CEL displayed code P0420 & 1150 what could be the problem
Mine is a 2001 Sienna LE. I got the P0420 code and the dealer want to replace an engine control computer for $1600. I've found posts that say you can replace your oxygen sensors, which still costs around $100 each. The P0420 seems to be emissions related. When my check engine light comes on, I run the highest grade, no ethanol gas, and usually within a couple of tanks, the light goes off again. The last time it happened about 2 wks ago, I put in the 93 octane no ethanol premium and a can of Seafoam and within a half a tank, the light went out. Your problem might be more serious, and I don't know what the 1150 code is, but so far that's worked for me.

SOURCE: I have a 2001 Toyota Sienna with a P1135 code
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.

All cars sold in the US after 1995 use the same on board diagnotics called OBD-II. The codes are the same. Search OBM-II error codes and you'll get a listing.
P1150 Air/Fuel Sensor Circuit Range/Performance. (cylinder bank 1 Sensor 2)
P1150 may mean that one or more of the following has happened:
water or corrosion in the O2 sensor connector, loose terminals in the connector, wiring burnt on exhaust components, open or short in the wiring due to rubbing on engine components, holes in exhaust allowing unmetered oxygen into exhaust system, unmetered vacuum leak at the engine, bad O2 sensor or bad PCM.
P1155 Air/Fuel Sensor Heater Circuit. (cylinder bank 1 Sensor 2)
P1155 may mean that one or more of the following has happened: O2 Heater element resistance is high, Internal short or open in the heater element or O2 heater circuit wiring high resistance
Solution :Replace oxygen sensor and see if the problem goes away.
