After replacing sensors and cat, I continue to get the check engine light after it's been cleared?


the check engine light comes on when a sensor is giving problem, when you clear the codes and the light came back did you check to see which code came back? Because right there would be the problem.

My nissan 95 truck won't start. the battery is ok. once it wouldn't start and i put it in neutral then back to park and it started right up. where is the neutral safety switch located? I heard...


I think your reverse to park trick was a fluke,, I assume it turns over but since it is a 1995 you dont have a OBD 2 in the vehicle.
How to pull ECU error codes for 87-95 Pathfinders and Hardbody pickups:


The ECU is under your passenger's side seat. You can gain access to it by simply sliding the seat all the way forward and removing the plastic cover from the ECU. You can also remove the seat if you want, it makes access a little easier.

The VG30i ECU's have a tiny toggle switch on the side of the ECU with a small snap-in switch cover that must be utilized to select the diagnostic mode of the ECU. The 4-cylinder ECU and the VG30E ECU has a slotted switch that turns 1/4 or 1/2 turn clockwise and counterclockwise to do the same task. Some early 4-cyl HB ECU's have the switch as well. In any case it will have one or the other.

For 4-cylinder:
1. Turn the ignition switch on, but do not start the engine. All of the lights in the dash should be on.
2. Turn the 'diagnostic mode selector' screw on the ECU fully clockwise. The check engine light will go out. Wait 5 seconds, then turn the screw fully counter clockwise.
3. The check engine light will then begin to flash the trouble code. (number of long flashes is the 1st digit, number of short flashes is the 2nd digit)
4. To clear all stored codes and turn the check engine light off, turn the screw fully clockwise while it is in diagnostic mode. Wait 5 seconds, then turn the screw fully counter clockwise.
5. To keep the codes stored, simply turn the key off as the check engine
light is flashing and the ECU will keep all stored codes and the check engine light will remain on.

For V6:
1. Turn the ignition switch on, but do not start the engine. All of the lights in the dash should be on.
2. For VG30i: There is a little plastic tab you pull off of the side of the ECU(facing the door). A small toggle switch is behind it with 2 positions, "ON" and "DIAGNOSTICS". Using a small screwdriver or tool, move it to the diagnostics position. The red and green LED's on top of the ECU will blink simultaneously. One time, pause, then 2 times, three times, pause...so on for each mode, 1 through 5. Mode 3 is the most commonly used mode and will yield the ECU trouble codes you need to figure out what's going on with your engine.
For VG30E with slotted switch: Turn the 'diagnostic mode selector' screw on the ECU fully clockwise. The check engine light will go out. Wait 5 seconds, then turn the screw fully counter clockwise.
3. After it blinks both LED's 3 times move the toggle switch back to the on position. After about five seconds it will start to output out the diagnostic codes as with the 4-cylinder ECU. Note each code as it is displayed, the red LED flashing once for 10's, and the green LED flashing once for 1's. Meaning: One red flash and two green flashes means code 12.
4. To clear the ECU of any trouble codes, move the switch to the "DIAGNOSTICS" position then back to the "ON" position and turn off the key.

ECU Diagnostic Mode Procedures
Mode I - Exhaust Oxygen Sensor Monitor
-----------------------------------------------------------------------
Use Mode I to determine if the Oxygen Sensor is functioning properly.

Warm the engine to normal temperature.
Run the engine above 2000 RPM under no load while looking at the ECU.
Make sure the GREEN LED goes on and off more than five times during ten seconds at 2000 RPM.
If the number of flashes are not more than five, replace the oxygen sensor. If the LED does not flash, check the sensor's circuit.


Mode II - Mixture Ratio Control Monitor
-----------------------------------------------------------------------
Use Mode II to determine if the air/fuel mixture is cycling correctly.

Warm the engine to normal operating temperature.
Turn the dial on the ECU fully clockwise (or if you have a switch, turn it on).
After the LED flashes twice, turn the dial fully counter clockwise (or turn the switch off).
Run the engine above 2000 RPM under no load while looking at the ECU.
If the RED LED blinks simultaneously with the GREEN LED, the air/fuel mixture is cycling properly.
If the RED LED stays off, the mixture is more than 5% rich.
If the RED LED stays on, the mixture is more than 5% lean.
If the RED LED stays on or off above 2000 RPM, complete the diagnostics before beginning repairs.


Mode III - Stored Fault Code Reporting
-----------------------------------------------------------------------
Use Mode III to retrieve all stored trouble codes in memory.
Use the above posted procedures.


Mode IV - Switch Operation Monitor
-----------------------------------------------------------------------
Use Mode IV to determine if the Throttle Position Sensor (TPS), Starter circuit and/or Vehicle Speed Sensor (VSS) are in proper working order.

Turn the ignition switch on, but do not start the engine.
Turn the dial on the ECU fully clockwise. After the LED flashes 4 times, turn the dial fully counter clockwise.
Make sure the RED LED is turned off.
Make sure the RED LED turns on when depressing the gas pedal. If not, check or replace the Throttle Position Sensor.
Make sure the RED LED turns on when turning the ignition key the START position. If not, check or replace the starter.
Drive the vehicle with the ECU unbolted and within view. Make sure the GREEN LED turns on when speed is 12 MPH or more. If not, check or replace the Vehicle Speed Sensor.


Mode V - Real Time Diagnostic Function
-----------------------------------------------------------------------

Use Mode V to determine if the Crankshaft Position Sensor (CPS), Mass Air Flow Sensor (MAFS) and/or Ignition signal are working properly.

Start engine.
Turn the dial on the ECU fully clockwise.
After the LED flashes 5 times, turn the dial fully counter clockwise.
Make sure LEDs do not flash for 5 minutes when racing or idling the engine.
If it flashes, count the number of flashes, turn engine off, and see the following 3 paragraphs. Perform real-time diagnosis inspection and repair or replace malfunctioning part if present.
if LEDs do not flash for 5 minutes, turn engine off.

If the RED LED flashes 3 times for 1.5 seconds, check the Crankshaft Position Sensor. Check the harness continuity at CPS when the engine is stopped. Inspect the harness for dust and clean if necessary. Check the pin terminal at ECU for bends and remove them as necessary. Reconnect harness and recheck continuity. During real-time diagnosis, tap the harness connector or component and check if trouble code is displayed. If so, replace terminal.

If the GREEN LED flashes twice-3 times for 0.5 seconds, check Mass Air Flow Sensor. Check the harness continuity at MAFS when the engine is stopped. Inspect the harness for dust and clean if necessary. Check the pin terminal at ECU for bends and remove them as necessary. Reconnect harness and recheck continuity. During real-time diagnosis, tap the harness connector or component and check if trouble code is displayed. If so, replace terminal.

If the GREEN LED flashes 4 times for 0.2 seconds 3 times, check the ignition signal. Check the harness continuity when the engine is stopped. Inspect the harness for dust and clean if necessary. Check the pin terminal at ECU for bends and remove them as necessary. Reconnect harness and recheck continuity. During real-time diagnosis, tap the harness connector or component and check if trouble code is displayed. If so, replace terminal.

Hope this helps...

1996 dodge caravan 2.4 liter 4 cylinders .Engine service light comes on for a period of 2 to 3 months then goes off .Prior to this the engine light stayed on continuously ,until the oxygen sensor connected...


There is some sort of diagnostic code stored in either the ECM(engine computer) or TCM(transmission computer).There are many sensors and solenoids and other data parameters that can cause a codes to set other than just the oxygen sensors.You will need to have the code(s) pulled to know where to start.

My check engine light just came on. The diagnostics say that I need a P0155 sensor. I have a 2003 Toyota Highlander with a 3.0 engine.


P0155 indicates the heated O2 sensor is malfunctioning-If your oxygen sensor has 4 wires on it, it only means it has a heater circuit on it and it is used by the sensor to make the sensor more responsive to the demands of the engine. The heater usually is a separate circuit of wires that are use to supply power and ground to the heater element inside the sensor. To fix this code is normally done by replacing the sensor if they are more than 50,000 miles old (for older engines) and 100,000 miles for newer engines. If the signal wire does not switch, check the continuity of the signal wire from the sensor to your computer.

P1447 and knock sensor code both knock sensor and evap purge valve are in perfect working order and vacuum hose are correct routing and no crack but engine light is still on please help cant pass...


If your map sensor is bad, it will also cause p1447 to illuminate.
You can check the air passage continuity on the map sensor/solenoid valve.
Provide the switch with 12 volts, please note which pin is positive and negative.

Check air passage continuity between A-B, A-C. My manual shows that if there is no continuity between A-B but there is between A-C then your map sensor/solenoid valve is bad and should be replaced.
It is listed as a cause for the p1447 light.
I hope this helps

I have a 03 FXDWG and the rear brake light stays on all the time. The front and back brakes are free and do not seem the be bound up. There is a sensor by the rear brake reservoir that has wires running to...


Yep, the pressure sensing switch(sensor) is probably stuck. Pull one of the wires off, the light should go out. Remove the other wire and use a DVOM set to "continuity"or a self powered test light. Touch it across the 2 wire terminals on the switch and see if the meter shows continuity or the light come on. Step on the brake, it should change.I believe the switch is part of the brake line, so the whole thing has to be replaced. If you have air in the brake lines, I have seen engine heat expand the air enough to turn on the brake light, but not apply the brakes.
