1774 and 1775


There is probably no need to contact the BAR though you always have the right reserved. Trouble Code P1774 indicates your Mini's rear wheel speed sensor lost its signal, and trouble code P1775 indicates the right rear wheel speed sensor lost its signal as well. Both more than likely triggered during the dynamometer portion of the smog check inspection; while the front wheels are turning and the rear wheels are stationary. During this time, as far as the ABS system knows, the rear wheel sensors have lost their signals.
After a computer reset and driving your Mini Cooper for a few miles everything should return to normal, as apparently they have; and you've passed the smog check. Should the check engine light return in the near future for the same trouble codes P1774 and P1775 we'd recommend inspecting the rear wheel speed sensors for possible debris build-up. Since these trouble codes where triggered during the smog check and smog check machine failure we can assume the trouble codes were temporary and not related to any physical problem with your Mini Cooper.

The rear axle sensor will not cause this. You may have a failing ****** here.

Subaru 97 speed sensor trouble code p0500 not passing admissions.. what part to I buy and where is the sensor located?


There are actually two Vehicle Speed Sensors (VSS). I'm going to assume you have a 2.5 liter engine and an automatic transmission.

The Vehicle Speed Sensor 1 (output shaft rotation sensor) is mounted to the extension case (from the outside of the case). The sensor outputs a pulse signal which is transmitted to the TCM where it is converted to vehicle speed.


The transfer clutch drum is connected directly to the rear wheel driving propeller shaft. Vehicle speed sensor 1 on the AWD model detects rear-wheel speed.

Vehicle Speed Sensor 2 provides vehicle road speed information to the ECM. The ECM uses this data to properly determine ignition and fuel delivery curves. The sensor consists of a reed switch and magnetic rotor turned by the speedometer cable.


One rotation of the magnetic rotor opens and closes the reed switch four times, producing a digital signal which is converted to vehicle speed by the ECM. The sensor operates whenever the vehicle is moving with ignition ON. As the transmission rotates, the speed sensor sends a pulsed on/off signal to the ECM.

The speedometer uses VSS 2 for it's signal.

Hope this helps (remember to rate this answer).

2001 marquis speedometer stopped working. Replaced cluster- nothing, replaced speed sensor-- nothing, checked all fuses-- OK, stopped 3 wks ago when changine out rear air bags. What could the problem be?


check speed sensor signal at sensor and at cluster. Jack up drive wheels, Block other wheels, start car, put in drive. Then check both AC signals. The signal at the cluster is on pins 14 and 16. See diagrams below.

2005 nissan almera,1.5letre.. fault code po725


P0725 NISSAN - Engine Speed Signal

The P0725 Codes is triggered when TCM does not receive the engine speed signal from ECM.

The Engine Control Module (ECM) monitors the engine speed through the Crankshaft Position (CKP) sensor with the engine running, and send signal to the Transmission Control Module (TCM).

Symptoms:
- Engine Light ON (or Service Engine Soon Warning Light)

Possible causes:
- Open or shorted CKP sensor circuit condition
- Poor CKP sensor electrical connection
- Check communication error between the ECM and TCM
- Failed CKP Sensor

Possible solution:
Very common problem with Nissan vehicles, usually replacing the Crankshaft Position sensor takes care of the problem.

Keep us updated.

Abs light and brake light are on. also service


You can test the wheel speed sensors by unhooking the connectors and put ohmeter test leads on the sensor terminals should read around 1100-1600 ohms also the connectors themselves were bad for wires breaking inside the insulation at the connectors from flexing when the wheel is turned back and forth..Note excessive wheel bearing noise from bad bearings have also been known for interferring with clean abs signal also causing abs codes good luck

Have error codes C1175 & P1000 for a 2002 Jaguar X-type 2.5.


C1175 ABS/TCCM Anti-lock braking / traction control LH rear wheel speed sensor circuit fault ABS/TCCM to wheel speed sensor signal circuit (FH33-21): open circuit, short circuit to ground, short circuit to B+ voltage, high resistance LH rear wheel speed sensor failure
P1000 is for check not complete after last memory clear , dont worry about it , just stick with C1175 , and most probably it is the sensor wire

TURN RT APPLY BRAKES ABS/TRAC OFF COMES ON


bad front bearing/abs sensor The sensor is part of the bearing,or the wires are bad so that when you steer it open circuts and thinks the wheel is stopped. need to read codes or use a scan tool with live data to see which wheel the computer thinks is stopping. then look at that wheel for problems
