Your computer relies upon the temp sender to tell it when it should switch from cold to hot mode. If it gets faulty information to begin with, nothing else in the fuel/timing management system will work properly which can cause hard starting, poor fuel mileage and overall poor running.
The results long term of not fixing the problem can range from just having an engine that never runs correctly to one with severe and expensive failures. Replace the sender!!! They are relatively inexpensive and not terribly difficult to replace.

I have Honda Accord the engine light is on and rune no more then 3500rpm


If it is a safety feature on your car, then its there to prevent you from revving above a certain RPM and blowing your engine before it can properly warm up for higher speed. Or...
It is the indication light that indicates there is a sensor not responding which will retard the performance of your car(power,fuel,heating,cooling,...) You can do a diagnostic test at Honda or you can try and trace the sensor yourself.1.check to see that none of the sensor plugs are not loose. 2. When your car does it again, remove the sensor plugs one at a time(remember to replace them if it changes the performance of the engine/car at that stage as it is not that sensor that is faulty) continue testing the sensors till the plug you pull out has no effect to the car and that is most probably the faulty sensor. Good luck

Dtc p1457,0107


P1457 HONDA - Evaporative Emissions Control System Leakage EVAP Canister Systemxicon.jpghttp://engine-codes.com/p1457_honda.htmlForum CodePossible causes- Missing Fuel cap
- Incorrect fuel filler cap used
- Fuel filler cap remains open or fails to close
- Foreign matter caught in fuel filler cap There is a Honda factory service bulletin with information on how to diagnose the P1456 on the following Honda models:
1998 Honda Accord
1999 Honda Accord
2000 Honda Accord
1998-2000 Honda Accord
symptoms- Engine Light ON (or Service Engine Soon Warning Light)
- Possible a noticeable fuel odor caused by the release of fuel vaporsP1457 HONDA Description The evaporative emission (EVAP) control system stores fuel vapor from the fuel tank in the EVAP canister temporarily to prevent it from escaping to the atmosphere and to enable it to be drawn into the engine by intake manifold vacuum and burned. In addition, the onboard refueling vapor recovery system (ORVR) stores fuel vapor generated when refueling in the EVAP canister.

The EVAP control system leak detection method improves the accuracy and frequency of the detection by determining faulty components and vapor leakage for each part. The EVAP control system (from the purge valve to the fuel tank) is divided into two parts. One is the "EVAP Canister Side" (from the EVAP two way valve to the purge valve) and the other is the "Tank Side" (from the EVAP two way valve to the fuel tank). There is 0.04 inch leak detection and 0.02 inch leak detection. If the 0.04 inch leak detection results are OK, the 0.02 inch leak detection runs. The P1457 code is detected when the EVAP system has a very small leak.

P0107 HONDA - Manifold Absolute Pressure Sensor Circuit Low Voltagexicon.jpghttp://engine-codes.com/p0107_honda.htmlForum CodePossible causes- Manifold Absolute Pressure harness is open or shorted
- Manifold Absolute Pressure sensor poor electrical circuit connector
- Faulty Manifold Absolute Pressure sensor
- Faulty Engine Control Module (ECM) When is the code detected?An excessively low voltage from the sensor is sent to ECMSymptoms- Engine Light ON (or Service Engine Soon Warning Light)
- Engine rough idle
- Engine hesitation
P0107 HONDA Description The Manifold Absolute Pressure sensor provides instantaneous manifold pressure information to the engine's Engine Control Module. The data is used to calculate air density and determine the engine's air mass flow rate, which in turn determines the required fuel metering for optimum combustion. A fuel-injected engine may alternately use a Mass Air Flow sensor to detect the intake airflow. A typical configuration employs one or the other, but seldom both.


In some vehicles the absolute pressure sensor is built into ECM.

My honda accord 1993 start the ligth abs sensor speed


Anytime the abs light is on it will disable the abs system.What you need to do is jump the 2 pin blue connector under right side of dash with a paper clip.Turn ignition switch on and count the blinks of the abs light.Most likely is a damaged or shorted abs wheel speed sensor which is most common.Here what the connector looks like that you need to jump....

12_19_2011_2_21_55_am.jpg

If your ABS light tunr on, is telling you there is an issue with the abs pump itself.It could be possibly failing or just air bound but theses are known to leak .You need to check the pump next.

Hope this helps; also keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using Fixya, and have a nice day

I sent my honda accord 1993 to honda dealer/repairer to get check why check engine ligths come ON.they said faulty collant sensor/is this serious problem?and why if the check engine ligths comes on,my car...


a bad coolant sensor not a serious problem that can cause engine damage. but it will make it run real bad ,use alot of fuel ,hard start,ruin your cat converter,etc.they arent that expensive and are easy to put in.
think of your coolant sensor like your choke.it tells the computer how warm/cold the engine is and then compuer when it thinks cold gives more gas or hot and gives less gas.if comuter dont know temp of engine it has to guess and they are always wrong.
coolant sensor bad computer has no way of knowing engine temp

1993 honda accord engine service light is on and Shift drive D4


If the drive light flashes there COULD be a trans problem. The Ck Engine light and the D4 light are on for the same reason. Take it to a qualified repair shop to have it checked out. Find a shop that regularly works on HONDA and not some chain store operation.

Failed emission NOx on a 93 Honda accord ex its papes the 25/25 test but not the 50/50 test. what is wrong how do I fix this? check engine light stays on?


The only thing I can think of checking would be the EGR valve, a faulty cat converter or faulty o2 sensor. Converter shouldn't set off check engine light though unless it is clogged causing too much back pressure, most likely EGR Valve.
