure sensor is bad. Thats why its running so rich. The computer is running the fuel pump way too much based on the rail pressure being wrong. Go to the local auto parts store and get the sensor replaced.This sensor is faulty causing the problem.

P1506 Idle Air Control Over Speed Error ?

The computer controls the idle speed via the idle air control valve on the intake next to the throttle body but the RPMS remain high. You need to check for vacuum leaks on any hoses to the intake or the gaskets at the intake and verify the throttle plate is not sooted and sticking open and throttle cable is not fraying and sticking. If all of these are good then a new idle air control valve needs to be installed while the negative battery cable is disconnected.So both possibilities needs to be checked, the iac valve as well as vacuum leaks.
