SOURCE: How do I fix code 13 engine speed sensor Above 1000 rpm

Clearing the codes is simple that is done by removing the fuse of the EFI from junction box 2 for 10 seconds. Make sure to remove the jumper wire and switch the key off before clearing the codes.

Here are some common Lexus vehicles 1990-1995 codes:

Code 12 and Code 13 Rpm signal circuit fault
Code 14 Igniter signal circuit fault
Code 16 ECT control signal fault
Code 21 and Code 28 Main oxygen sensor fault (for ES300; SC300 & GS300 models)
Code 22 Coolant temperature circuit fault
Code 24 Intake temperature sensor circuit fault
Code 25 and Code 26 Air fuel ratio fault (for ES300 & SC300 models)
Code 27 Sub-oxygen sensor circuit fault (for ES300 CA & GS300 models)
Code 31 Low airflow meter voltage (for ES300 and GS300 models)
Code 32 High airflow meter voltage (for ES300 model)
Code 35 Barometric pressure sensor circuit fault (for GS300 & SC300 models)
Code 41 and Code 47 Throttle position sensor circuit fault
Code 42 Vehicle speed sensor circuit fault
Code 43 Starter signal
Code 51 Switch condition signal fault (for ES300; GS300 & SC300 models)
Code 52 Code 52 and Code 55 Knock sensor circuit fault
Code 71 EGR system circuit fault (for ES300; GS300 & SC300 models)
Code 78 Fuel pump control circuit fault (for GS300 & SC300 models)

Obo scanner gave me these codes p0171, p0201, p0202, p0203, p0204, p0321 and it wont start? please help i noe what the codes mean just dont noe what to go for


I will give you what the codes mean and you can then work out what to replace.
code p0171 refers to system too lean--bank 1===causes intake / exhaust leak---AIR system---MAF/VAF sensor---fuel pressure/pump---injector/s---HO2s
code p0201 refers to injector 1--circuit malfunction===causes--- wiring--injector ---ECM
code p0202 refers to injector 2 --circuit malfunction===causes --wiring---injector--ECM
code p0203efers to injector 3 --circuit malfunction===causes---wiring--- injector --ECM
code p0204 refers to injector 4 --circuit malfunction===causes ---wiring ---injector ---ECM
code po321 refers to crank shaft position (CKP) sensor/engine speed (RPM) sensor---range / performance problem===causes---air gap---metal particle contamination---insecure sensor /rotor --wiring---CKP/RPM sensor.

I recieved Code 12 from diagnosis


For 83-86 Camry, 87 corolla, 84-87 pickups and 4-runner: Code 12 = knock sensor or circuit (distributor or circuit on Cressida, Supra, and Celica 3S-GE)

87-90 Camry, all other models 88-90: Code 12 = Rpm signal/no NE or G signal to ECU within several seconds after engine is cranked.

All models from 1991 on: Code 12 = Rpm signal No "Ne" signal to the ECM within several seconds after the engine is cranked. No "G" signal to the ECM two times in Succession when engine speed is between 500 rpm and 4000 rpm.

I have a 1992 Mitsubishi Mighty Max v6 3.0. It runs rough at high speed (not necessarily rpm) and the check engine light was on earlier this week, but is now off. Does the computer retain check engine...


Yes, the computer does retain fault codes. They can be retrived either with a scan tool or by using an analog volt meter. (Good luck finding one of those if you don't already own one.)
Volt meter method:
Find the diagnostic connector located next to the fuse lock under the left side of the dash
Connect the positive lead of the volt meter to pin 1 on the diagnostic connector.
Connect the negative lead to pin 12. Turn the ignition switch on and disclosure of the ECM memory will begin.
The ECM will output 12 volt pulses. There are long pulses and short pulses. The long pulses count as tens and the short pulses count as ones. Example: 3 long pulses and 2 short pulses means code 32.
If there are 2 or more fault codes in memory, they will be output one at a time in order of the code number from lowest to highest.
