This code is for the heater element in the AF sensor, it is out of range, an AF sensor is the smae as a oxygen sensor, it varies only in the material it's made from, otherwise it does the same thing as any O2 sensor, which is monitor the amount of oxygen present in the exhaust gases, the computer uses this info to control the fuel/air mixture. I think it would be safe to replace the sensor, disconnect the battetry to clear the code. The sensor is located near to (maybe in the exhaust pipe) or in the exhaust manifold, it has a wire connector to it with either 3 or 4 wires. it is barrel shaped and about the size of a magic marker..

Meaning od dtc p1733 on suzuki aerio. what should be done?

get it serviced, the operators guide told you that.
or is this a DIY question? got tools, got scan tool, ? skills?
meaning, well it means some tests failed, on board diagnostics
ran tests (it never stops) and found errors, P1733 is one.
rule 1, only use suzuki books for this error, no others, (no fords,etc)
the suzuki factory service manuals covers this, called the FSM.
the meaning can very by transmission you have.
i think its a transmission code, (3 > 4 shift)? transmission slip.
get it serviced, or diagnoseds.
or reset it
and see if that comes back, like on all dtc errors.

1999 Camry PO125, P1130, P1135. What should I do? Dont want to more alot into it. It's my sons car at school.

Hello. Sorry to hear about your troubles.

The P-0125 DTC:
Specifically, the "coolant temperature is too low for closed loop operation", This indicates a partially stuck open thermostat; the coolant is not reaching the optimal temperature to allow the computer to use the various sensors on the engine; it is staying in a pre-programmed or defult mde.

The P1130 and the P1135 indicates a bad Air-Fuel sensor.
On a 4 cylinder, this would be the one on the exhaust manifold.

Replace the thermostat and the air/fuel sensor. Try to use Toyota parts; it has been shown that 'aftermarket' sensors do not perform very well in Toyotas. If you buy a 'generic' sensor, the code may remain, and you problm will not be fixed.

Thanks for choosing FixYa for asistance.

I have code P1135 on my Toyota 4-Runner

Manufacturer DTC P1135 (for Toyota) means A/F Sensor Heater Circuit Malfunction Bank 1 Sensor 1 (Set when the heater operates, heater current exceeds 8A or heater current of 0.25A or less).
The A/F sensor contains a ECU-controlled heater. At start-up, the heater helps warm the A/F sensors to quickly operating temperature. With minimal exhaust gas flow, the heater keeps the A/F sensor from cooling down.
Take a look
Checking Resistance.
a. Disconnect the A/F sensor connector.
b. Using an ohmmeter measure the resistance between terminals +B and HT. Resistance: 0.8 - 1.4 ohms at 20°C (68°F). If the resistance is not as specified, replace the sensor.
Torque: 44 Nm (440, 31 ft.lbf)
c. Reconnect the A/F sensor connector.
( )
P0125 set if after the engine is warmed up, A/F Sensor Output* does not change when conditions (a), (b), (c), and (d) continue for at least 1.5 min.:
a. Engine speed: 1,500 rpm or more
b. Vehicle speed: 25 – 62 mph (40 –100 km/h)
c. Throttle valve is not fully closed
d. 140 sec. or more after starting engine
*Output values changes inside ECM only
This DTC can be set due to other related parts failure.

P1135 code 2002 toyota highlander 3.0 v6.

P1135 is the A/F sensor Bank 1 Sensor 1. Unfortunately, it is the sensor on the back side of the motor, in the manifold against the firewall. Its extremely common, and its not very difficult to replace, just dont try doing it with the motor hot. If you installed an aftermarket sensor, or an Oxygen sensor instead of A/F, you will still have problems. old exhaust gaskets tend to crumble, dont worry, your air mix didnt cause that. Which sensor was replaced?
