Question about 1994 Lexus LS 400

1 Answer

Lost horsepower on 94 Lexus LS400 after warm up.

Car went into limp home mode and used a lot of fuel. I had driven it about 30 miles before this happened. I have replaced the right bank o2 sensors and will replace the two on the left soon as they arrive. the DENSO set of o2 sensors only included 2. Am I on the right path ?

O2 sensors WILL NEVER CAUSE A LOSS OF POWER, u are looking in the wrong place, sounds like a fuel starvation problem or a defective MAF, the O2's are just seeing this and setting a code..

My check engine light is on. it is pulling 4 codes P0302 P1670 P0174 P0171


code p 0302 is a misfire on no 2 cylinder
check that the plug lead is on properly, that the lead is operational
move the injector from 2 to another cylinder and see if the misfire follows the move
code p 0174 refers to system too lean bank 2===causes intake /exhaust leak---fuel pressure / pump---injector/s--AIR system--hose connection/s
code p 0171 refers to system too lean bank 1=== causes intake /exhaust leak---AIR system---MAF/VAF sensors---fuel pressure / pump---injector/s -- HO2S
You stated that you replaced the O2 sensor but that is different to the HO2S sensor , does a different job and controls the air/fuel mixture from the ECM
because it has banks 1 and 2 it is a v engine and you will have a HO2S in the exhaust manifold or before the cat converter for each exhaust
O2 sensors are after the cat converter and confirm the HO2S settings for the ECM
to put the lights out , use a scan tool to reset the ECM

2002 eord F150 po174 system adaptive fule too lean bank2


PO174- too lean bank two --is a possible rich
condition driven lean by the pcm

Check for leaking injectors,vacuum leaks,fuel pressure

Look at fuel trim on scanner

The front oxygen sensors get replaced every 100,000 miles,
so there may be some of the problems

Start with fuel trim,cylinder misfires,spark plugs, injectors, on that
bank, as a place to do your testing for the code

Look at freeze frame data & I/M Monitor activity, to see if the O2
Monitors ran clean & look at O2 data

Can a bad o2 sensor (or fuel mixture) cause my passat to go into limp mode? P1196 (o2 sensor 1 bank 1) and P1813 solenoid 1 electrical transmission) are the codes I get. the car runs fine but the turbo...


check the spark plugs and wires. the turbo motors have an aluminum head that expands and contracts too quickly and cracks the ceramic insulator on the plugs causing the engine to run irratically when it starts making boost and drops into a safe mode. also throws the trans code.

PO456 is most times a gas cap or gasket,
to get an incorrect gear ratio the transmission has probably started to slip.

Change the fluid and filter first off in the transmission and use only atf+4 fluid and possibly the govenor pressure sensor,and change gas cap.

My car is xg300 Hyundai the code showing up are p01191 &p1193 , p0136, p0141 what are they will it cost me


Electronic Throttle System codes (P1191 & 1193), Limp Home mode & Low RPM (Detected RPM below 470). This is usually cause by either a sticking throttle plate or an intake air hose leak.

P0136 - O2 Sensor Malfunction (Bank 1, sensor 2), P0141 - O2 Sensor Heater Circuit Malfunction (Bank 1, Sensor 2). Either the sensor is broken, it's been unplugged, or the wiring has been damaged.
