Ihave a 2003 Jaguar S-Type, What do PO133, PO153 and P1000 codes mean? Afriend said oxygen sensors; how to change the oxygen sensor for a 2003 Jaguar S-Type?

A code P0133 may mean that one or more of the following has happened:

• The oxygen sensor is faulty
• The wiring to the sensor is broken / frayed
• There is an exhaust leak

the problem is more than likely the front Bank 1 oxygen sensor. You will likely wind up replacing it but you should also consider these possible solutions:

• Check and fix any exhaust leaks
• Check for wiring problems (shorted, frayed wires)
• Check the frequency and amplitude of the oxygen sensor (advanced)
• Check for a deteriorating / contaminated oxygen sensor, replace if necessary
• Check for inlet air leaks
• Check the MAF sensor for proper operation
• code p1000 refers to emission monitors not fully run and requires a couple of drive cycles from cold start to fully warmed drive cycle at different speeds.

the p1000 is a system readiness code meaning the car is checking itself..it means its not finished etc but once it has the code will change to p1111..meaning system check completed, the c1165 is a abs or wheel speed code, check the wheel where this code is originating

code P0133 is : o2 sensor circuit slow response (bank 1 sensor 1)
meaning;;;one heater on o2 sensor is not heating fast enough or no heat.
look for o2 sensor heater fuse first
and connector wiring for rust
if ok change o2 sensor

Catalitic converter mailfunction. Possible causes: - catalitic conv. mailfunction - o2 sensor mailfunction (ECU generates p430 from converter pre and post sensors data) - misfire; bad quality petrol, bad spark plugs, bad ignition coils (misfire means cat conv able to burn out without quick repair) - low fuel pressure: petrol filter needs replace, fuel pump needs replace - hole in exhaust system (sensors are ok, but measure wrong flow)

If the Dianosis test Code P1000 is flagged after DTCs have been cleared, all engine management OBD diagnostic monitor drive cycles HAVE NOT BEEN COMPLETED. See http://www.bluejag.co.uk for further details on this

system too lean bank 1. check for vacuum leaks near the sid eof the engine which houses number 1 cylinder.

Code P1347 can be set for either a short to ground, short to power, high resistance or open circuit on Oxygen Sensor for bank 2, (HO2S21). Bank 2 is on your right when standing at the front of the engine facing the crank, and this sensor is the first in line; before the converters.
Code p1111 - Intake Air temperature (IAI) intermittent high voltage-low temperature condition.
Probable Cause:
1. Open circuit to IAI-Check connector
2. Failed IAI
3. Open Circuit Condition

Hope this helps

P1645 EVAP Solenoid Output Circuit
P1000 Scan not complete. meaning it didnt finish scanning

speed sensor

do you have the meaning for the codes? if you do please descrive it, it will help a lot
