    what code reader where you using to get that code?

    i did a little research myself, and these may be of help to you:




    P1569

    Mazda

    Intake Manifold Runner Control Circuit Low (see P0661)
    or

    vtcs could mean vacuum temp control sensor could be bad

What should I check with 3 codes P0051 , P0300, P1512 .its only car I have and I need expert advice what's smartest cheapest thing to do?


the following link is courtesy of obd codes .com the p0300 misfire code can be from the other to codes P0051 - Oxygen (A/F) Sensor Heater Control Circuit Low (Bank 2 Sensor 1) OBD-II Trouble Code Technical Description Generic: Oxygen (A/F) Sensor Heater Control Circuit Low (Bank 2 Sensor 1) Nissan: Heated oxygen sensor (HO2S) 1 Bank 2 - heater voltage low What does that mean? A P0051 DTC (diagnostic trouble code) refers to the O2 sensor (oxygen sensor) located on Bank 2 in front of the catalytic converter. There is also an oxygen sensor behind the converter which is Sensor #2. This O2 sensor #1 may also be refered to as an air/fuel ratio sensor since on some vehicles it is. It detects the amount of oxygen in the exhaust gas compared to the outside air and then vehicle's computer adjusts the air/fuel ratio going into the engine. The sensor is less effective when the exhaust gas temperature is low, so it includes a heater which is activated to help get better readings from the A/F O2 sensor. Essentially this P0051 code means that the resistance of the heater circuit is lower than normal. In most cases, that resistance level must fall below 0.8 A to trigger the DTC code. Note, this code is very similar in nature to P0031, P0032, and P0052 Potential Symptoms Most likely you'll not notice any symptoms other than the MIL (malfunction indicator lamp, a.k.a. the check engine light) will illuminate. Causes A P0051 DTC trouble code may be caused by one or more of the following: A short in the heater circuit in the sensor A failed O2 sensor heater Wiring/connectors broken/frayed leading to sensor and/or relay Failed PCM/ECM Possible Solutions To fix a P0051 DTC code, you'll need to do a proper diagnosis. To do that, you'll want to inspect the wiring and connectors leading to the sensor. Also if equipped with a heater relay and fuse, you'll want to check those as well. Use a digital volt ohm meter to: check for 12 volts at the heater circuit feed (hint: unplug the sensor and check at the wiring connector to do this measurement) check the ground circuit for continuity measure the resistance of the heater circuit (done on the sensor itself) measure the resistance and voltage of the wiring Refer to a service manual for the correct specifications (volts, ohms) for your vehicle. On some Toyota vehicles this code is triggered when the resistance of the heater circuit is below 0.8 A. With that said, a common fix for this DTC is to replace the air/fuel (O2 oxygen) sensor #1 on bank 2 (the side of the engine that doesn't contain cylinder #1). Please keep in mind that OEM (original equipment) replacement sensors are recommended (from the dealer). Aftermarket sensors can be less reliable and of poorer quality (not always, but more often). There's also a chance that replacement parts for the P0051 code may also fall under a federal emissions warranty (check with your dealer to see if it's covered).

Copyright OBD-Codes.com OBD Codes Your OBD-II Trouble Codes Repair Site Home Trouble Codes FAQs Forums Store P0300 Diagnostic Code - Random Misfire Technical Description Random/Multiple Cylinder Misfire Detected What does that mean? Basically this means that the the car's computer has detected that not all of the engine's cylinders are firing properly. A P0300 diagnostic code indicates a random or multiple misfire. If the last digit is a number other than zero, it corresponds to the cylinder number that is misfiring. A P0302 code, for example, would tell you cylinder number two is misfiring. Unfortunately, a P0300 doesn't tell you specifically which cylinder(s) is/are mis-firing, nor why. Symptoms Symptoms may include: the engine may be harder to start the engine may stumble / stumble, and/or hesitate other symptoms may also be present Causes A code P0300 may mean that one or more of the following has happened: Faulty spark plugs or wires Faulty coil (pack) Faulty oxygen sensor(s) Faulty fuel injector(s) Burned exhaust valve Faulty catalytic converter(s) Stuck/blocked/leaking EGR valve / passages Faulty camshaft position sensor Defective computer Possible Solutions If there are no symptoms, the simplest thing to do is to reset the code and see if it comes back. If there are symptoms such as the engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter needs to be replaced. I've also heard in other cases the problems were faulty fuel injectors. Random misfires that jump around from one cylinder to another (read: P030x codes) also will set a P0300 code. The underlying cause is often a lean fuel condition, which may be due to a vacuum leak in the intake manifold or unmetered air getting past the airflow sensor, or an EGR valve that is stuck open. It is helpful to have access to a factory service manual and an advanced scan tool to properly diagnose a random misfire DTC.

This video is intended for auto repair professionals but could be helpful to DIYers. It shows use of an advanced OBD-II scan tool during diagnostic steps:

you could try to remove the EEC and inspect the pc board for leaking capacitors i hope it helps

HELP PLEASE


Code 452 is for a low voltage signal coming from the pressure sensor. The computer sends voltage to the sensor and expects a return voltage within a certain range.
If you have replaced the pressures sensor and the problem continues, it may be in the wiring between the computer and the sensor.

P1512 of my 00 MPV, what is the solution?


DTC P1512 - VARIABLE TUMBLE CONTROL SYSTEM (VTCS), STUCK CLOSED
The air intake hose that goes from the air filter/mass airflow sensor to the throttle body they are common to crack. This air leak can cause a lean condition if that checks out ok then the issue is usually a faulty mass air flow sensor .This would need to be checked next.

Usually the actuator valve is stuck closed. These are the most common causes of the P1512 and possible causes are:
* ECT sensor malfunction.
* MAF sensor malfunction.
* IAT sensor malfunction.
* EGR boost sensor malfunction
* TP sensor malfunction.
* CKP sensor malfunction
* VTCS solenoid valve malfunction.
* VTCS shutter valve stuck closed.
* VTCS shutter valve actuator stuck closed.
* Short circuit between PCM and VCTS solenoid valve.
* PCM malfunction.

I would start with the mass air flow sensor this can cause all these issues. Then the cat. This would be the next step.

I hope this helped (remember to rate and comment this answer).

Code po157 what does it mean and how do i fix it?


P0157 Oxygen Sensor Circuit Low Voltage (Bank 2 Sensor 2)

I would try replacing the Oxygen sensor, then clear the code.

The O2 sensor would be the after the catalytic converter ( sensor 2) on the exhaust pipe of the number 2 cylinder uses ( bank 2).

2000 lincoln ls i got a trouble code p1633 (KAM)voltage to low


P1633 means KAM (Keep Alive Memory ) Voltage too low. the KAM is caused by low battery voltage and you replace the battery.When you replace the battery the KAM loses Memory and the problems resulting in what you are experiencing now.When replacing a new battery, reconnect the Positive cable first.And use a trickle battery charger set low to the cables before disconnectng the battery . this will keep the voltage to the ECM powered with enough voltage. All you can do now is make the computer relearn the way it should run. Disconnect the negative cable from the battery, wait a while 20 seconds or so. then reconnect the cable. I do not know if this is a temporary fix or not but it should re-program the computer.
