1135 is the APP sensor, If this what you replaced and is still acting up. Look at the APP plug, Corrosion will also cause malfunctions. Clean it or replace it.

I have p0700 and p0705 codes, p0455, p1125, and p2125 and p2138 codes


The transmission of a vehicle which has suffered a transmission problem will send the P0700 code to the vehicle engine control module (ECM)

P0705 Transmission Range Sensor Circuit Malfunction

Possible causes

- Open or short park/neutral position switch circuit
- Poor park/neutral position switch circuit connection
- Misadjusted park/neutral position switch
- Park/neutral position switch may be faulty

P0455. A code p0455 most likely means one or more of the following has happened:

A loose or improperly affixed gas cap

A non-conforming gas cap (i.e. not factory/original brand)

Other leak or damaged piece in EVAP system

P1125 Accelerator Pedal Position (APP) System

P2125 Throttle/Pedal Position Sensor/Switch "E" Circuit

P2138 Throttle possition sensor

The code is p1125bb

Diagnostic Test Code (DTC) P1125 Has to do with your Accelerator Pedal Position Sensors (APP).

The APP sensor 1 and APP sensor 2 are potentiometer type sensors with the following circuits.
• A 5-volt reference circuit
• A low reference circuit
• A signal circuit
The APP sensor 1 signal to the PCM is low at rest and increases as the pedal is depressed. The APP sensor2 signal also low at rest and increases as the pedal is depressed. DTC P1125 sets when BOTH of these sensors have a problem. It will not set if only one of the sensors are not reading correctly. This code also does not set alone. There will be at least 2 other APP fault codes set along with this code and these codes MUST be diagnosed first.

Diagnostic code for isuzu rodeo p1125,p1295, and p1550

P1125 is: Throttle Positioning Sensor intermittent.
P1295 is: Multiple faults on bank 1 (right)
P1550 is: Power steering pressure sensor out of self test range.
Well the ECM recognizes 3 codes. Were these codes stored as inactive (in the history section)? Or are these codes all active? Code P1125 and P1295 may be related but P1550 is separate. How else may I help?
