this car come with tree diferent engines the answer i'm going to give you is for a 1.7 engine sohc that codes means you have a leak on the evaporative system this system monitor the vapors from fuel tank this code some time might appear for filling the fuel tank with car runing i recomend you to clear code and make sure the fuel cap is not loose because there is a fuel pressure sensor in the tank and if the sensor don't read the right pressure then it will set the code

SOURCE: my 2001 honda civic reads a code P1362. what does this mean

P1362 = TDC (top dead center) sensor (1) no pulse.

Reset your car's power control module (PCM or ECU) by turning off the key and pulling the clock/backup fuse for 10 seconds then reset. Start the engine and see if the code returns. If not, it was an intermittant fault and the system is okay--but check for dirty or loose wire connector at TDC1/TDC2 sensor. If the code returns, check wiring to the sensor---if the wiring checks out, replace the sensor.

SOURCE: my 2000 honda civic engine light on code p1456

Hey I had the same code and I have a 2000 honda civic lx. My cousin works at honda and drives a '96 honda civic and he has had that code before on his car as well.

First thing he came up with was that the catalytic converter was cracked. We checked mines, and lo and behold, that's what it was.

Look under your hood, and there should be a catalytic converter with a sensor sticking out of it. It is connected to the exhaust manifold and the sensor sticks out of the heat shield. Around the sensor, look for a crack. If there's a crack, that's your problem.

I have a 2006 Honda Civic Hybrid and have had hell with it. I have also learnt much about it too.

One thing bad about the HCH2, is that the 12V battery controls the electronics, and the Hybrid battery charges the 12V battery. However the 12V battery is not charged all the time, and cannot be charged when the IMA is usually being used, and in different scenarios. (Buy a Electronic volt meter which plugs into the 12V adapter $14 Walmart))

It is possible that the 12V battery is being drained while driving and caused a voltage drop which can cause your problem. In your case, I would change the 12V battery anyway as they do not last long on Hybrids. (You may have to get Honda to trip the IMA warning lights.) In my case, changing the 12v battery helped the hybrid battery as it was the electronics reporting the charge level wrong.

Depending where you live, you will have a minimum 80,000 mile warranty on the hybrid battery.

Coud p0753 durango 1998


DTC P0753 is for the 3-4 shift solenoid in the trans.
This is an electrical code, it will set when the voltage seen by the engine controller on the solenoid's control circuit is incorrect. The solenoid pack gets a constant 12v from the trans relay and is controlled by the engine controller by switching ground.

Since you don't have a code for the TCC solenoid that shares the same relay feed and you don't have a trans relay code set we know the problem is isolated to the solenoid or it's control wire. It could be a short, broken wire, or corrosion in the control wire between the trans and engine controller, but this is almost always the solenoid itself.

This code is not not saying replace parts. They say check it out on yours a code 753 points to a 3-4 shift solenoid relay problem or wiring problem. Other thing to check could be the speed sensor module that screws into the side of the transfer case. back feeding bad info to ECM.

How do I know if the engine is running rich or running lean?


A 2002 (any car) should not be doing any of those things unless the check engine light is on. If that's the case then scan or have the car scanned for codes. If there are codes than they will give an indication as to what components to check. Otherwise the mixture of air/fuel is constantly monitored by the PCM (Power-train Control Module), which through data feedback from various sensors (such as Oxygen, Mass Air, Intake Air temp., Coolant Temp, etc . . .) constantly adjusts for the optimum air to fuel ratio by varying the injector pulse. Therefore no adjustment is necessary as this is all taken care of via a computer. Hope this helps

I have a 2003 Chevy S-10 LS with a V6 4.3L engine, and recently my check engine light went on. I used my OBD II reader and it gave me codes P0016 and P0128. Now here is my dilemma, I replace the Crankshaft...


P0016 CKP CMP Correlation case study GM 4 3 V6
The engine coolant temperature (ECT) sensor monitors the temperature of the coolant. This input is used by the powertrain control module (PCM) for engine control, and as an enabling criteria for some diagnostics.
The air flow coming into the engine is accumulated and used to determine if the vehicle has been driven within the conditions that would allow the engine coolant to heat up normally to the thermostat regulating temperature. If the coolant temperature does not increase normally or does not reach the regulating temperature of the thermostat, diagnostics that use ECT as enabling criteria, may not run when expected.
This DTC will only run once per ignition cycle within the enabling condition. If the PCM detects the calibrated amount of air flow and engine run time have been met and the ECT has not met the minimum thermostat regulating temperature, DTC P0128 sets.

Code 1529keep coming up no drveable problems


If the code you are mentioning is p1529 then it is generated by Transmission control module(TCM) to the trigger the check engine light . You have to check the code of your OBD port by using an scan tool that would give you the exact error codes from which the faulty part can be identified.

Check engine light will be triggered in case of any fault in any part in the car.Even a loose gas cap will trigger the check engine light. So having it scanned with an code reader connected to OBD port will help you to identify the exact fault.

I have a 1995 isuzu pickup it giving me error codes 15 and 34 and I've already been to 3 repair shops and can't get it fixed can you give me some help


I have the manual for my 93 rodeo and code 15 says ENGINE COOLANT TEMPERATURE SENSOR-SENSOR SIGNAL SHORTED, GROUNDED OR OUT OF RANGE. Check your coolant sensor by the water neck-it sends a signal to your dash gauge (coolant temp)
Code 34 my book has 2 symptoms- if its a 3.1 liter engine it says MAP SENSOR-SIGNAL VOLTAGE LOW-CHECK INCORRECT IDLE SPEED, VACUUM LEAKS, LOOSE AIR DUCT, MAP SENSOR CIRCUIT
If its NOT a 3.1 liter engine, then code 34 is EGR TEMPERATURE SENSOR CIRCUIT-SHORTED

Hope this helps.

2000 Daewoo Lanos engine fans run constantly


which temp sensor did you replace the one with one wire is for the gauge on the dash and the one with two wires is for the ecu the ecu controls the cooling fans so if this sensor is faulty the ecu will switch the cooling fans on because it does not know what temperature the engine is at check you have rplaced the right sensor
