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

I just replaced the wheel bearing on my 2009 Malibu. The ABS and ESC lights won't go out. I returned the bearing thinking the electronic sending unit was bad. Just put in second bearing and ABS and ESC...


Get in there with a scan tool that can read data and codes. Pull the code. Look at the ABS data related to that code. That's the first step in diagnosing the problem correctly. The code doesn't tell you what part to replace; it gives a direction to go with diagnosis. Otherwise you're just shooting in the dark and wasting money guessing at it. If you verified for sure that you've got a bad wheel speed sensor and replaced the correct one, newer GM vehicles won't clear out an ABS light until it sees the vehicle move, and the sensor starts reading speed correctly. Usually it needs to see speeds above 25 miles an hour before the lights will clear out- IF you've correctly diagnosed and replaced a bad wheel speed sensor.

Abs on vr commodore light stays on solutions


Error logs are a great thing. They will help you find intermittent problems and start you off in a general direction of where a problem could be. There is a great level of detail on the justcommodores site on checking error codes logged by the engine management system, but this does not detail anything about the abs system. The abs warning light is not as common as the check engine warning light. Reading through the posts, I haven't found any detail on checking error codes logged by the abs system.

So here it is. For those of you familiar with checking the engine error codes, this procedure is so simple its not funny.

Basically, to check the engine error log, you bridge the 5th (ground) and 6th pins in the ODB connector under the steering wheel.

To check the ABS error log, using the same trusty calibrated paper clip, you simply bridge pins 5 and 12 of the connector.

To find pins 5 and 12, start at the top left hand corner. That is pin one. Going to the right, you count pin 2,3,4 etc. Once you get to the end, jump back to the start of the bottom left level of pins and keep counting. Pin 5 is about halfway along the top row, pin 12 is a little left of the middle in the bottom row.

Reading the error codes is the same procedure (counting the flashes), except now, the ABS light flashes (as opposed to the engine light when checking the engine codes).

The ABS log also uses code 12 firstly, with any errors logged shown after that. If no errors are logged, the 12 will flash again.

Error codes for the ABS error log (VR/VS) are as follows:

12 Diagnostic system operational
21 Right hand front wheel speed sensor fault
23 Right hand front wheel speed sensor continuity fault
25 Left hand front wheel speed sensor fault
27 Left hand front wheel speed sensor continuity fault
28 Wheel speed sensor frequency error
31 Right hand rear wheel speed sensor fault
33 Right hand rear wheel speed sensor continuity fault
35 Left hand rear wheel speed sensor fault
37 Left hand rear wheel speed sensor continuity fault
41 Right hand front inlet solenoid valve circuit fault
42 Right hand front outlet solenoid valve circuit fault
45 Left hand front inlet solenoid valve circuit fault
46 Left hand front outlet solenoid valve circuit fault
55 Rear inlet solenoid valve circuit fault
56 Rear outlet solenoid valve circuit fault
61 Pump motor relay circuit fault
63 Valve relay circuit fault
71 ABS control module internal fault

The above guide has been verified on a VR/VS. Checking the error log on all models prior to VR/VS is the same for the engine log, and I would assume that the same can be said for the ABS log, would be happy if someone could verify this for me.

ABS and OD lights are on and transmission is kicking out could this all be related


Could be a fuse or a wheel speed sensor; next, check the tone rings on the axle shafts and see if they are not broken.

I quote this information from Jeep lover's...

The amber ABS warning lamp is located in the instrument cluster. It is used to inform the driver that the antilock function has been turned off due to a system malfunction. The warning lamp is controlled by the CAB and/or the main relay through an in-harness diode. The CAB controls the lamp by directly grounding the circuit. The main relay grounds the lamp circuit when it is de-energized.
The re BRAKE warning lamp is located in the instrument cluster. It can be activated by application of the parking brake or leak in the front or rear wheel brake hydraulic circuit.
The antilock brake controller (CAB) is a microprocessor-base device that monitors wheel speeds and controls the anttlock function.
The primary functions of the CAB are:
- monitor wheel speeds
- detect wheel locking tendencies
- control fluid pressure modulation to the brakes during antilock stop operation
- monitor the system for proper operation
- provide communication to the DRB while in diagnostic mode
- store diagnostic information in non-volatile memory
The CAB continuously monitors the speed of each wheel. When a wheel locking tendency is detected, the CAB will command the appropriate valve to modulate brake fluid pressure in its hydraulic unit. Brake pedal position is maintained during an antilock stop by being a closed system with the use of 3 accumulators. The CAB continues to control pressure in individual hydraulic circuits until a wheel locking tendency is no longer present. The CAB turns on the pump/motor during an antilock stop.
The antilock brake system is constantly monitored by the CAB for proper operation. If the CAB detects a system malfunction, it can disable the antilock system and turn on the antilock warning lamp. If the antilock function is disabled, the system will revert to standard base brake system operation.
The CAB inputs include the following:
- four wheel speed sensors
- stop lamp switch
- ignition switch
- main relay voltage
- pump/motor relay output
- diagnostic communication ISO/K
- G switch (acceleration switch)
The ABS main relay is located in the power distribution center (PDC). The main relay has two functions. First, when the relay is energized, it supplies power to the valve/solenoids in the valve block assembly and the pump/motor relay coil. Second, when the relay is de-energized, it supplies a ground to turn on the ABS warning lamp. The main relay is controlled by the CAB. The CAB energizes the main relay when it receives an ignition input signal.
The ABS pump/motor relay supplies power to the pump/motor. It is also located in the PDC. The relay coil is powered by the main relay and the coil ground is controlled by the CAB. The pump/motor relay is a special five-terminal relay and should not be replaced with a standard relay.
One wheel speed sensor (WSS) is located at each wheel and sends a small AC signal to the control module (CAB). This voltage is generated by magnetic induction when a toothed sensor ring (tone wheel) passes by a stationary magnetic sensor (wheel speed sensor). The CAB converts the AC signals into digital signals for each wheel.
The front wheel speed sensor air gap is NOT adjustable. The correct front wheel speed sensor air gap is from 0.40mm to 1.3mm. Preferred rear sensor air gap for drum brake systems is 1.1mm. Acceptable air gap range is 0.92mm to 1.275mm. For rear disc brake systems, the preferred rear sensor air gap is 1.2mm. Acceptable air gap range is 0.95mm to 1.45mm. All wheel speed sensors have a resistance between 900 and 1300 ohms.
Correct antilock system operation is dependent on tone wheel speed signals from the wheel speed sensors. The vehicle's wheels and tires should all be inflated to the recommended pressures for optimum system operation. Variations in wheel and tire size or significant variations in inflation pressure can produce inaccurate wheel speed signals; however, the system will continue to function when using the mini-spare. When driven over rough road surfaces, the rear wheel speed sensor signals may be erratic and cause a false trouble code (drum brakes only).
Diagnostic trouble codes are retained in memory until erased using the DRB, or automatically erased after 50 key cycles.
Ensure you are using a DRBIII scan tool properly connected to the data link connector located under the dash to the right of the steering column.
Select "Anti-lock Brakes" the "Teves ABS". Turn the ignition on.
Read and record all ABS diagnostic trouble codes. If the "Valve Power Feed Circuit" trouble code is present, it must be repaired before prior to addressing any other DTCs.
If there are no trouble codes present, select "Inputs/Outputs" and read the brake switch input as you press and release the brake pedal. If the display does not match the state of the pedal, check for 8 volts at the brake lamp switch output circuit. If the voltage is not present, repair the open brake lamp switch output circuit. If the voltage is present, replace the CAB.
If the display does match the state of the pedal, read the "G-Switch" status, with the vehicle on a level surface, both switches should read "CLOSED". If the status is not correct, make sure the G-Switch is properly mounted and connected (under the driver's side rear seat). If it looks correct, you'll have to check for voltage to the G-Switch.

Hope helps.
